下面带着对这些单词和短语的理解，尝试读一读下面的原文，看看是不是容易理解的多了呢？

In the Himalayas, the third largest mass of ice: at the top you see new lakes, which a few years ago were glaciers. 40 percent of all the people in the world get half of their drinking water from that melting flow. In the Andes, this glacier is the source of drinking water for this city. The flows have increased. But when they go away, so does much of the drinking water. In California there has been a 40 percent decline in the Sierra snowpack. This is hitting the reservoirs. And the predictions, as you've read, are serious.

This drying around the world has lead to a dramatic increase in fires. And the disasters around the world have been increasing at an absolutely extraordinary and unprecedented rate. Four times as many in the last 30 years as in the previous 75. This is a completely unsustainable pattern.

In the last five years we've added 70 million tons of CO2 every 24 hours -- 25 million tons every day to the oceans. Look carefully at the area of the eastern Pacific, from the Americas, extending westward, and on either side of the Indian subcontinent, where there is a radical depletion of oxygen in the oceans. The biggest single cause of global warming, along with deforestation, which is 20 percent of it, is the burning of fossil fuels. Oil is a problem, and coal is the most serious problem. The United States is one of the two largest emitters, along with China. And the proposal has been to build a lot more coal plants.

But we're beginning to see a sea change. Here are the ones that have been cancelled in the last few years with some green alternatives proposed. However there is a political battle in our country. And the coal industries and the oil industries spent a quarter of a billion dollars in the last calendar year promoting clean coal, which is an oxymoron. In my home in Tennessee, a billion gallons of coal sludge was spilled. This, is the second largest waste stream in America.
