Comments Off on Sustainable agriculture cleans up rivers in Cuba

New scientific findings reveal that Cuba’s rivers are in better health than the Mississippi River. The research was a joint effort between Cuba and the United States, marking the two countries’ first collaboration in more than 60 years. The work was part of a study on Cuba’s hydrology, focusing on the water quality of the island’s rivers. Despite centuries of cattle and sugarcane farming, research results reveal there hasn’t been much damage to Cuba’s rivers thanks to the country’s other sustainable agriculture methods. Compared to the Mississippi River, Cuba’s 25 rivers surveyed showed lower nutrient concentration of phosphorus and nitrogen pollution. This is likely attributed to Cuba’s shift toward sustainable agriculture , particularly the country’s shunning of imported synthetic chemicals. Related: Dutch company collects plastic pollution from rivers to make parks and products “A lot of stories about the value of Cuba’s shift to conservation agriculture have been based on fuzzy, feel-good evidence,” explained geologist and researcher Paul Bierman. “This study provides hard data that a crucial part of this story is true.” By contrast, the U.S. has more widespread dependence on chemical fertilizers . Hence, dead zones occur where the Mississippi River mouth opens into the Gulf of Mexico, adversely affecting the region’s marine ecosystems with dangerous bacterial and algal blooms caused by elevated nitrogen levels. Another interesting finding is that even though more than 80% of the Cuban river samples had E. coli bacteria, the source was found to be from fecal material by cattle and horses grazing along the riverbanks. The research team believes that this is partly attributed to “Cuba’s intensive use of horses and other draft animals for transportation and farm work.” The researchers concluded that the island country has been committed to promoting more sustainable agriculture to improve both its soil and water. The efforts have led to promising results. The American team was comprised of University of Vermont geologist Paul Bierman and Oberlin College geoscientist Amanda Schmidt. The Cuban team was led by Rita Hernández, representing the Cienfuegos Center for Environmental Studies, an ecological research group. Their joint research, supported by the U.S. National Science Foundation, was recently published in the GSA Today journal of the Geological Society of America. “This research can help the people of Cuba,” Hernández said, “and may give a good example to other people in the Caribbean and all over the world.” + The Geological Society of America Via Phys.org Image via Wikimedia Commons

Comments Off on Plants to give your loved one this Valentine’s Day

Valentine’s Day is a time to shower your loved ones with thoughtful gifts to let them know how much they mean to you. While jewelry, chocolate and roses have traditionally been associated with the holiday, that special person will surely appreciate a gift that lasts longer — a houseplant. There are so many options of colorful plants that give the gift of fresh air and reminders of your love for years to come. Plus, houseplants are a sustainable, zero-waste option the planet will appreciate, too. Here are some ideas that could make this Valentine’s Day romantic and also thoughtful for both your partner and the planet. Heartleaf Philodendron When you decide to give a living plant for Valentine’s Day, it makes sense to choose one with heart-shaped leaves. There are around 200 varieties of philodendron, so look for one labeled ‘Heartleaf’ or ‘Sweetheart’. Not only does it fit the theme of the holiday, but it’s very easy to care for and keep happy. The heartleaf philodendron requires low to medium light and is forgiving if you forget to water it occasionally. Related: How to make an enchanting terrarium necklace to keep or give as a gift Cyclamen While the heartleaf philodendron does not produce a bloom, the cyclamen produces an attractive display of papery flowers with a heart-like shape. Standard colors are pink, red, burgundy or white, but there are many hybrids available. The flowering cyclamen blooms in the winter, which is perfect for Valentine’s Day, and it will re-bloom year after year with proper care. It is a bit of a fussy plant, preferring controlled temperatures and precise watering. Hoya Kerrii This ‘sweetheart’ plant is the perfect gift with distinctively heart-shaped leaves. Although the Hoya kerrii is often sold as a single-potted leaf, you can obtain this as a plant, too. Like most succulents , it has low-maintenance requirements in low light and moderate temperatures. Green Nephthytis Another evergreen, heart-leaved option is the Green Nephthytis. Fortunately for your recipient, it is easy to care for, and this vine works well in a pot on a bookcase or in a hanging basket. Anthurium In addition to heart-shaped leaves, the ‘flowers’ are also heart-shaped, so this plant offers double the love. Plus, it’s a striking plant known for its almost fake-looking waxy leaves and vibrant blooms. Provide anthurium with a bright space outside of direct sunlight in a humid environment, and you’ll get a cycle of blooms each year. Related: Valentine’s Day flower deliveries come at a huge cost to the environment Phalaenopsis This type of orchid brings a “wow” factor to your gift, with unique, long-lasting blooms that are available in a variety of colors. Because they typically bloom from late winter well into spring , Valentine’s Day is the perfect time to get a phalaenopsis settled into place. They prefer filtered light and consistent water. Golden Pothos Another “hearty” (or hardy) plant to grow, the Golden Pothos is likely to be around for decades. As a trailing vine, it will thrive on the top of a cabinet or in a hanging basket. Although it prefers bright, indirect light, it will likely adapt in a darker environment or accept fluorescent lighting as its light source. The golden pothos is also forgiving if the watering schedule isn’t quite followed. Succulents Succulents make a great gift, especially on Valentine’s Day. They have the ability to provide tropical appeal without asking for much in the way of care, and they bring a feeling of zen to any space. Succulents make a statement, so giving one as a gift offers an experience for your sweetheart that will last long after the rosebuds would have faded. Seeds or Bulbs If you require a smaller gift, your love interest is in the middle of a move or you’re shipping something across the country, why not consider seeds or bulbs? Especially for those who enjoy gardening, seeds or bulbs will likely deepen a connection between your sweetheart and you based on your thoughtfulness. You can also plant the seeds or bulbs and allow your gift to grow with the seasons. For example, tulips likely won’t be above the soil level for several more weeks, but your loved one will think of you when those plants finally bloom. Daffodils and crocus are two options that might be blooming as the holiday arrives, depending on where you live. As you shop for plants this Valentine’s Day, check with your local nurseries for advice about what plants to purchase and how to care for them. One benefit of shopping locally is that many selections will already be potted, eliminating the plastic packaging and pots. Of course, there are many online merchants who ship plants and aim to minimize waste, so do your research and email companies if you have any questions. Images via Shutterstock

Comments Off on Urban Rivers designs a multiplayer Trashbot Game to clean the Chicago River

The non-profit organization Urban Rivers is currently fundraising to deploy a remote-controlled, trash-cleaning robot on the Chicago River. Urban Rivers already has a prototype out in the water and hopes to expand this into a full-fledged, multiplayer internet game. The organization’s “Trashbot Game” would allow players to control the robot from afar using simple keyboard directions to gather trash throughout the river. “We really hope that one day, this game is just so boring, because there’s no more trash left to clean,” said Urban Rivers co-founder Nick Wesley in the project’s Kickstarter video . Prior to its Trashbot initiative, Urban Rivers established a floating garden in Chicago, which was maintained by staff on kayaks . The workers began to notice that trash continuously drifted into the garden and eventually became too burdensome for manual clean-up. “Trash appeared at random times in large quantities. Sometimes we would remove all the trash and two hours there was more,” writes Urban Rivers . The garbage also affected local wildlife that depend upon the river and its floating garden. To solve this problem, Urban Rivers created Trashbot. Once fully developed, users will be able to log on from anywhere in the world to control the robot as it collects trash, which will later be removed by staff. Related: Baltimore’s floating trash-eaters have intercepted 1 million pounds of debris In the envisioned Trashbot game, users will be able to see through the “eyes” of Trashbot and gain points for collecting more trash . If Urban Rivers reaches its $5,000 goal, a second version of Trashbot will be developed while a high-powered WiFi hotspot and a home base trash station will be installed on-site. GPS tracking and a theft-prevention tether on Trashbot will also be funded. Via The Verge Images via Urban Rivers

Comments Off on New subway-style map shows how US rivers connect cities and national parks

When we think of transportation in the United States, we don’t always think of rivers . But according to designer Theo Rindos , the country’s waterways once were and still worthy of travel. He designed a subway-style map of America’s major rivers inspired by Harry Beck’s 1933 London Underground Tube Map . The new map reveals how rivers connect cities and national parks in the country. Rindos, a Yonkers-based illustrator, grew up in Montana near the Yellowstone River , where he spent his childhood rafting, tubing, and fly fishing. He translated his love for the water into a crisp subway map, Major Rivers of the United States, featuring the country’s major rivers like the Mississippi River , the Rio Grande, and, of course, the Yellowstone River. Related: Sierra Club Draws a Subway Map of America’s National Parks Data from the United States Geological Survey , Wikipedia, and Google Maps helped Rindos draw up the map, with the the iconic 1930’s map influencing his design . Rindos told CityLab, “London is a very old city and the streets are not laid out in a grid, but Harry found a way to transform something chaotic into something clean, readable, and beautiful. I wanted to take something completely natural and structure it as a transit system, because technically these rivers once were and still are a form of transportation.” He prioritized rivers key today in shipping and transportation, although left some, like the Potomac River, off the map for aesthetic purposes. The ends of each line generally indicate river sources. Stops on the map are towns and cities along the waterways. Smaller rivers, like the Pecos River or the Sacramento River, are drawn on as bus routes. Rindos also divided the country up into 18 Watershed Hydraulic Unit Code zones, like New England or the Great Lakes.

Comments Off on Google enters nuclear fusion clean-energy race

Nuclear fusion is the holy grail of sustainable energy — a potentially unlimited source of pollution-free energy that can power the world. No greenhouse gas emissions. Only helium and a neutron are produced. Now Google has jumped into the race to commercialize nuclear fusion technology, teaming up with California-based fusion company Tri Alpha Energy to develop a new computer algorithim that optimises plasma — an ionized gas that conducts electricity. “Google is always interested in solving complex engineering problems, and few are more complex than fusion,” wrote Ted Baltz, senior staff software engineer, Google Accelerated Science Team, on Google’s research blog . “Physicists have been trying since the 1950s to control the fusion of hydrogen atoms into helium, which is the same process that powers the Sun. The key to harnessing this power is to confine hydrogen plasmas for long enough to get more energy out from fusion reactions than was put in. This point is called ‘breakeven.’ If it works, it would represent a technological breakthrough, and could provide an abundant source of zero-carbon energy.” Related: These mini spherical reactors could help scale fusion energy by 2030 The research was published Tuesday in the journal Scientific Reports . The Optometrist Algorithm achieved a 50 percent reduction in the energy loss rate and an increase in ion temperature and total plasma energy. Other private and public entities are racing to become the first to bring nuclear fusion to scale. Experimental testing includes the Iter project in France, the Wendelstein 7-X (W7X) stellarator in Germany and the Tokamak ST40 reactor in the UK. General Fusion , a Canadian company, is also working to develop nuclear fusion technology. + Tri Alpha Energy + Achievement of Sustained Net Plasma Heating in a Fusion Experiment with the Optometrist Algorithm Via The Guardian Images via Tri Alpha Energy , Google Research Blog

Comments Off on First estimate of plastic entering oceans from rivers yields shocking results

How much plastic do rivers dump into the world’s oceans ? The Ocean Cleanup decided to find out. They conducted what they say is the “first-ever estimate of plastic emissions from rivers” and the results are shocking, as in, between 1.15 and 2.41 million metric tons annually shocking. They say knowing the trash’s origins will help them better deploy their plastic-scooping cleanup arrays. Scientists have known for a long time rivers deposit plastic into oceans, but before this study no one had ever quantified just how much plastic is flowing from rivers, or how much each river contributes, according to The Ocean Cleanup . To answer such questions, researcher Laurent Lebreton of The Ocean Cleanup designed a model drawing from data on waste management , population density, dam locations, hydrography, and topography. Related: Redesigned Ocean Cleanup arrays to start scooping up Pacific garbage patch within a year The researchers found out of 40,760 rivers, a mere 20 contribute two thirds of the plastic input. The plastic also enters oceans more heavily between May and October: three quarters of plastic released makes its way into ocean waters then. The Ocean Cleanup created an interactive map to help visualize the issue. The map tells a user how many kilograms of plastic have entered the oceans just since they started viewing it. You can check it out here . The Ocean Cleanup founder and CEO Boyan Slat said in a statement, “We’re pleased to see how many initiatives have been taken in the past few years to raise awareness of the ocean pollution problem. However, for our work in the deep ocean to succeed in the long run, it’s crucial that governments and other organizations speed up their efforts to mitigate the sources of the problem we aim to resolve. The results of this latest study can assist with those efforts.” The journal Nature Communications published the study online today . Four Ocean Cleanup researchers were joined by one scientist from North Carolina State University and an expert from HKV Consultants in the Netherlands . + The Ocean Cleanup Images via The Ocean Cleanup

Comments Off on A spectacular staircase draws you into this breathtaking daylit loft in Vienna

This renovated loft in Vienna has a sculptural staircase at its core that appears to support the entire upper floor. Design studio Smartvoll sought to preserve as much of the original space as possible while cultivating a minimalist feel reminiscent of Adolf Loos’s interiors. The renovation of the 3,767-square-foot Loft Panzerhalle introduced an abundance of natural light into the interior. The architects left the ribbon windows on the upper floor intact instead of creating galleries typical in modern loft design . An impressive central staircase sweeps upwards like a concrete sculpture, rounding off the composition. The staircase also divides the room while creating a roof over the kitchen, recesses and elevations. Related: Architects turn a cramped apartment into a gorgeous loft where the owner’s cats can roam freely While concrete dominates the space, semi-transparent materials were used to delineate the guest area and bedroom. All the furniture looks integrated into the construction, celebrating free space and minimalist aesthetics. “We wanted to revitalize the space’s original charm,” said the architects. “Magnanimity and a spatial experience of both storeys were priorities. In all dimensions.” + Smartvoll Architects Via v2com Photos by Tobias Colz/smartvoll

Trump begins process of rolling back Obama-era clean water rule

Comments Off on Trump begins process of rolling back Obama-era clean water rule

As part of his ongoing campaign to repeal and undermine many of Barack Obama’s environmental accomplishments, yesterday President Donald Trump signed an executive order directing the EPA to roll back a 2015 regulation known as “Waters of the United States” rule. The regulation gives the federal government the authority to limit pollution in major bodies of water, rivers, streams, and wetlands. Trump’s executive order, on its own, can’t repeal the rule. However, he’s directed the controversial new EPA head, Scott Pruitt, to begin the complex legal process of rescinding and rewriting the rule, which the New York Times writes could take longer than Trump’s first term to actually carry out. The rule was originally created to clear up confusion about the federal government’s authority in regulating streams, wetlands, and major bodies of water after a series of court decisions created legal confusion. Related: New EPA chief Scott Pruitt’s emails reveal troubling oil-industry ties Though the rule was put forward jointly by the EPA and Army Corps of Engineers, many business owners in industries including property development, oil and gas , and fertilizer and pesticide manufacturing claim it stifles economic growth. Environmentalists, on the other hand, contend that it will help provide healthier drinking water and cleaner natural areas to people around the nation. This isn’t the only environmental executive order Trump’s expected to sign in the near future. Reports are also circulating that in the coming week he’ll sign a similar order directing the EPA to dismantle Obama’s 2015 climate change regulations as well.

Comments Off on Philippines president Duterte signs Paris agreement

It’s been almost a year since leaders from 170 countries met in New York City to formally sign the Paris climate change agreement , and almost four months since the agreement officially went into force . But president of the Philippines Rodrigo Duterte is only now jumping on the climate change -fighting bandwagon, finally signing the historic accord. Duterte initially resisted signing the agreement; he claimed it favored rich countries like the United States, and threatened to boycott the agreement because it would hurt industrialization in the Philippines. But his protests subsided last November, when he said a cabinet decision swayed him to support the Paris agreement. Now that he’s signed the deal, it will need to go through the country’s Senate. Related: Hard-won Paris climate agreement officially goes into force Senator Loren Legarda said, “We are a step away from full ratification and it is my commitment to actively shepherd the Senate’s immediate concurrence.”It’s expected the Senate will back ratification as Duterte’s allies populate the governing body. Should the agreement finally go through, the Philippines would receive access to the Green Climate Fund , a global initiative slated to send billions of dollars to developing nations to help them combat climate change. Manila , the country’s capital, has set a goal of reducing greenhouse gas emissions by 70 percent by 2030. The ambitious target will require financial and technical support. Duterte has been labeled a strongman and a firebrand. Vox described him as the Donald Trump of Manila, although the former Davao City mayor has been in politics for decades. Trump and Duterte have become fast friends – Trump reportedly praised Duterte’s war on drugs, which is so violent it sparked a January report from Amnesty International .
