有关“自然、环境、生态”方面的佳句

以下是自然、生态、环境方面的佳句
1Pollution is, in fact, threatening our existence.
2Villagers are as a rule healthier than people who live in towns. One reason for this is that country air is fresher than the air in smoky cities.
3Most of the noise in the city comes from traffic, factories and construction sites.
4There is an increasingly loud voice from the public calling for firm action against pollution.
5Scientists have warned that unless effective solutions are worked out, the problem of pollution will eventually get out of hand.
6Many factories discharge enormous harmful chemicals into air and rivers every day.
7To kill insects, farmers use a large amount of insecticides so as to have a bumper harvest. As a result, they pollute the air, water and land.
8The gas from car engines is very poisonous. It is a main source of air pollution in cities.
9Deforestation result in the increase of global temperature and unpleasant change of climate.
10The earth is our home and we have the duty to take care of it for ourselves and for our later generation.
11Beijing now has become one of the most polluted cities in the world. Among the 10 cities with the worst air pollution in the world last year, Beijing was the third most polluted city.
12If the city had not plagued by poor quality air, the annual death rate in Beijing would have been 4 percent lower in past three years, according to the research done jointly by Beijing Medical University and Harvard University.
13Beijing consumes 2.8 million tons of coal each year, of which 75 percent are low-grade coal.
14To make room for those buildings, trees are being cut down, grass plots occupied. Cities look like nothing but grey concrete woods.
15Modern cities should be expanding with a certain percentage for green-plant areas.
16We must begin now to protect our only earth.
17Almost everything we use daily comes from the land directly or indirectly.
18But the limited land is decreasing at a surprising speed.

it is really worth reading. 4# shanghongbin
