Climate Change in People’s Republic of China
People’s Republic of China, the biggest country in developing countries, developed increasingly faster than before. The GDP (7,426,090 million dollars)increased to the second position in the world-scale, following the USA. However, in contemporary society, the changes of climate also attracted a large number of people. The environment problem is a severe problem to China even to all the countries all over the world. The emission of Carbon Dioxide is a hot topic among all the countries because more carbon dioxide can engage global warming and make the sea level increase. The increase of sea level made a lot of people lose their homes and the destroy on economy was also large. The bar chart shows to Co2 emissions per year among 3 countries. Obviously, China is the largest one. As a consequence, someone said that By 2030, China’s carbon dioxide emissions could equal the entire world’s CO2 production today, if the country’s carbon usage keeps pace with its economic growth.



The high level of emissions of Carbon Dioxide in China can be associated with 3 main factors: population, the number of cars and the number of factories.

Population
People’s Republic of China has the largest population in the world so more human activities may change the climate and environment. More people may use more resources and occupy more lands so that is why the cover area of forests and grasses decreased a lot by the augment of population. The line graph shows the tendency of Chinese population. Although the government publish the birth control policy, the large basic number of population is still a burden to fast development in the age of change.

The number of cars
The CO2 emission of Road Transports accounts for 15.9% in man-made CO2 emissions.

With the fast development of economy, Chinese people’s lives are getting better than before. The income of per people every year also increased. As a consequence, an increasing number of cars go into everyone’s family. The discharge of greenhouse gas from cars occupy a large part. The line graph shows the increasing number of cars in China. The People's Republic of China has the second largest fleet in the world, with slightly more than 78 million vehicles, overtaking Japan in 2010. About 13.6 million vehicles were sold in 2009, and motor vehicle registrations in 2010 increased to more than 16.8 million units, representing nearly half the world’s fleet increase in 2010. The number of cars and motorcycles in China increased 20 times between 2000 and 2010. This explosive growth has allowed China to become the world's largest new car market, overtaking the U.S. in 2009. Nevertheless, ownership per capita is 58 vehicles per 1000 inhabitants, or a ratio of 1:17.2 vehicles to people, well below the rate of motorization of developed countries.

The line graph shows the vehicle sales from 2007 to 2012.

As can be seen from the graph, only the vehicle sale of China increased dramatically from 08 to 12. It means that the market of vehicle was expanding. Comapring with Japan or the USA, the speed of augment is very fast and dramatic. From 2007 to 2009, the sale of car in US, Canada and Mexico even decreased. However, the sale in People's Republic of China was rising in that period. In the meantime, the ratio of increasing is still higher than before. A car is a status symbol in developing countries around the world and as incomes have risen strongly. There has been a corresponding rise in car ownership in the country.

Fortunately, with the increasing of the awareness of protecting environment, Chinese government limit the number of cars on the road by dividing the odd or even numbers. That can release the discharge of CO2. Some taxi drivers also decided to use gas as the energy in order to save the cost and decrease the emission of CO2.

The number of factories
Factories can manufacture products which can be not only sold inside country but also export to other counties. People’s Republic of China is still biggest producing country in the world. “Made in China” is not just a place to make things but a brand. With the increasing of GDP and income, the factories also discharge a lot of pollutants every day. Some factories also discharged toxic air and caused acid rain. Thus, China is home to 20 of the world’s 30 most polluted cities.

Future
However, People’s Republic of China is also focusing on protecting the air. The government is trying to use clean energy and renewable energy in order to save the natural resources and improve the quality of air conditions. The government also put a large of money on developing it. The Chinese government is investing in its renewable energy industries “aggressively” and “has built the largest solar and wind production industries in the world in just a few years.”
