Nature holds the key to our aesthetic, intellectual, cognitive and even spiritual satisfaction.
Each species is a masterpiece, a creation assembled with extreme care and genius.
We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity.
Biological diversity is the key to the maintenance of the world as we know it... Eliminate one species, and another increases to take its place. Eliminate a great many species, and the local ecosystem starts to decay.
If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment.
Destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal.
Biophilia: the innate pleasure from living abundance and diversity as manifested by the human impulse to imitate Nature with gardens.
Ninety-nine percent of all species that ever lived are now extinct.
The commitment must be much deeper - to let no species knowingly die; to take all reasonable action to protect every species and race in perpetuity.
