Environmentalists Use Oil Spill as a Rallying Cry
By KATE GALBRAITH
AUSTIN, Texas — The oil spill spreading through the Gulf of Mexico has been declared the worst environmental catastrophe ever in
the United States. But for American environmentalists, the distress may also bring opportunity.
An environmental group, American Rivers, is anticipating more attention to wetlands issues in general, even though oil was spilled
into the sea, not rivers. “People are simply more tuned into environmental issues right now, especially when it comes to clean water,”
said Amy Souers Kober, a spokeswoman for the group.
There is a flip side, however: other environmental causes could get starved of money and attention. For the past 50-plus days, the oil
spill has dominated the headlines, the news programs and even the comedy shows across the United States (the comedian Stephen
Colbert recently suggested that the Gulf of Mexico be renamed the Black Sea). Other issues could get overlooked.
The Obama administration has tried to tackle climate change, but as for the other treaties, even if it were interested in moving
forward, it would be tough because so much of the administration’s time is now consumed by the oil spill. From the public’s
perspective, even pressing issues — like the International Whaling Commission’s coming vote on whether to allow some commercial
whaling — have largely been lost in the noise.
In some ways, the focus on the spill over the past two months has paralleled the constant attention to climate change over the past
several years. In 2005, the Sierra Club, a leading American environmental group, decided to switch its attention more fully to
climate, and most other groups have also increased their attention to the issue.
But climate change has the potential to affect just about everything — and it has conversely afforded a range of groups the
opportunity to hitch their causes to the climate bandwagon.
As for the spill in the gulf, Mr. Plater of Boston College suggests that it may become a “wake-up call” for environmental causes across
the board.
The issue of climate change is mentioned in this article.
(a) What is climate change? (2 marks)
(b) What is causing climate change? (3 marks)
(c) Give some EVIDENCE from the present and from the proxy record that proves
climate change is actually happening. (4 marks)
(d) The article states that “climate change has the potential to affect just about everything”. What
is meant by that statement? (2 marks)
