Deteriorating Food Security.

The impact of climate change increasingly felt in hall comers of the wold. Floods, drought, cold and estreme sea level is increasing evidence that the impact of climate change is happening now. This situation has put human lives at risk threshold of destruction.

Climate change is affecting the severity of the linkages that affect the balance of natural ecosystems. One major impact of climate change is a global food security.

The phenomenon of global warming to be the cause of the increase in wold temperatures. As a result, the wold is populated increasingly hot and bothered human life. This situation has caused an imbalance in natural ecosystems. Climate models expect the increase in average global temperatures could occur at 1.1 – 6.4 degrees Celcius in the 21^st century.

World food resources are produced mostly from agricultural activities will receive an impact. Planting of wheat, rice, maize cereals and vegetables has deteriorated with the occurrence of global warming. Food production in 2008 of rice was 668 million tones, wheat at 118 million metric tons of corn and 772 million metric tons.

Global warming has resulted in declining soil fertility. Soil conditions are dry and arid cause farms to be cultivated not. Global water crisis that occurred were caused water shortages. This  contributed to the problems of food production. Excessive heat will push the farm and forest fires.

This is their impact on world food production. The quantity of food produced less, while the quality produced was also effected. There are some plants can grow and develop properly due to lack of water supply for irrigation purpose. In some areas. Floods and hurricanes that hit the lead farm their crops are destroyed.

Conclusion,  global warming has indirectly affected the chain of wold food security. Among the food shortages will cause will cause an increase in the number of malnourished people.
