New research by the University of Minnesota shows that global food demand could double by 2050, while producing that amount of food could significantly increase levels of carbon dioxide and nitrogen in the environment and cause the extinction of numerous species.


New research by the University of Minnesota shows that global food demand could double by 2050, while producing that amount of food could significantly increase levels of carbon dioxide and nitrogen in the environment and cause the extinction of numerous species.

 

But the research points out that this can be avoided if the high-yielding technologies of rich nations are adapted to work in poor nations, and if all nations use nitrogen fertilizers more efficiently.

The research reveals that if poor nations continue current practices, they will clear a land area larger than the United States (two and a half billion acres) by 2050. But if richer nations help poorer nations improve yields to achievable levels, that could be reduced to half a billion acres.
