Agriculture
While the consequences of greenhouse gas emissions almost toward all the aspects of lives, the impact on agricultural production is likely to be particularly important. For example, the increment of temperature and decrease of precipitation has caused China a lower production of rice, wheat, and maize. On the opposite, China’s cotton production has increased. All these data technically does not responsible for the new technologies and new policies. “According to the World Resources Institute’s Climate Analysis Indicators Tool, the emission of greenhouse gas from agricultural sources constituted 15.4 percent of China’s total emission in 2005, behind only electricity, combustion, manufacturing, and construction”. The main component of the emission that is coming out of the agricultural industry is nitrous oxide. The data indicates that agriculture has taken up a big portion of greenhouse emission in China, therefore, mitigating the agriculture emission has recently become the very first step to solve the problem. The main effect of overdosing greenhouse gas emission is the fact that it changes the global temperature causing dramatic climate changes. These changes sometimes can shift the time of season backward or frontward. Season changes can also affect crop productions from time to time. Some crops such as wheat and corn, heavily rely on season changes and temperature variations. With the change in temperature, it is both hard for farmers and crops to grow and harvest. Now the effects of climate change may not seem too obvious, are momentous and have become larger and larger each year.

Impacts
China’s agriculture sector is almost responsible for one-fifth of China’s total greenhouse gas emissions. While it is a significant amount, the main source of agricultural greenhouse gas emission is coming from the application of fertilizer. Other sources include excrement burning or pasture management are not as many as the fertilizer. Another element of causing greenhouse gas emissions in the agricultural sector is methane. It mainly comes from livestock corpse and farm management. .

In some studies, accounting for the benefits of CO2 fertilization reduces the negative impacts of climate change on crop yields in a projected increase in yield. For example. the use of CO2 fertilization increases the production of most crops. Estimation of climate change's impacts on crop yields differs on a large scale depending on CO2 fertilization effects. However, this is not always the case. When a considerable CO2 fertilization effect is taken into account, yields actually increase except some crops such as rice and corn.

China's grassland has faced a higher temperature situation in recent years, hence the drought is becoming more and more severe. The productivity of grassland has been low. In the future years, drought will be developing at a faster pace, and this phenomenon will remain the same or even worse on the farm unless China's government begins to adapt and make changes. Even though CO2 fertilization aggravates the scenario of greenhouse gas emissions, the method does have a significant impact on the production of crops.

Improvement
In order to improve the situation of pollution and climate change, China has made a huge step toward changing the environment. It will begin implementing projects to prevent agricultural source pollution such as water contamination and soil contamination. What's more, farmers, like the government, can use different methods for their farming system and irrigation system as well. For example, farmers have switched to use groundwater to maintain or improve productivity.

Conclusion
Many studies show that climate change does have a severe impact on agriculture, primarily on crop yielding. The extent of the changes in yields highly depends on crops that are using CO2 fertilization. Some crops, therefore, increase the production due to the CO2 fertilization, but the method itself does have some severe impacts on climate change. The crop that relies on natural methods does not get the benefits at all because the climate is affected by CO2 fertilization. This level of tradeoff and balances depends on the China government and farmers. China's government needs to takes action as soon as possible in response to climate change.
