If you added up how much nature would charge for these free services and compare it to what humans produce and the services they provide, it would amount to 500,000 times as much per year.
However, nature is increasingly being destroyed, for instance, through deforestation of rain forests, the straining of the environment or through the overuse of fertilizers and toxins. This is a big threat to biodiversity.
Every day, up to 130 animal and plant species become extinct! Of the 2 million species currently known, 41% (820,000) are endangered.
Therefore there are many positive ecological, economic, social, and ethical reasons why biodiversity should be protected and preserved.
