We need big-picture thinking to protect nature.
by David Suzuki
Few places on Earth have been untouched by humans, according to a study in the journal Science. Satellite images taken from hundreds of kilometres above the planet reveal a world that we have irrevocably changed within a remarkably short time.
Although industrial projects like the proposed Enbridge Northern Gateway pipeline or the recently defeated mega-quarry in Ontario typically grab the headlines and bring out public opposition, it’s often the combined impacts of a range of human activities on the same land base that threaten to drive nature beyond critical tipping points. Once those are passed, rapid ecological changes such as species extinction can occur.
