Have you ever stopped to think about where your pencil came from or what it’s journey will be once it hits the trash? It’s okay if you haven’t, because one company has made it their mission to not only produce eco-friendly pencils that are available in a variety of colors, but also to give new life at the end of the pencil’s functional usability. Sprout World began as an idea from MIT students on the lookout for a more sustainable pencil and has resulted in over 10 million pencil-to-plant product sales. The Sprout pencil starts with sustainable materials such a cedar casings, clay and carbon-based graphite. At the end of the pencil (where you would expect an eraser to be) is a biodegradable capsule that holds plants seeds. So once you’ve sharpened your way through that much awaited manuscript or copious to-do list, your pencil brings new life in the form of plants. Related: These incredible sea creatures are made from dangerously sharp colored pencils As businesses are pushed towards environmental responsibility, Sprout offers a product they can use to their advantage— and that of the planet. The Sprout pencil sketchpad of clients includes notable companies like Toyota, Disney, Marriott and Coca-Cola. Although the private market is noticing the product, around 90% of Sprout pencil sales are currently to companies for use in marketing promotions— which is a major earth-friendly step in the right direction over landfill -clogging disposable pens or magnets. An appealing selling point is the personalization on the pencil shaft along with the additional marketing bling for the pencil sleeve. The seeds packed into the pencil range from colorful flowers to herbs and even vegetables, and buyers can select their preference. The pencils are available in a traditional grey color, as well as colored-pencil packs. Sprout feels that it is their duty to inspire sustainability through their products as well as their own corporate initiatives. With that in mind, they keep production facilities local in Minnesota for the U.S. and Canadian market instead of shipping manufacturing overseas. This not only minimizes the carbon footprint produced by transporting materials, but also provides American jobs. So what’s next for Sprout World? You won’t have to wait long to find out as the world’s first makeup pencil that also sprouts into plants instead of heading into the trash can is due to hit the market any day. Related: Cindy Chinn carves a tiny family of elephants into pencil tips New Sprout CEO, Sidsel Lundtang Rasmussen says, “The idea behind the plantable makeup pencil – like our other sprouting pencils – is to inspire to make small steps towards a more sustainable lifestyle. If you can plant a makeup pencil, what else can you do to recycle and give your belongings new life? The makeup pencil is also especially good as a gift because the receiver will enjoy it for a long time, as it signals originality and consideration from the giver.” + Sprout Images via Sprout

Comments Off on Seeds on the moon started to sprout for the first time but quickly died

China has taken a major step toward long-term space exploration. Earlier this month, the Chinese moon probe Chang’e 4 carried a container with cotton, mustard and potato seeds , yeast and fruit fly eggs to the moon’s far side (facing away from Earth), and early this week, the China National Space Administration said that those seeds started to sprout. Unfortunately, temperatures dropped and killed the plants. According to the BBC , the project was designed by 28 Chinese universities, and the experiment was contained within a canister 7 inches tall and weighing about 6.5 pounds. It was designed to test photosynthesis and respiration, which are processes that produce energy . For the first time ever seeds 🌱 are growing on the moon 🌑! China’s moon mission success means that astronauts 👩‍🚀👨‍🚀could potentially harvest their own food in space! Learn more 👉 https://t.co/S6dOB3p2Ym via @BBCNews #ZeroHunger #FutureofFood pic.twitter.com/TNssZBLG0R — FAO (@FAO) January 15, 2019 The plants  were in a sealed container on the lunar lander, and the hope was that the crops would form a mini-biosphere. Inside the container, the organisms had a supply of air, water and nutrients to help them grow. The scientists said that keeping it at the right temperature was a challenge, because of the wild temperature swings on the moon , which ultimately killed the first sprout. If the experiment worked, astronauts could potentially begin to harvest their own food in space. That would be incredibly useful for long-term space missions, because they wouldn’t have to return to Earth to resupply. Although the sprout died, the experiment is a move toward this goal. Related: China plans to launch the world’s first ‘artificial moon’ But could these experiments contaminate the moon ? Generally, scientists don’t believe this is something we need to worry about, especially because there have been containers of human waste on the moon for 50 years thanks to the Apollo astronauts. The consensus among experts is that the sprout was “good news.” Fred Watson, astronomer-at-large at the Australian Astronomical Observatory, said that it could be a positive development for future space exploration. “It suggests that there might not be insurmountable problems for astronauts in future trying to grow their own crops on the moon in a controlled environment,” Watson said. “I think there’s certainly a great deal of interest in using the moon as a staging post, particularly for flights to Mars , because it’s relatively near the Earth.” Via BBC and The Guardian Image via Jeremy Bishop

Comments Off on Samson Ogbole is a Nigerian farmer who wants to bring aeroponics to the world

Samson Ogbole is a Nigerian farmer who is trying to solve the problem of land shortages in his native country. Nigeria’s population has now reached 190 million, but there isn’t enough land in the country to grow the food needed for the ever-growing population. So, Ogbole has found a solution — aeroponics. This unconventional method is the process of growing plants in the air without using soil. Ogbole first got involved with soilless farming in 2014, and just two years later founded PS Nutraceuticals, a company that puts cutting-edge agricultural technologies into action to improve the efficiency of food production and to ensure food security. “Soilless growing entails removing the soil component, bringing in substitutes, and applying fertilizer to enable the plants to grow,” Ogbole says. “With soilless farming, we have been able to push for what you call urban farming , where we now have farms in cities such that we are able to cut off the middlemen and marketers.” Ogbole says that there are many advantages to aeroponics, the biggest being that you can grow crops at any time of the year. The method has also allowed them to eliminate pathogens that naturally exist in the soil and affect crops. Related: Farmscape helps communities embrace urban farming  Nigeria needs an estimated 78.5 million hectares of land to produce enough food for the population. But, right now there are only 30 million hectares of farmland under cultivation , according to the International Trade Administration of the United States. And, Ogbole says that only 46 percent of Nigerian soil is fertile to grow crops, so the country needs to take steps towards self-sustainability in food production and let technology play a more prominent role. He believes that the “war of the future will be fought through agriculture .” “We’re bringing in technology into agriculture so that the youth can actually see this as a viable option,” explains Ogbole. “We also want to ensure that food production is no longer seasonal, and we’re also bringing in smart sensor technologies into agriculture so that you’re able to get feedback from your plants.” The farmer added that the future of the economy depends on a few people who have bright ideas and can think outside the box. It is ideas, not money, that solves problems. Via CNN Images via Shutterstock

Comments Off on How to grow a lush garden in your tiny kitchen windowsill

Envision a garden — you probably picture rows of corn neatly spaced across a field or lettuce coming to life in large raised beds. What you might not realize is that produce can grow very well in limited spaces, too. You can transform the confined windowsill in your kitchen into an oasis of herbs, greens and other goodies. In addition to growing flavorful herbs and fresh food, you also bring visual appeal to the space and produce a natural  air filtration system . By growing plants organically, you know what you are eating, and you can save money. It’s also nice to be able to easily pluck fresh flowers, herbs or produce any season of the year. When you’re ready to tackle the challenge, here are some tips and tricks to get you started on growing your own windowsill garden. Picking the best plants for a windowsill garden There are myriad possibilities when it comes to selecting plants for your indoor garden. First, consider your preferences. Are you looking for unique, conversation-starting plants that draw interest, or is your goal to produce as much food as you can from your space? Also think about the amount of time you can dedicate to the garden. Since vegetables need frequent attention, consider durable houseplants if you have less of a green thumb. You can start plants from seed, cuttings or plants. Plants are the easiest and most productive option. Cuttings are started from existing plants. Simply trim off a 3-4 inch section and place it into a jar or glass with the bottom in water. Change your water about once a week to avoid bacterial growth. After roots appear (in a week or two), transfer your cuttings to soil. At first, help your cutting adjust by keeping it quite moist, and then gradually cut back the water as it stabilizes in the soil. If you want to start with seeds, seed trays are a good way to develop individual plants. Use a seed soil or potting soil rather than heavy garden soil , which can be too dense for seeds to grow through. Related: 6 foods you can regrow from kitchen scraps Most compact vegetables will do well in a windowsill garden. Look for dwarf varieties that remain small in size but produce a quantity similar to outdoor gardens . Snow peas, cucumbers, radishes, different types of lettuce, spinach, bush beans, green onions, garlic, chilies, sprouts and microgreens are all examples that will perform well in the right indoor conditions. Also consider porch tomato options, such as cherry tomatoes. Just about any herb will grow happily inside the kitchen. Some great options include basil, dill, cilantro, rosemary, thyme, sage, oregano, dill and tarragon. Choosing plant containers The containers you choose can make a unique, artistic statement or create a peaceful, uniform landscape. Consider whether you want them all to match or if you prefer an eclectic blend. Use terracotta pots in their natural form, or give them a fresh coat of paint.  For a DIY look, cover them in chalk paint and label each pot with the plant it contains. Alternately, select your favorite ceramic pots, baskets or vases; use an old canister, tea kettle, bowls or jars; or gather standard store-bought resin planters. When choosing your planting containers, size is the biggest factor. Make sure you have room for each plant to spread out its root system without confinement. Plants will not be happy with compressed roots. Also make sure that the container you choose will fit on the windowsill. Whether you’re using a rain boot or an antique tea cup, make sure you have a drainage hole in the bottom of your container with some sort of saucer to catch the water that filters through. Finding a home for your indoor garden The location of your windowsill garden can be the difference between success and failure. South-facing windows are best, because they do not suffer from the harsh afternoon heat or struggle to find light. Many plants will thrive in an east-facing window as a second option. Wherever you locate your plants, they should receive at least 5-6 hours of direct sunlight daily. If your space doesn’t allow adequate sunshine , artificial light via heat lamps can do the trick. Set them on a timer to help you out and also to provide more consistent light for the plant. Make sure that your plants don’t come into direct contact with the cold window glass during the winter months, and protect them from the blazing greenhouse effect on hot summer days. Also stay away from areas with drafts, such as fireplaces or central heating vents. Tending to the garden Once you’ve selected your plants, containers and location, it’s time to pamper, watch and wait. Label all of your plants for easy reference. You can also include any care instructions that you want to keep close at hand. Keep your plants moist without providing too much water . You can set up drip systems for consistent watering or simply dip your finger in each pot every few days to feel for moisture. Offer your plants fertilizer every few weeks to boost health and productivity. Watch for signs that your plants are not getting the proper amounts of food, water or sunlight, and make adjustments as needed. Related: Why are my plants turning yellow? After herbs are well-established, pinch them back frequently to encourage bushy growth and keep them from going to seed. If the air in your house is dry from a wood-burning stove or other heat source, lightly mist around your plants weekly to improve humidity. Also rinse your plants every few weeks to deter insects, and be sure to look under the leaves for evidence of bugs. When your garden is thriving, propagate your next round of plants. Take cuttings and get them in water. Cut your green onions without pulling them out of the soil, and they will regrow. After harvesting your garlic, replant individual bulbs to grow again. Windowsill gardens are a great way to enjoy your garden all year without concern for outdoor weather conditions. Plus, it keeps your harvest within arm’s reach, adds variety to your meal plan and sparks visual appeal. Start your own windowsill garden and discover the many joys of indoor gardening for yourself.

Can vertical farming feed the world and change the agriculture industry?

Comments Off on Can vertical farming feed the world and change the agriculture industry?

Year after year, cities expand and pristine natural habitats are turned into farms and pastures to support the world’s growing population . But despite our encroachment into the environment, we still struggle to feed everyone. Vertical farms could offer a solution by producing higher crop yields year-round in less space than conventional agriculture. What is vertical farming? With land for crops and pastures growing scarce — plus the threat of pesticides and herbicides taking a toll on our health and the environment — people are exploring new ways to grow food, such as urban agriculture. In general, this is the process of growing food within city limits – whether on rooftops, in backyards or on balconies. The goal is to provide families with fresh, healthy food that isn’t laced with chemicals — and when you grow your own crops, you can control these elements. Vertical farming is a type of urban agriculture – but vertical farms are often constructed indoors in extremely controlled environments. Crops are grown on shelves that extend upward instead of outward, and the environment is carefully monitored, so crops grow year-round. In addition to growing crops, some vertical farmers have developed ways to grow fish in a self-sustaining system. Water from the plants is recycled into fish tanks, and the waste from the fish becomes fertilizer for the plants. Then, both the plants and fish can be harvested for food. The benefits of vertical farming The benefits of vertical farming are numerous. Farmers can control the crops’ environment in vertical farms, so the plants aren’t subjected to nasty weather conditions or droughts . Humidity, nutrients and water are administered to growing plants to achieve optimum growing conditions. Because of the controlled environment, crops can be harvested more than once a year, resulting in higher yields than traditional farming. Related: The GCC’s first commercial vertical farm launches in Dubai Vertical farms are more sustainable than conventional farms because they use less water (which is often recycled through the system), they take up less space and they use less fossil fuels because they don’t rely on heavy machinery such as tractors and harvesters. Technology helps vertical farmers get the best output from the farm. Tailored lamps help plants get more light exposure, which encourages them to grow faster than crops that rely on the sun. Vertical farms also provide greater protection from insects, thus decreasing the need for harmful chemical products. Downsides to vertical farming While vertical farms can help with local hunger issues and sustainability, there are some barriers that may keep them from gaining worldwide traction. The cost of setting up a vertical farm can be prohibitive. Conservative estimates put the initial start-up cost at around $110,000 , but there are estimates upward of millions of dollars. Finding an abandoned warehouse or building in an urban setting for a reasonable price might be difficult. Since vertical farms rely on electricity for growing lamps and strict environmental controls, the location has to have reliable power — not just any old abandoned building will do. Vertical farms also depend heavily on technology, which can be costly. Keeping the lights on and the environmental controls running will impact energy use — and your budget. Related: The “most technologically-sophisticated commercial indoor farm in the world” will grow 30X more produce Not every crop that is grown traditionally can be raised successfully in a vertical farm. Leafy greens and herbs do the best in an indoor environment, while staple crops like wheat and potatoes are difficult to grow indoors, as are some fruits and vegetables. The crops that can be harvested from a vertical garden are limited. Growing food to feed the hungry is a noble gesture, but it also has to be profitable, especially when the initial cost to set up a vertical farm is so high. If there isn’t a market in your area, it’s a waste of time to grow large amounts of food that you won’t be able to sell. The verdict Despite the downsides, the positives are plentiful. In addition to embracing sustainability and helping combat hunger , vertical farms can also encourage support for local economies. These farms can create jobs, turn a profit and provide a healthy source of food for locals. As technology continues to advance, new approaches will improve the efficiency and productivity of vertical farms. If nothing else, the idea sparks the conversation about changing the agricultural industry and gives us a place to start for finding better, more sustainable ways to grow food.

Trump’s border wall threatens Texas plants and wildlife

Comments Off on Trump’s border wall threatens Texas plants and wildlife

If it is ever built, Trump’s US-Mexico border wall would pose a threat to vulnerable wildlife and plants, as well as to the growing ecotourism industry in the border regions of Texas . Norma Fowler and Tim Keitt, scientists at the University of Texas at Austin, have published a letter that outlines the potential ecological damage from such a major project. Currently, Texas has walls along approximately 100 miles of its border with Mexico. “Up to now, the wall has either gone through cities or deserts,” said Fowler . “This is the Rio Grande we’re talking about here. It’s totally different.” The proposed wall is set to cut through hundreds of miles of protected federal land, including much of the Lower Rio Grande Valley National Wildlife Refuge. “We have high biodiversity because of the river and because Texas extends so far south,” explained Fowler. “I and other Texas biologists are very concerned about the impact this will have on our rich natural heritage.” Fowler and Keitt conducted a scientific literature review of 14 other publications to support the concerns outlined in the letter. The authors express particular interest in the protection of the threatened Tamaulipan thornscrub ecosystem , which once covered much of South Texas. Related: Leaked memo shows that EPA staffers were told to downplay the reliability of climate science The wall could also divide breeding populations of vulnerable animals, such as the ocelot. With only 120 left in the Lone Star State, ocelots could suffer from decreased reproduction and eventually disappear completely from Texas. “Even small segments of new wall on federal lands will devastate habitats and local recreation and ecotourism,” said Keitt. The authors suggested alternatives if the United States does ultimately go forward in its efforts to strengthen the border. According to Keitt and Fowler, “Negative impacts could be lessened by limiting the extent of physical barriers and associated roads, designing barriers to permit animal passage and substituting less biologically harmful methods, such as electronic sensors, for physical barriers.” Via Phys.org Images via  Alejandro Santillana/University of Texas at Austin Insects Unlocked Project and  Andrew Morffew

This plant-based spray makes fruits and veggies last up to four times longer

Comments Off on This plant-based spray makes fruits and veggies last up to four times longer

How do you preserve fruits and vegetables after harvest? Generally, you need cold temperatures. But what if there were an alternative to refrigeration ? That question inspired Santa Barbara-based Apeel Sciences  to create  Edipeel , a post-harvest protection product made with edible extracts from plants . Inhabitat spoke with CEO and founder James Rogers about the product, which forms a micro-climate around each piece of food so it lasts around double the amount of time it would untreated — at least. Hunger continues to be a pressing problem, and as the population grows, humanity must figure out how to feed 10 billion people. This issue formed the basis of a podcast Rogers was listening to while driving through the Salinas Valley. He looked out the window at the greenery of the valley, dubbed the “Salad Bowl of the World,” and wondered how people could go hungry if we were growing so much food. Digging into the issue, he discovered it’s not so much about growing enough calories to feed the planet as it is about keeping what we do grow from perishing. Related: This company wants to turn food waste into building materials — here’s how Rogers found out fruits and vegetables rot through water loss and oxidation. “As a materials scientist, immediately this rang a bell with how people solve this problem for steel ,” he told Inhabitat. “Most people don’t think about it, but steel is highly perishable. It rusts. Metallurgists solved this problem in creating stainless steel, and the way that they did that was by adding additional elements, like chromium or nickel.” Edipeel creates an invisible, edible barrier to keep oxygen out and water in. Apeel recombines edible oils from plants in blends tailored for different kinds of food; think citrus or avocados. The result is a powder that Apeel mixes with water and sprays on the surface of food. It dries into a thin added peel, creating a micro-climate for each piece of produce. “The result is that it can last two, three, four times longer, even without refrigeration,” said Rogers. Worried about harmful chemicals on your food? So were Rogers’ friends. “They said, ‘Hey, sounds like a cool idea, bro, but we don’t want any chemicals,’” Rogers said. Although food is technically comprised of chemicals, some people don’t always think about it that way, so he wondered, “What if we could relegate ourselves only to using those materials that are found in high concentrations in the fruits and vegetables we eat every day to make formulations to use food to preserve food?” Apeel has been developing Edipeel for around six years now with that goal in mind. “We’re not a large chemical manufacturing company saying ‘let’s manufacture a new chemical to solve this problem.’ We’re looking at it from this perspective of: how do we work with nature to solve this problem the right way — not the fast way, not the cheap way, not the way that sacrifices the long-term health of the planet, but how do we solve this with the tool set nature has provided us?” Rogers told Inhabitat. The extracts for Edipeel can come from any vegetable or fruit. “We’re not looking for any weird botanical extract from some crazy flower in the Amazon,” Rogers said. “The materials we need are ubiquitous. If it grows above the surface of the earth, basically we can use it to create our formulations. The materials we’re using are all inert materials. They don’t have any action in and of themselves; they’re just structural. We recompose that structure on the outside of produce. “ Since spoilage is so significant, the way Apeel prices Edipeel means it’s more expensive for retailers not to have it. According to Rogers, “If you’re a retailer and you’re throwing away eight percent of your avocados, we’re able to price our product such that by paying us, you’re still going to save enough money to pay us for the product.” Edipeel is designated “Generally Recognized As Safe” by the Food and Drug Administration and can be used on organic produce. “As soon as you see how it works, you know that this is going to be a thing in the world,” Rogers told Inhabitat. “Seeing it work, even at a small scale, it was like, ‘This is the future.’ It just feels like an eventuality.” This year, Apeel is gearing up to offer Edipeel to commercial partners. Rogers couldn’t say who those partners might be quite yet, but he did say they are premier retailers. + Apeel Sciences Images courtesy of Apeel

Simple genetic modification causes crops to need 25% less water

Comments Off on Simple genetic modification causes crops to need 25% less water

Scientists have discovered that a simple genetic modification may result in crops needing up to 25 percent less water than unaltered plants to produce the same yield. An international team led by scientists at the University of Illinois identified a specific protein called Photosystem II Subunit S (PsbS), which can be altered to encourage a plant to partially close its stomata, the small pores that facilitate gas exchange between plants and their environment. The scientists hypothesized that the closing of stomata would allow plants to retain more water without sacrificing its need for carbon dioxide, the atmospheric concentration of which has increased by 25 percent in less than a century. Stephen Long, study co-author and director of Realizing Increased Photosynthetic Efficiency (RIPE), the international research project behind the study, said in a statement: “Evolution has not kept pace with this rapid change, so scientists have given it a helping hand”. As the world adapts to climate change , less water-intensive crops could be a game changer. “This is a major breakthrough,” explained Long. “Crop yields have steadily improved over the past 60 years, but the amount of water required to produce one ton of grain remains unchanged—which led most to assume that this factor could not change. Proving that our theory works in practice should open the door to much more research and development to achieve this all-important goal for the future.” Related: How fungi made Earth’s atmosphere livable – new study Approximately 90 percent of the world’s freshwater supply is used for agricultural purposes. As populations grow and resources become strained, more efficient plants could be a simple yet effective tool to sustain healthy communities. The research team published their positive results on the modification of a tobacco plant; their next step is to do the same for food crops. “Making crop plants more water-use efficient is arguably the greatest challenge for current and future plant scientists,” said study co-author Johannes Kromdijk in a statement . “Our results show that increased PsbS expression allows crop plants to be more conservative with water use, which we think will help to better distribute available water resources over the duration of the growing season and keep the crop more productive during dry spells .” Via New Atlas Images via University of Illinois

Comments Off on World’s first rechargeable proton battery requires zero lithium

Scientists have created the world’s first working rechargeable proton battery . Designed as an environmentally friendly alternative to lithium ion batteries , it could even store more energy — with further development. Lead researcher John Andrews, professor at RMIT University , said in a statement , “Our latest advance is a crucial step towards cheap, sustainable proton batteries that can help meet our future energy needs without further damaging our already fragile environment .” The proton battery relies on water and carbon, instead of lithium. According to The Guardian , it’s a small-scale prototype that has potential to compete with lithium ion batteries that help us use renewable energy to power homes and cars. RMIT also said when scaled up, proton battery technology could be utilized for “medium-scale storage on electricity grids ,” pointing specifically to the giant South Australia energy storage project as an example. Related: New paper batteries can be discarded with zero ecological impact The working prototype utilizes “a carbon electrode as a hydrogen store, coupled with a reversible fuel cell to produce electricity ,” according to RMIT. Proton batteries could be more environmentally friendly, cheaper, and store more energy than lithium ion ones thanks to the carbon electrode and protons from water, according to Andrews. He told The Guardian this new technology, which could be commercially available in five to 10 years, would potentially compete with Tesla’s Powerwall . He said in the statement, “Future work will now focus on further improving performance and energy density through use of atomically-thin layered carbon-based materials such as graphene , with the target of a proton battery that is truly competitive with lithium ion batteries firmly in sight.” The International Journal of Hydrogen Energy made the corrected proof of an article on the research available online earlier this month. Along with three scientists from RMIT, an engineer from Thapar Institute of Engineering and Technology in India contributed. + RMIT University + International Journal of Hydrogen Energy Via The Guardian Images via RMIT University
