Not long ago the movie 2012 came into screen. The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster. Luckily, they are just the director’s imagination, but the present situation is not heading a positive direction, either.

Take my own experience in Alaska as an example. Once I took a trip to the glacier. Along the way there stood signposts marking the snow lines of different years. They started from the foot of the mountain, but it was at the top when I finally saw melting glaciers(融化的冰川). My heart ached seeing the beautiful blue ice melting at every second.

Sad but true, they are the effects of global warming and the result of our human impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the en tire Italy. According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.

Our fortune is in our own hands. It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let recycle become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it' s to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoid destroying them．

In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home. It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality．

Unless we spend money to spot and prevent asteroids now，one might crash into Earth and destroy life as we know it，say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one，the scientists say，we'll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “If we don't take care of these big asteroids，they'll take care of us,” says one scientist. “It's that simple.”
The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.
