Double in less than 40 years the world demand for food

Scientists who came to these conclusions also believe that it is necessary to change the way in which agriculture is practiced to meet food requirements to protect the environment. Its findings were published in the journal Proceedings of the National Academy of Sciences.

“The gas emissions of the greenhouse effect that generates agriculture could double by 2050 if current trends continue in the global production of food.” “This could be a major problem because agriculture already cause one-third of greenhouse gas emissions”, explains David Tilman, ecologist in charge of the investigation has been done at the University of Minnesota, United States.

the specialist explained that the level of global demand for food is what determines how much expanding agriculture and, therefore, the contamination to the environment. And Tilman considers that it is possible to avoid the problems that would bring the increase in the demand for food if developing countries start using techniques that already take advantage in the first world Nations that achieve increased performance of the Earth.

The use of nitrogen fertilizers also help to alleviate pollution, said Tilman.

“Strategically increase the production of crops in developing countries and the less developed would reduce the overall environmental damage caused by the production of food, and would provide a more equitable worldwide amount of food,” said Jason Hill, another ecologist who participated in the investigation.

Tilman argued that if first world Nations to help countries in developing to incorporate more modern agricultural practices, then the amount of land used for planting will be reduced. “Our analysis – ensures Tilman – shows that we can save most of the Earth’s ecosystems to help poor nations of the world to feed themselves.”
