[...] It is a curious fact that on Earth species death is, in the most literal sense, a way of life. No-one knows how many species of organisms have existed since life began. Thirty billion is a commonly cited figure, but the number has been put as high as four thousand billion. Whatever the actual total, 99.99 percent of all species that have ever lived are no longer with us.

It's the idea that people living close to nature tend to be noble. It's seeing all those sunsets that does it. You can't watch a sunset and then go off and set fire to your neighbor's tepee. Living close to nature is wonderful for your mental health.

[Extinction of Nature Experience] from generation to generation, young people are living less and less in contact with nature

But we can easily extend this hypothesis [that nature has beneficial effects on the physical, cognitive and emotional well-being of individuals] to the conservation of biodiversity. [Ecologists] refer to the extinction of the experience of nature, which they have mainly applied in urban areas. The idea is as follows: from generation to generation, young people live less and less in contact with nature (because there are fewer of them and because their lifestyles limit such contact), at the very moment they are building their identity. The part of their identity that integrates their intimate relationships with their natural environment would therefore diminish from generation to generation. Not because of a lack of education, but mainly because of a decline in opportunities and desires to experience nature without constraint, freely and in their own personal way.

The consequences of this decrease appear in adulthood: with a weaker environmental identity, they are less in demand for nature in their daily lives, they integrate it less in their actions. (...) But if we do not collectively take biodiversity into consideration in our lifestyles, then we will suffer.
