Plankton has not been the same since the Industrial Revolution | Science

[ad_1] As scientists struggle to understand how ocean warming will affect the world's marine ecosystems, from bleaching coral reefs to modified migration routes, one of the most ubiquitous organisms in the sea is helping researchers measure changes. already occurred. Centuries of fossil recordings and live animal catch data show that some marine plankton populations reflect … Read more

Illegal gases depleting the ozone layer have been attributed to dishonest factories in eastern China

[ad_1] Industries in northeastern China have released large amounts of ozone-depleting gas into the atmosphere, in violation of an international treaty, according to scientists around the world. And this slows down the recovery rate of the hole in the crucial layer of ozone. The ozone layer is a region of the Earth's stratosphere that acts … Read more
