A study by the UN "Global Perspective on Biodiversity" warned
about the impact of human beings on Earth on basic resources such as water and
food. According to the director of the study, humans can not live without
biodiversity.
A quarter of the plant species may become extinct and increasingly
shrinking are the tropical forests, the habitats of dust, etc..
The Secretary General of the UN said that biodiversity provides an
effective ecosystem from which we get food and water.
If we do not act in time, we will be in danger.
The causes of biodiversity loss include climate change, pollution and
overexploitation of resources.
