Economy and Policy
A New Catalyst for Producing Hydrogen
We have spoken before about the prospects for using hydrogen as a clean auto fuel as well as an energy storage medium. Most hydrogen is produced using the steam methane reforming process, which requires natural gas, uses lots of energy, and produces carbon dioxide as a waste product. Hydrogen made this way is not really a green fuel.
McDonald’s And Antibiotics
McDonald’s – the world’s largest chain of hamburger fast food restaurants – recently announced plans to source chicken that is free of human antibiotics. The corporation, which is one of the country’s biggest buyers of chicken, is trying to shake its image of offering unhealthy and unnatural foods. The transition to this cleaner meat will take two years.
Designer Wetlands
Drinking water supplies around the world often contain trace amounts of pharmaceuticals, agricultural and industrial chemicals, and other synthetic compounds that can harm reproduction in fish and may be linked to adverse health effects in humans. Many of these chemicals enter the water supply by passing through our bodies, entering the sewage system, and finding their way into rivers and other bodies of water. There are currently no US regulations for medical drugs under the Safe Drinking Water Act, so it is important to attack this problem proactively.
Animals And Earthquakes
There has long been the notion that animals can somehow sense that an earthquake is imminent. The observation is that animals suddenly withdraw and go silent before a quake. While there is plenty of anecdotal evidence for this phenomenon, there has been little solid proof; that is, until recently.
Perennial Rice
Rice is the most economically important crop in the world. It supplies humanity with about a quarter of its calories. Domesticated rice is a short-lived plant that generally dies off after it produces seeds. Rice paddies have to be cleared of vegetation and plowed each year and are highly vulnerable to soil and nutrient loss through erosion, soil compaction and decline in organic matter.
Tough Times For Amphibians
It’s a tough time to be an amphibian. Around the world, millions of frogs, toads, and salamanders are dying from two emerging diseases. The first plague appeared in the 1990s, and is so deadly to amphibians that it is causing what has been described as the most spectacular loss of vertebrate biodiversity due to disease in recorded history.
Zero Emission Buses
Most of the news about electric vehicles relates to passenger cars. We hear about Teslas, Leafs, and hydrogen-powered Toyotas all the time. But there is also an expanding fleet of electric and fuel cell buses starting to appear on urban streets in several countries, including the U.S. and China.
Are Weed Killers Killing Us?
The U.S.-based agrochemical giant Monsanto finds itself at the forefront of another controversy. Monsanto, which dominates the agriculture market with its genetically modified seeds and herbicides, has drawn unwanted scrutiny after a new report linked one of its most popular herbicides to potential health hazards.
A Giant Marine Preserve
The marine life and habitats in the oceans are at risk from the activities of humankind. The three major threats to the health of our oceans are overfishing, marine pollution, and the effects of climate change. National parks established around the world have long been a way to protect and preserve wildlife and habitats on land. Only more recently have marine protected areas come into existence. These are special places in the ocean designated to help protect marine life and habitat.
Seeing Smog And Seeking Solutions
Technology is changing the way we ‘see’ air pollution. Advances in environmental sensors, computing power, and visualization software are allowing researchers to monitor and display air quality in many of America’s cities 24 hours a day, in real-time. This is giving clean air advocates unprecedented access to pollution hotspots.
The True Cost Of Meat
It’s not uncommon for Americans to eat meat at every meal – bacon with breakfast, a turkey sandwich at lunch, steak for dinner. Worldwide, meat production has more than quadrupled since the 1960s, when more meager portions were the norm. And mass production has driven prices down considerably.
Trash Into Treasure
In one of the world’s most impressive reclamation projects, Israel’s largest landfill dump has been turned into a 2,000-acre ecological park three times the size of New York’s Central Park.
Emptying The Skies
Here in the Northeast, winter is slowly giving way to spring. This means melting snow, thawing soils, and the return of migratory birds. The calls of warblers and woodcock and the thrill of spotting waterfowl like heron herald the warmer and greener days ahead.
Better Carbon Capture
Finding an efficient and cost-effective way to capture the carbon dioxide generated by the use of fossil fuels would be a dramatic game-changer in the fight against climate change. We have often heard about clean coal – coal that doesn’t release lots of carbon dioxide when it is burned – but we haven’t really seen it. Our supplies of coal, natural gas, and these days, even oil are plentiful. We just haven’t figured out how to use these things without damaging the environment.
Plastic Pollution
It’s no secret that plastic pollution in the ocean is a huge problem. The most visible sign of this is the Great Pacific Garbage Patch. This accumulation of debris is at least twice the size of Texas and can be seen from space. But now scientists have developed a new way to measure ocean trash – and it turns out there’s more than meets the eye.
Eiffel Tower Wind Power
The recent retrofit of the Eiffel Tower – the first in 30 years – included the installation of two custom-designed wind turbines. The 17-foot vertical-axis turbines look more like modern sculptures and are painted to blend in with the rest of the structure. Viewed from a distance, it would be very difficult to spot the additions to the 126-year-old Parisian landmark.
GMO Apples
In February, the first genetically engineered apples were approved for planting and sale in the US by the Department of Agriculture. Two varieties, known as the Arctic Granny and Arctic Golden received the approval. They are genetically engineered to resist browning.
The Dirty Job Of E-Waste Recycling
“Reduce, reuse, recycle” was a popular mantra of the 80s and 90s, encouraging citizens to separate paper, plastic, and aluminum from their trash. But with the exponential rise of electronics like cell phones, laptops, and tablets – recycling has become more complex.
Too Much Solar Power
