Answer:
Most of humanity have been grossly negligent in our use of the Earth. Businesses run according to self-interest have ignored the warnings of scientists to the detriment of a global community of bystanders. Governments have failed to attend to the long-term environmental and climate effects of those actions through necessary regulation and enforcement. And urban individuals and families continue to make choices with little if any understanding of how their consumption impacts the planet and our future on it.
Our planet has experienced five previous extinction events—the most recent responsible for the disappearance of the dinosaurs. If we are to minimize the impact of growing threats to the ecological systems essential to human life and prevent the planet’s sixth mass extinction, we need to protect the last remaining areas on earth that are relatively intact.
When we say “intact” we mean those dwindling places that still retain almost complete assemblages of native plants and animals, and where species are still interacting at ecologically functional population levels. Intact places resist climate change because they have multiple, redundant networks for capturing, using, and reusing energy. They better conserve plant and animal species and their complex ecological interactions, than degraded areas, when impacted by floods, fires and droughts. They sequester massive amounts of carbon and they keep wildlife pathogens out of reach of humans for whom they pose a deadly threat.
