Positive And Negative Effects On China

While researching，I learned that there are both positive and negative effects .One positive effect is that it can let we have more and more plants .Another positive effect is that it can keep the ecological balance.However it has some negative effects.It destroyed the integrity of the ecology.It has some natural reasons and human reasons.For natural reasons. First, the world is in a warm period.The earth exists periodic orbit track changes.For some human factors.First ,The greenhouse effects causes global warming.There is a reason that the increasing population. Second, The forest resource is decreasing .We should take some measures .We should strengthen international cooperation.Global is involved in controlling emissions of carbon dioxide

The latest information released by the China Meteorological Administration shows that the average temperature of the Earth 's surface in China has risen by 1.1 degrees Celsius over the past century, from 1908 to 2007, that China experienced 21 warm winters from 1986 to 2007, the latter being the warmest year since the beginning.— A complex climate and a fragile eco-environment determine that China 's task of adapting itself to climate change is arduous. China is characterized by a continental monsoon climate, and most parts of China have a wider range of seasonal temperature change compared with other continental areas at the same latitude. Many places in China are cold in winter and hot in summer, and high temperatures generally prevail in the country at large in summer. Precipitation is unevenly distributed in time and space, concentrating in the flood season, and annual precipitation decreases from the southeast coast to the northwest interior. China has a fragile eco-environment, with serious soil erosion and desertification and a forest coverage rate of 18.21 percent, only 62 percent of the world 's average. The area of natural wetlands is comparatively small; most grasslands are highly frigid meadows and desert steppes.With a coastline over 18,000 km long, China is vulnerable to the adverse effects of sea level rises. — A large population and a relatively low level of economy
