WASHINGTON (AFP) - About three-quarters of Americans believe the United States must lead the way in controlling greenhouse gases and pollution to fight global warming, a poll showed Tuesday.Seventy-one percent of 1,052 adults surveyed by the Harris Interactive polling service said global warming was already affecting the planet.
And eight in 10 of those polled said that as the world's leading industrial nation, the United States should take the lead in combatting the problem.
Some 87 percent agreed with the statement that "emerging countries such as India and China will soon pass the United States as the largest contributor of greenhouse gases".
The same number said climate change was a global problem and should be tackled by industrial countries working together.
Slightly more than half those polled -- 53 percent -- said there was too little government regulation in the area of environmental protection in the United States.
The poll was conducted by telephone between October 16 and 23.
