The Future of the Sea report, released Wednesday for the UK government, found that human beings across the globe produce more than 300 million metric tons of plastic per year. Unfortunately, a lot of that material ends up in our waters, with the total amount of plastic debris in the sea predicted to increase from 50 million metric tons in 2015 to 150 million metric tons by 2025.
One of the roadblocks to swift action on climate change is the human brain's tendency to focus on threats and stimuli that are an obvious and noticeable part of their everyday lives, rather than an abstract and future problem, as Amit Dhir explained in The Decision Lab.
Now, a study published in Nature Climate Change Monday shows that acting quickly to curb greenhouse gas emissions would also reduce the air pollution that is already a major urban killer, thereby saving millions of lives within the next 40 years.
A study published in Nature Climate Change Monday shows that thawing permafrost in the Arctic might produce more methane than previously thought. Methane has 28 times the Global Warming Potential (GWP) of carbon dioxide, so the findings indicate scientists might have to reassess how thawing permafrost will contribute to climate change.
As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.
To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.

Humans have known since ancient times that silver kills or stops the growth of many microorganisms. Hippocrates, the father of medicine, is said to have used silver preparations for treating ulcers and healing wounds. Until the introduction of antibiotics in the 1940s, colloidal silver (tiny particles suspended in a liquid) was a mainstay for treating burns, infected wounds and ulcers. Silver is still used today in wound dressings, in creams and as a coating on medical devices.
