Em leitura: A Grande Aceleração

  «Biodiversity conservation has become a global norm in a very short period of time, in reaction to mounting evidence of biodiversity decline. Despite real conservation successes, human activities since 1945 greatly intensified the number and severity of threats facing the world’s living organisms. Human beings increasingly order the world. We have selected a handful of preferred plant and animal species, living in managed and simplified landscapes, and have unconsciously selected another handful of species that adapt well to these landscapes (rats, deer, squirrels, pigeons, and such). In so doing we have greatly reduced or eliminated the number of other plants, birds, mammals, insects, and amphibians that lived in and on these landscapes just a short time ago. In this regard the ethical question is much the same as ever: Are we content with a world containing billions of humans, cows, chickens, and pigs but only a few thousand tigers, rhinoceroses, polar bears - or none at all?
The twenty-first century portends still greater pressure on biodiversity than did the twentieth.   Rising affluence, at least for some, plus three to five billion additional people, will menace the world’s forests, wetlands, oceans, seas, rivers, and grasslands. But climate change likely will set the twenty-first century apart.» (pág. 100)
