In an informative essay, describe the effects of globalization on air pollution in china's largest cities.

Globalization is a term that relates to businesses operating on a worldwide scale as opposed to just locally. This is possible due to modern transportation and technological advancements. Each country has different  resources and skill sets to produce goods and services. The goods and services chosen are typically based on comparative and absolute advantages which determine what countries can produce what goods and services with the least effort. However, the increase in production has negative effects on  the environment as a result of the process causing pollution.

In the last 30 years, China has risen to the top as the world's largest nation. In fact, China has resulted in over 400 million people rising above the poverty line which can never be repeated. In all this China has effectively become the "factory of the world". Large economies were developed in cities like Shenzhen, Tianjan, Shanghai, etc. There were hundreds of factories clustered together. These factories made lots of mass produced items to be exported all over the world. Within the country itself, this has led to increasing problems of pollution because millions of trees had to be cut down to make space for  business buildings and factories. This led to decreasing oxygen in the air. After this, the increasing cars, fumes in factories, ac units, ect contributed to the rising temperatures and pollution in the air. Increased consumption leads to an increase in the production of goods, in this case it puts stress on the environment. Globalization causes rise in the amount of fuel that is consumed in transporting these products has led to an increase in the pollution levels in the environment. Seventy percent of chinese households burn coal or biomass for cooking and heating, which contaminates  indoor air.  

In conclusion, Air pollution will remain a serious problem in China as long as factories are being used, businesses keep being built and trees cut down, and coal continues to be the country's major energy source.  In the last 30 years, China has risen to the top as the world's largest nation. The cities are becoming extremely hot due to the added pollution as their population grows.There were a lot of factories clustered and these factories made lots of mass produced items to be exported all over the world. Within the country itself, this has led to increasing problems of pollution because millions of trees had to be cut down to make space for  business buildings and factories.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
