| More microbes that can degrade plastics in places with heavy plastic pollution Posted: 14 Dec 2021 05:45 AM PST The number of microbial enzymes with the ability to degrade plastic is growing, in correlation with local levels of plastic pollution. That is the finding of a new study that measured samples of environmental DNA from around the globe. The results illustrate the impact plastic pollution is having on the environment, and hint at potential new solutions for managing the problem. |
| Source of large rise in emissions of unregulated ozone destroying substance identified Posted: 14 Dec 2021 05:45 AM PST New research has discovered that emissions coming from China of the ozone-destroying chemical, dichloromethane, have more than doubled over the last decade. |
| Melting sea ice forces polar bears to travel farther for food Posted: 14 Dec 2021 05:45 AM PST In recent years, polar bears in the Beaufort Sea have had to travel far outside of their traditional arctic hunting grounds which has contributed to an almost 30% decrease in their population. The bears' home range, or the amount of space they need for food and other resources, was around 64% larger from 1999-2016 than it was in 1986-1998, according to a recent study. |
| Decreased vehicle emissions linked with significant drop in deaths attributable to air pollution Posted: 13 Dec 2021 01:01 PM PST As emissions fell over a decade, the number of deaths attributable to air pollution dropped by thousands, yielding billions of dollars in societal benefits. |
| Low-cost AI soil sensors could help farmers curb fertilizer use Posted: 13 Dec 2021 08:17 AM PST Smart sensing technology to help farmers use fertilizer more effectively and reduce environmental damage has been created by bioengineers. |
