Almost all America celebrated when Amstrong landed on noon and said, “That’s one small step for man, one giant leap for mankind,” which symbolizes the advent of the space age. People began to dream of traveling through the galaxy.
Now, many environmental problems are deteriorating: green effect, El Niño, acid rain, ozone depletion. Scientists observe the drawback of glaciers and predict that iceberg will melt out owing to the green effect, and some land will be drowned. Therefore, some major countries signed Kyoto Protocol to cooperate in reducing emissions of green house gases, such like carbon dioxide, methane, but it seems to be failed.
On the other hand, some people dreams about seeking other planet which is suitable for us to dwell in. They think the universe is so ‘endless’ that there must be some planets like earth where we can dwell. So many countries launch spacecraft to outer space not only to seek new planets but also to make some profound research for our known planets. It also can be widely known that they are the leading countries of the world.
But I think it is a little ridiculous. If you want to go to the outer space, you should have a space craft. But it need much energy and cost a lot. There isn’t so much energy resources on the earth for “all” of us to go to the other planet. I think the real way to manage the problem is to save the energy resources and reduce pollutants right now.
Every creature in the ecological system is closely linked, and what we do is deeply influenced the environment. I think deteriorating environment will contribute to the irregular precipitation, and someplace will be lack of water, than we may want to establish a reservoir. But a reservoir should need a big place to build up, so the primitive forest of a mountain may be destroyed, then the vicious circle initiates.
So everything on the earth (even in the universe) is a “ whole one”. We are the one.
We had better take care of everything around us, save the resources and reduce pollutants right now. Thus, the earth will be an eternal wonderful planet.
Armstrong had a lapse, he missed an ‘a’ in the sentence. It should be “That’s one small step for a man, one giant leap for mankind.”
