Nearly 175 countries are meeting Monday in Paris, at the headquarters of UNESCO, for a second round of negotiations to establish an international treaty against plastic pollution. 460 million tons of plastic are produced each year worldwide and less than 10% is recycled.

Two-thirds end up thrown into the environment, with catastrophic consequences for marine animals in particular, but also for human health. The summit will bring together representatives from 175 states to define the first outlines of a binding treaty on plastic pollution under the auspices of the United Nations.
