Americans And Beef
There’s ample evidence over the past decade or so that Americans are gradually changing their diets, driven by health concerns among other factors. But there’s one change that really stands out. According to a study by the Natural Resources Defense Council, Americans have sliced their beef consumption by 19% between 2005 and 2014.
India’s Air Pollution
Poor air quality is a major problem worldwide. Exposure to air pollution is linked to the premature deaths of an estimated 6.5 million people every year. This makes air pollution the fourth largest threat to human health, trailing only high blood pressure, dietary risks, and smoking.
Hydrogen On Demand
Researchers at the Technion-Israel Institute of Technology have developed a new method for producing hydrogen from water using solar energy. If successfully developed, their approach would make it possible to produce hydrogen in a centralized manner at the point of sale such as at a fueling station for hydrogen-powered cars.
Greening Vacations
According to the United Nations World Tourism Organization, more than one billion international tourists travel the world each year. Tourism has become a powerful and transformative force for many millions of people. But all this travel is not as positive for the planet. To that end, the luxury travel network Virtuoso assembled a short, simple list everyone can follow to reduce the environmental impact of their travel.
Solar Power In China
Installations of solar power continue to increase rapidly around the world and in no place more than China. By the end of 2016, total solar generating capacity in China reached 77.4 gigawatts, making it the largest producer of solar energy in the world. Globally, there is a total of 228 gigawatts of solar power installed, although that number keeps changing rapidly.
2016 Carbon Progress Report
Last year was a big year for progress in the U.S. power sector. Renewable energy provided nearly 17% of the country’s electricity, up from 13.7% in 2015. The first offshore wind farm in the U.S. opened off the coast of Rhode Island. And most significantly, carbon emissions from the power sector continued to decline and reached the lowest levels in nearly 25 years.
Energy From Jellyfish
Jellyfish are fascinating in appearance but generally are nothing but trouble. Their stings can ruin a tropical vacation but they can cause far more damage than that.
Fracking And Earthquakes
Hydraulic fracturing, or fracking, is the process in which water, chemicals and sand are injected at high pressure to split apart rock thousands of feet below Earth’s surface and release oil or natural gas. And it’s a controversial practice.
Wiping Out Wildlife
According to a new report from the World Wildlife Fund, the world’s animal populations have suffered widespread population declines in the last half century. And thousands of species are now scrambling to survive.
Sharks In Hot Water
The majestic great white shark has been around for a very long time. Its evolutionary origin dates back 14 to 16 million years. And while great whites still enjoy decent populations off the coasts of Canada, Australia, and the United States, the same can’t be said for South Africa’s great whites.
Light Pollution And Early Spring
We have talked about the impact of light pollution on our ability to see stars and the Milky Way. We have also discussed its impact on our circadian rhythms. Recently, scientists in Great Britain published a report on the relationship between light pollution and the timing of when trees produce their buds. The results of the study suggest that light pollution is causing plants to jump the gun on spring.
Lessons From The Forest
For more than half a century, scientists have converged on Hubbard Brook Experimental Forest in New Hampshire’s White Mountains to explore how forest ecosystems work. The site was established by the U.S. Forest Service to study the relationship between forests and New England’s water supply. In the 1960s, inquiry was expanded to include ecology, biogeochemistry, and studies of birds and other animals.
Young Fish Eat Microplastics
We have talked before about the increasing problem of microplastics polluting the oceans. Much of the small plastic particles result from the breakdown of plastic litter such as plastic bags, packaging and other materials. Another source is microbeads, which are often found in health products such as face scrubs and even some toothpastes.
