It is often said that man has become the enemy of our planet. This is no exaggeration(夸张), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.

Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.

Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外线)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.

Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.

There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（规模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.

In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.

2010 was the year the Earth struck back.

Earthquakes, heat waves, floods, volcanoes, super typhoons, blizzards(暴风雪), landslides(滑坡)and droughts

killed at least a quarter million people in 2010---the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.

“It just seemed like it was back-to-back (接二连三) and it came waves,” said Craig Fugate, who heads the US Federal Emergency Management Agency. It handled a record number of disasters in 2010.

“The term ' 100-year event ' really lost its meaning this year.”

And we have ourselves to blame most of the time, scientists and disaster experts say.

Even though many disasters seem accidental, the hand of man made this a particularly deadly, costly, extreme and strange year for everything from wild weather to earthquakes.

Poor construction and development practices make earthquake more deadly than they need be. More people live in poverty in vulnerable building (危房) in crowded cities. That means that when the ground shakes the river breaches(攻破), or the tropical cyclone (旋风) hits, more people die.

The January earthquake that killed well more than 220000 people in Haita is a perfect example. Port-au-Prince has nearly three times as many people, many of them living in poverty, and more poorly built shanties (棚户区) than it did 25 years ago. So had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80 000 range, said Richard Olson, director of disaster risk reduction at Florida International University.

Climate scientists say Earth's climate also is changing thanks to man-made global warning, bringing extreme weather, such as heat waves and flooding.

The excessive (过多的) amount of extreme weather of 2010 is a clear sign of man-made global warning that climate scientists have long warned about. They calculate that the killer Russian heat wave ---setting a national record of 111 degrees --- would happen once every 100000 years without global warning.

Preliminary (之前的) data show that 18 counties broke their records for the hottest day ever.

White House science adviser John Holdren said we should get used to climate disasters or do something about global warning. "The science is clear that we can expect more and more of these kinds of damaging events unless and until society's emissions of heat-trapping (吸热的)gases and particles are sharply reduce."
