. And produce this amount will strongly affect the medium environment to enhance the greenhouse effect.
Scientists who came to such conclusions in addition, believe that it is necessary to change the way in which agriculture is practiced to meet food requirements to protect the environment. Their findings were published in the journal Proceedings of the National Academy of Sciences.
“the gas emissions of the greenhouse effect generated by agriculture could double by 2050 if current trends continue in the global production of food.” “This could be a major problem because agriculture already causes a third of greenhouse gas emissions”, explains David Tilman, ecologist in charge of the investigation has been done at the University of Minnesota, United States.
Methods more green
the specialist explained that the level of global demand for food is what determines how expands agriculture and, therefore, the pollution to the environment. And Tilman considers that it is possible to avoid the problems that would bring an increase in the demand of food if developing countries begin to use techniques that already take advantage at the first world Nations, that achieve a higher performance of the Earth.
The use of nitrogen fertilisers would also help to alleviate pollution, said Tilman.
“Strategically increase the production of crops in developing nations and the lagging would reduce the overall environmental damage caused by the production of food, and would provide a fairer amount of food around the world,” said Jason Hill, another environmentalist who participated in the research.
Tilman argued that if the first world Nations to help developing countries to incorporate more modern agricultural practice development 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.”
