Numbers and species
Out of the 8 million living species, one million are in danger of becoming extinct due to human activity. Today, the rate of extinction is one hundred times greater than it has been the last 10 million years.
In 1950, 2.3 million tons of plastic was produced and the figure rose to 448 million in 2015. This is predicted to double by 2050.
Every year, about 8 million tons of plastic waste end up in the sea. The life cycle of plastic before it decomposes can reach 400 years.
Between 1990 and 2016, the world has lost 1.3 million square kilometres of forest, the same surface area as South Africa.
Since humans began to deforest natural areas, 46% of trees have been cut down.
From 1994 until today, terrestrial glaciers have lost approximately 400 billion tons of ice per year.
Global sea levels have risen by over 20 centimetres over the last century and, over the last twenty years, the rate has doubled.
