A HEALTH CHECK FOR THE WORLD
Nature provides us with everything we need to live, from the air we breathe, to drinking water, food and all the resources we use to make things, and to power our homes, cars and factories. However, all over the world we’re cutting down forests, using too much water from rivers, depleting the oceans of fish and pushing some animals to extinction.
For the last 20 years, scientists have been measuring changes in the populations of thousands of animal species around the world, from counting the number of wildebeest in the savannah, to using cameras to track the movement of tapirs in the Amazon rainforest.
They have also looked at changes in where different species are found and their risk of extinction. Sadly, WWF’s latest report concludes that wildlife populations are disappearing fast, leading to a decreasing variety of life on Earth.
