Can We Feed the World & Sustain the Planet? A five-step global plan could double food production by 2050 while greatly reducing environmental damage

Right now about one billion people suffer from chronic hunger. the world’s farmers grow enough food to feed them, but it is not properly distributed and, even if it were, many cannot afford it, because prices are escalating. But another challenge looms. By 2050 the world’s population will increase by two billion or three billion, which will likely double the demand for food, according to several studies. Demand will also rise because many more people will have higher incomes, which means they will eat more, especially meat. Increasing use of cropland for biofuels will make meeting the doubling goal more difficult still. So even if we solve today’s problems of poverty and access—a daunting task—we will also have to produce twice as much to guarantee adequate supply worldwide.
