“When the symbol gets bigger than the region itself and people don’t realize that the polar bear is just one piece of a whole diverse web of life in the Arctic, then it can become almost a barrier.”
New research suggests it’s possible to have too much biodiversity. In lab tests, scientists in Switzerland showed elevated levels of biodiversity can destabilize ecosystems under certain conditions.
Over two weeks in late October, governments will meet in Hobart, Australia, to decide whether to create a vast Antarctic Ocean Sanctuary, covering almost two million square kilometres. If it goes ahead, it’ll be the largest protected area on the planet.
A study published Tuesday (Oct. 16) in the journal Environmental Science and Technology found microplastics in more than 90% of the packaged food-grade salt—also known as table salt—for sale in stores. The team, from South Korea’s Incheon National University and Greenpeace East Asia, sampled 39 brands of salt harvested in 21 countries. Only three of the samples had no detectable microplastics.
Rising acidity levels in the world’s oceans are disrupting the shell-making abilities of the marine gastropods. According to a new study, the shells of triton shell sea snails are smaller, thinner and less dense in regions where acidity levels are accelerating.
When an Austrian real estate development company was commissioned by the government to renovate the University College of Teacher Education in Vienna, it faced a problem.

The world must invest $2.4 trillion in clean energy every year through 2035 and cut the use of coal-fired power to almost nothing by 2050 to slow the quickest pace of climate change since the end of the last ice age, according to scientists convened by the United Nations.
