According to the experts, more than 17,000 plants and animals are threatened with extinction because of human activity, mostly through habitat loss. This includes 12 per cent of all known birds, nearly a quarter of known mammals, and a third of known amphibians. Climate change is predicted to sharply increase the risk of species extinction within our own children's lifetime. According to the Intergovernmental Panel on Climate Change, 20 to 30 per cent of plant and animal species assessed will likely be at increased risk of extinction if global average temperatures continue to rise with escalating emissions of carbon pollution.
This wildlife crisis has been described as a silent epidemic by scientists like famed Harvard entomologist E.O. Wilson, because it receives so little attention from governments. The David Suzuki Foundation recently released a study of government records showing that nearly half of all known wildlife species in British Columbia are at risk, including grizzly bears, caribou, and orca whales. Yet, B.C. has no endangered species law to protect its wildlife and habitat from logging, mining, urban sprawl, and other human activity.
Canada has a federal endangered species law, but the government is dragging its feet on implementing it. As a consequence, some wildlife populations, like the northern spotted owl in southwestern B.C., have declined precipitously under the watch of our politicians and are now on the verge of extinction in Canada.
The unsettling events of recent weeks reveal the inherent vulnerability of wildlife to sudden and dramatic population declines, often as a result of natural causes. This is all the more reason to ensure we don't exacerbate the challenges faced by wildlife in an increasingly busy world. We need to reduce the environmental stressors that we impose on wildlife, so that they can better cope with and survive the challenges they face every day. We need to eliminate dangerous pesticides and other toxic materials, protect the habitat of endangered plants and animals like caribou, and get serious about tackling climate change.
It's good that people are concerned about the recent animal die-offs, but if we really care about the future of wildlife, we need to start paying more attention to our own role in the extinction crisis - and urge our elected officials to take concrete steps to protect the biological richness with which our planet is blessed.

Well said by ds once again - but who is listening? just the converted few? so many people just don't care, or care in a distant sort of way,as long as it doesn't affect them directly. as long as humans keep spreading out and gobbling up land, animals will go extinct.
ReplyDeletechange is slow, but so are glaciers. a few of us in the west know everything is interconnected (which is why, when you pack a suitcase and you stuff a sock in the left, something squeezes out on the right).
