This is really a serious problem we should pay attention to ! So this topic is quite meanfulling! so net collected this essay for you!
The human race has experienced a consistent increase in population since the beginning of its history. Famine and disease have done little to offset this steady increase. Too many people are added annually to the population of the world. So both the causes of population increase and the results of having more people are worth careful study.Culture evolution is the major factor responsible for population increase. Early in human development,people invented tools to hunt animals. Later they built shelters to protect themselves. Step by step,they made life easier. As a result,fewer died from natural forces,such as harsh climate and disease.In the past,when population grew,there was unexplored territory to inhabit. But now,almost all the habitable land has been explored.
The world‘s population may reach 8.7 billion in 2033. It is clear that world population is a serious issue that needs careful attention. Human beings are unique to solve problems through cultural evolution.Facing the world population explosion in the near future. We must carry out the birth control program in order to save the mankind and save the world.
From this cartoon, we can see that at the top end of the river,
is a chemical factory and a paperrnaking factory which send out
and poisonous wastes. And the river has been seriously polluted,
n be seen from the color of it. Along this "black" river, there are
a few people selling fresh water which must have been taken from
far away places.
At the first glance, it is very strange to us how can people sell wa-
ter along the river, but this is the case, because the water in this river is undrinkable. This presents a serious social problem--environmental pollution. With the development of economy, our living standards have been greatly improved. But we can’ t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used to be. Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem.
I think we can first call people’s attention to this problem so that
they will be aware of the serious consequences of it. Then,we can pass certain laws to restrain the factories from sending out wastes. Finally, we can do more resarch work to find out ways to deal with the wastes.
Keep Square Clean, Tidy On Sunday, still on display on Tian’ anmen Square were dozens of floats that were paraded along Chang’ an Avenue during the NationalDay celebrations. Thousands of people strolled on the narrow lanes be- tween the floats that fragmented the square, busily taking photos. Not far from the noisy crowds, yellow leaves fell nonchalantly from locust trees along the driveway, sending out the first signals of the coming autumn. But even if all the leaves fall, they still cannot cover the brown and black spots on the hitish stones in the huge square.
Such stains of chewing gum, stale oil or some worse blemish have remained a constant pain for city cleaners since the square ’was re-
opened a few months ago after renovations to celebrate the 50th anni- (http://www.***.cn收集整理)
versary of the founding of the People’s Republic of China.
Few renovation project planners likely foresee this discouraging outcome. Originally, they merely intended to give the city a face-
lift. The square was indeed impeccable when new: The-white terrazzo
surface not only looks clean but it was made with materials that help
prevent it from becoming slippery.
However, as time goes by, the virtue becomes the vice: the sur-
face attracts and accentuates dirt. As a result, China’ s most high -
profile site has to suffer the indignity of being paraded daily efore thepublic in a humiliation state.
While the tourists who litter should bear the bulk of the blame, the renovation designers should also have learned something: including the square’s sanitary maintenance issue into their consideration.
The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more, every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.
