research : how to feed a planet with growing population

7 billion people on earth , how we can feed them all ?

Here's a not entertaining mathematical equation; by the year 2045 the world's population will jump from 7 to reach 9 billion people. To fill all these bellies - taking into account shifts consumption patterns, climate change, and the limited amount of arable land and drinking water - some experts argue that it requires double the amount of food production on a global level. But how we can solve this equation? Julian Crepe said in his book "The next famine", the high-yield crop items and the more efficient farming methods, will be crucial in the future; This also applies to reduce waste, Crepe and other officials who experts in the cities urges to draw nutrients and water from the waste, and to maintain agricultural land. According to these experts, the poor countries can improve store operations and packaged crops, rich countries can reduce their consumption of foods that deplete resources such as meat.

In fact, wherever food is available cheaply, people come to buy more than they consume, all we need is to start shopping more rational; without leave for one summit in dishes.and as Julian Crepe said " Food security became collectively bet, all of us should earn it. It also gives an opportunity to work with all of us to achieve something we can agree about it, share it, and enjoy it all.
