Doctors in Delhi, India’s capital region, have declared a public health emergency over the densely populated, metropolitan area’s extremely high level of air pollution , the breathing of which has been described as the equivalent of smoking 50 cigarettes in a day. The Indian Medical Association has called for the capital city’s upcoming half-marathon to be cancelled to avoid “disastrous health consequences” and urges residents to remain inside to protect themselves from the pollution. Arvind Kejriwal, chief minister of Delhi, described the city as “a gas chamber,” according to the Guardian , while he and other officials work to determine an effective response to the crisis. As the region struggles to breath, state and federal government have been urged to take action to protect its citizens. In response to the public health emergency, schools have been closed while transportation routes have suffered delays under the decreased visibility. While the smog contains a number of noxious chemicals, the most destructive are concentrations of fine pollutants smaller than 2.5 micro-meters, which are so tiny that they are able to slip through natural filters in the human body. These fine pollutants, which include lead, arsenic, cadmium and mercury, have reached concentrations in the air eleven times the level defined as safe by the World Health Organization. “It has terrible effects on every part of your body,” said Dr. Arvind Kumar, chest surgery chairman at Sir Ganga Ram hospital in Delhi, according to the Guardian . “It can precipitate an acute asthma attack and in the long run it will increase their risk of lung cancer .” Related: India to only sell electric cars by 2030 Delhi’s air is polluted for much of the year due to open burning of trash, road dust, exhaust from vehicles, and byproducts of industrial activity. However, it becomes even more unbearable in winter when seasonal changes trap the pollution closer to the ground. Attempts to improve Delhi’s air quality have included traffic rationing, shuttering of local coal power plants , and even banning fireworks during Diwali. Unfortunately, to truly tackle this urgent problem, local, state, and federal governments will need to examine the complex systems that result in an outpouring of pollution and craft comprehensive policies to discourage unhealthy practices and encourage healthy ones.

EPA cancels plan to clean up polluting Texas coal plants

Comments Off on EPA cancels plan to clean up polluting Texas coal plants

Big Brown, a coal -fired Texas power plant, spews out sulfur dioxide at rates as much as 50 times higher than coal plants fitted with newer technology. Under President Barack Obama , the Environmental Protection Agency (EPA) aimed to clean up Big Brown and six other Texas plants in three to five years. But President Donald Trump’s EPA, headed by Scott Pruitt , just released a final rule that will enable these polluting plants to keep on pumping lung irritants into the air. Big Brown and the other six plants together generate more sulfur dioxide pollution than power stations from over 25 states combined, according to Sierra Club senior attorney Elena Saxonhouse. She wrote the former EPA had slated the stations for cleanup, “setting emission limits for sulfur dioxide consistent with modern scrubbers,” equipment that can yank out sulfur dioxide before it billows out of a plant’s smokestacks. The two boilers at Big Brown and nine other coal-fired boilers don’t have scrubbers at all. Four other boilers also part of the proposal do have scrubbers, but they’re from the 1970’s and don’t work as well as modern technology. Related: Trump administration halts study on health risks of living near coal mining sites But it seems Pruitt doesn’t care about harmful pollutants. He tossed out the proposed rule for a final rule Sierra Club described as a do-nothing plan, where Big Brown and the other plants can go on polluting as normal. Saxonhouse wrote in an article for Sierra Club, “Pruitt’s decision to scrap the proposed clean air protections fits a pattern of backward-looking decisions in this Administration , which has tied itself in knots trying to prop up the coal industry .” The cleanup plan would have implemented the Clean Air Act’s Regional Haze program. The proposed upgrades would have removed over 180,000 tons of sulfur dioxide pollution a year. One analysis found the proposal could have saved over 600 lives every single year. But the final rule means the coal plants can keep polluting, potentially leading to harmful health impacts for humans. According to Saxonhouse, “In making this about-face, EPA had to shove aside reams of technical and scientific data prepared by the previous administration, and ignore the legal framework of the Regional Haze program. And EPA failed to take any public comment on the new plan, despite the fact that thousands of citizens had written in to support the strong proposal.” Via Sierra Club Images via Larry D.

Comments Off on Fixing Earth’s ozone layer has other surprising benefits, new study shows

Dozens of nations signed an agreement nearly 30 years ago to stop the expansion of a massive hole in Earth’s ozone layer. Today, thanks to the Montreal Protocol, the hole in the ozone layer has shrunk as countries reduced, then eliminated, the use of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). A new study from  Geophysical Research Letters  now shows that the agreement not only achieved its stated aim, but has also been one of the most effective tools for fighting climate change in the United States. The recent study confirms what scientists and policymakers have been observing as the Montreal Protocol was enacted, though it focuses primarily on the United States. “This is something that’s been talked about for a while, this dual benefit of the Montreal Protocol limiting damage to the ozone layer, also curtailing climate change,” said Rachel Cleetus, climate policy manager and lead economist with the Climate and Energy program at the Union of Concerned Scientists. “It’s because all these ozone depleting substances are also very potent global warming gases.” The regulations enacted to fulfill the Montreal Protocol resulted in greenhouse gas reductions equivalent to approximately half of all other climate regulations between 2008 and 2014. Related: Antarctic ozone layer shows “first fingerprints of healing” The near-total removal of CFCs and steep decline in HCFCs in the United States was made possible by the Clean Air Act , a law that was used by the Obama Administration , as approved by the Supreme Court in Massachusetts v. EPA, to reduce greenhouse gas emissions. Though CFCs and HCFCs have been replaced by hydroflourocarabons (HFCs), which still contribute to climate change but do not burn a hole in the ozone layer, the signatories to the Montreal Protocol have amended the agreement to reduce HFCs as well in a move that was praised by US Secretary of State John Kerry as the “single most important step” in combating climate change. As the Trump Administration refuses to fulfill its duties under the Clean Air Act to protect public health, the success of the Montreal Protocol is a hopeful reminder of what can be done if dedicated parties work together and take action.

Comments Off on Swiss grocery store chain will be the first to sell insect burgers

Would you eat a burger made of mealworms? Coop , the second-largest supermarket chain in Switzerland , will start selling food made with insects . The country will be the first in Europe to allow sales of insect-based food for people, thanks to laws changed in May. Coop will sell insect burgers and balls from Switzerland-based startup Essento . Switzerland’s food safety laws allow sales of food made from mealworms, crickets , or grasshoppers. Coop will be selling Essento Insect Burgers and Essento Insect Balls, both made with mealworms. The burgers also contain rice, vegetables like leeks and celery, and spices like chili and oregano. The balls – which could be eaten inside pita bread, for example – are filled out with chickpeas, garlic, onions, parsley, and coriander. Related: BUG BUG cutlery set might just make you want to eat insects Coop Head of Category Management Silvio Baselgia said they’re Switzerland’s first retailer to sell Essento’s insect products, which the company has been developing for more than two years. Essento co-founder Christian Bärtsch said in a statement, “As food, insects are convincing in many respects: they have a high culinary potential, their production saves resources, and their nutritional profile is high quality. Thus insects are the perfect complement to a modern diet.” According to Essento’s website, mealworms don’t produce as many greenhouse gases as animal food sources like pigs or cows. 80 percent of insects are edible, as compared with 40 percent of cows, and raising insects requires less food and water. Insects are a good source of protein and also contain unsaturated fatty acids, the vitamins A, B, and B12, and minerals like zinc, potassium, calcium, and iron. Essento’s products will be on sale on August 21 in seven Coop stores to start, including branches in Zurich and Geneva. + Essento Via The Guardian and Coop Images via Essento Facebook and Coop

Comments Off on Spectacular ‘Dome of Visions’ greenhouse pushes the envelope for wood construction

Finnish company Metsä Wood is known for pushing the envelope when it comes to building with wood. Their latest greenhouse dome is the largest to date – and it showcases the company’s innovative use of laminated veneer lumber as a sustainable alternative to commonly used building materials. The structure, named Dome of Visions, was designed by Atelier Kristoffer Tejlgaard  as a way to explore green building. The Dome of Visions 3.0 is the third project in a series of experiments that explore the idea of creating sustainable spaces within dome-shaped structures. It has a new system of curved wooden beams , composed of 21 mm strips of Kerto LVL (Laminated Veneer Lumber). This made it possible to minimize the amount of steel while achieving both a sleek and elegant grid construction. Related: Architect designs life-sized replica of Empire State Building made of wood Using curved wooden beams, the brackets for the dome’s supports were cut as stars in a five-millimeter steel plate. The custom-made Kerto beams made it possible to avoid the use of complicated and costly welded brackets used in previous versions. Related: Mobile Greenhouse Studio Boasts a Facade of CNC-Cut “Fish Scales” in Copenhagen “Wood as a building material has obvious advantages giving sustainability for the building industry. In principle, wood is a material that comes from a solar-powered factory,” said Kristoffer Tejlgaard, referring to the ability of trees to extract CO2 from the atmosphere and store it as carbon in their trunks, solely by means of solar energy . + Atelier Kristoffer Tejlgaard + Metsä Wood

Pollution cuts solar energy production by up to 35%

Comments Off on Pollution cuts solar energy production by up to 35%

We may be sabotaging our efforts to generate clean energy . New research from a team led by Duke University found polluted air may be reducing our solar energy output – by 25 percent. And areas with some of the highest investment in solar power are those impacted the most: China , the Arabian Peninsula, and India . Dust and airborne particles may be harming our ability to generate as much solar energy as we can. Duke University engineering professor Michael Bergin said, “My colleagues in India were showing off some of their rooftop solar installations, and I was blown away by how dirty the panels were. I thought the dirt had to affect their efficiencies, but there weren’t any studies out there estimating the losses. So we put together a comprehensive model to do just that.” Related: Students Create Award-Winning Robot That Cleans Solar Panels Joined by researchers from the Indian Institute of Technology Gandhinagar (IITGN) and the University of Wisconsin at Madison , Duke University scientists found pollution accumulation is indeed impacting solar energy output. They measured the decrease in energy from IITGN’s solar panels as they got dirtier. Each time the panels were cleaned after several weeks, the researchers noted a 50 percent boost in efficiency. China, India, and the Arabian Peninsula are the areas of the world impacted the most. Even if their panels are cleaned monthly, they still could be losing 17 to 25 percent of solar energy production. And if the cleanings happen every two months, the losses are 25 or 35 percent. Reduced output costs countries not just in electricity but money as well. Bergin said China could lose tens of billions of dollars yearly, “with more than 80 percent of that coming from losses due to pollution.” He pointed out we’ve known air pollution is bad for health and climate change , but now we know it’s bad for solar energy as well – all the more reason for politicians to adopt emissions controls. The research was published online this month by the journal Environmental Science and Technology Letters . Via Duke University Images via Duke Engineering on Twitter and Pexels

Comments Off on India to only sell electric cars by 2030

India is taking huge strides to escape its dubious distinction as one of the most polluted countries on Earth. The government is taking dramatic measures to clean the country’s air – including the switch to sell solely electric cars in just 13 years. If the amount of diesel and petrol cars dwindles on the streets of India, the country could lower the dangerous levels of air pollution that have led to the deaths of 1.2 million people annually. Energy minister Piyush Goyal said India would financially back the move for the first two to three years; then electric vehicle production will be “driven by demand and not subsidy.” Related: New Delhi has the worst air pollution of any city on earth The move has been praised by environmentalists and, naturally, worried the oil industry. India is the third biggest oil importer in the world – each year they spend $150 billion on oil. Moving to electric cars could save the country $60 billion in energy expenses. Indian car owners would also save money by switching to electric vehicles . Goyal, who presented the government’s plan at the Confederation of Indian Industry Annual Session 2017 in New Delhi, said the government would invest in charging infrastructure, beginning in big urban areas like Delhi. He also said they were considering methods like swapping batteries “so cars don’t have to wait for batteries to be charged,” saying, “Electric cars can then move to petrol pumps, swap their batteries, and drive out, just like they do now. And it will take less time than what it takes to put petrol in your car, like in Formula 1 races!” The transition to electric cars would also help the country slash greenhouse gas emissions. Calculations indicate India’s carbon emissions could decrease 37 percent by 2030 with the move to electric vehicles.

Comments Off on It took more than 25 years to build this incredible walkable world map

You’d need around 11 years to walk around the globe – if you can walk on water. But a world map in Denmark makes the feat possible in a few minutes. Verdenskortet , or world map , is a walkable map , made of soil and stone, built on top of a pond. It took Søren Poulsen more than two decades to complete this extraordinary project, and it was worth the wait. Poulsen, who was born in 1888 in Denmark, realized a stone on his land was shaped similar to the Jutland Peninsula. That stone launched the idea to create a world map, and Poulsen started the project in 1944. He continued working on the map, located at his childhood home at Klejtrup Lake, until he died in 1969. Today the map comprises the center of a park offering outdoor activities and event space. Around 35,000 people visit every single year. Related: Our World: A Giant Pixelated LEGO Map Built from 1 Million Bricks! Poulson made the map out of rocks and dirt, using just hand tools, a pushcart, and a wheelbarrow. The Verdenskortet Facebook page explains the stones comprising the world map were moved onto the ice during winter, and then in spring the stones could be moved into place. Flags mark each country, and there’s even yellow bricks dividing America up into states. Red poles indicate where the equator lies. The world map is 300 feet by 150 feet, and every 10 inches represents around 69 miles in the real world. Today the park offers guided tours of Verdenskortet, paired with coffee and cake. People can play miniature golf on the grass, or take a class field trip to the map. Visitors can take a boat trip around the mini Pacific Ocean , and on land go on pony rides, play old Viking games, or jump on a trampoline. Park entry is inexpensive; around $12 for adults and $8 for kids. + Verdenskortet Via GOOD Images via Verdenskortet Facebook

BREAKING: Trump announces U.S. will withdraw from the Paris Climate Agreement

Comments Off on BREAKING: Trump announces U.S. will withdraw from the Paris Climate Agreement

During a highly anticipated speech at the Rose Garden, climate denier President Donald Trump announced that the United States of America will withdraw from the Paris Climate Agreement secured under Barack Obama’s leadership. President Trump stated that the accord was “bad” and poorly negotiated by the Obama administration, and that he “is keeping his campaign promise to put American workers first.” Part of Trump’s speech read, ”The Paris Accord is a BAD deal for Americans, and the President’s action today is keeping his campaign promise to put American workers first. The accord was negotiated poorly by the Obama administration and signed out of desperation. It frontloads costs on the American people to the detriment of our economy.” Before the announcement was officially made, Donald Trump was cited by The Daily Best telling congressional staffers on a conference call that he is withdrawing from the Paris accord. Energy policy adviser for the White House, Michael Catanzaro, confirmed that “the United States is getting out of the Paris agreement.” Catanzaro added that Trump “will be open to and will immediately be looking for a better deal.” Reportedly, the Trump administration will follow steps for withdrawal laid out in the agreement. In total, says Catanzaro, removing the U.S. from the deal will take four years. “But we’re going to make very clear to the world that we’re not going to be abiding by what the previous administration agreed to,” he said. Despite the fact that countries such as Costa Rica run on 100% renewable energy and Denmark once generated 400% of the power it needs from wind turbines , the Trump administration remains resistant to transitioning the U.S. to run on renewable energy resources. This is because President Trump, a businessman, believes that energy sourced from fossil fuels is the solution to making America great again – and he thinks climate change is a “hoax” invented by the Chinese . Related: China says they’ll stay in the Paris Agreement – with or without Trump At the time of its signing, 195 countries, including the United States, pledged to reduce emissions that contribute to climate change in order to prevent global catastrophes which may result from rising temperatures. President Barack Obama committed America to a goal of lowering emissions by 26 percent to 28 percent below 2005 levels by 2025. The broad aim was to increase these cuts over time. With the United States exiting the Paris Agreement, carbon emissions are likely to increase, potentially propelling global disasters resulting from rising sea levels , severe weather conditions, and increased temperatures. On a positive note, China and the European Union are prepared to publicly recommit to the agreement with or without the United States. Also, Trump cannot technically withdraw from the agreement until November of 2019. Finally, many U.S.-based companies, including Apple , have ambitious goals to run on 100% clean energy in the near future. With support from educated consumers, the U.S. may reach its previously contracted emissions goal with or without the President’s support. Via CNN Images via Pixabay , Wikimedia Creative Commons

Scientists invent graphene paint that makes your house super efficient

Comments Off on Scientists invent graphene paint that makes your house super efficient

Graphene – the strongest material known to science – is used to create everything from condoms to night-vision contact lenses. Now, thanks to the ingenuity of  The Graphene Company , paint containing the world’s “thinnest, strongest and most conductive” substance is hitting shelves in the UK. The new lime-based paint is incredibly thin, beneficial for the environment and capable of making your home, or any building, more efficient. Because  Graphenstone is composed of a lime-base with a hexagonal lattice of carbon atoms one atom thick thanks to the inclusion of graphene , the lime-based paint has superconductivity , which means it can improve the thermal regulation of buildings. As Dezeen reports , this means the invention lowers the necessity for heating and air conditioning. According to The Graphene Company director, Patrick Folkes, ”When used on interior wall surfaces, rather than heat being radiated through the walls, the graphene within the paint captures the heat. It then conducts the heat through the paint, and across the whole Graphenstone-painted surface of interior walls. This enhances the insulation measures used in buildings by slowing heat conduction through walls and out of buildings.” Because graphene is one atom thick in the paint, less is required to achieve a durable finish that is resistant to corrosion. One liter of paint would cover two eight-meter-square coats, says The Graphene Company. An additional benefit is that the paint is extremely eco-friendly . With a base made from 98 percent pure lime, the paint purifies the surrounding air as it absorbs carbon dioxide. For this reason, the company boasts it is “the most sustainable and eco-friendly paint in the world”. “Sustainability is becoming more and more important as people realise the damage that acrylics do to the environment throughout the manufacturing process and its use on walls,” said Folkes. “Graphene’s inclusion in paints, coatings and other building materials exponentially enhances hardness, durability, compression, tensile strength, elasticity, and coverage.” Related: New graphene super batteries charge up in seconds and last virtually forever After the paint is applied, a hard shell forms as the lime hardens up in the carbonization process. According to Folkes, the initial consistency is a “little bit watery.” Over a period of 10 days, however, hard coverage is provided. The best part? No fumes are released in the process. Already, the product has been used to coat the walls of hospitals , hotels, and schools. As demand for the graphene paint increases, it will likely be sold elsewhere in the world. + The Graphene Company Via Dezeen Images via The Graphene Company
