Global Warming causes Darfur Conflict?

Ever since the Darfur genocide has been known, people believed religion and ethnicity were the main cuases of the conflict, however, Faris from Atlantic magazine asserts otherwise.

He believes conflict in Sudan is caused by global warming.

Before the global warming dried off Sudan, the African farmers in Darfur were amicable to Arabs who mostly herded flock for their living; farmers in Darfur allowed Arab to pass their land to graze their flock. However, due to global warming, drought became prevalent and Arabs were no longer welcomed to pass farmer's land. The drought did not spare room for hospitality anymore. Even among the farmers, there were constant conflicts to gain access to water. So, the group of Arab nomadics who were left "landless and desperate" started to fight against Africans in Darfur to acquire lands for themselves.

The global warming yields competition for living and competition leads to hostility. Although, this unexpected cause makes all of us responsible for the Darfur genocide, there are so many who are still oblivious of horrible crisis in Sudan. Now it is time for all us to fianally cooperate with decisive attitude to resolve this horrible conflict. Every time we take actions to stop the global warming, we are not only saving the earth, but also saving millions of innocent lives in Sudan.
