How Are We Going To Feed 9 Billion?

How are we going to feed 9 billion people in the year 2050?  Current populations trends point to a world inhabited by that many people.  That means by 2050 we would have added an additional 2 billion people.  Right now there are 1 billion people who go hungry every day.  A recent article in Science magazine written by nine scientists claim that we can indeed feed 9 billion people if we make some major changes in how we currently feed the world.  First off, we cannot accommodate a western style meat diet in the world to feed that many people.  Meat, and primarily hamburger, is consumed at a much higher rate in the west than in developing and eastern countries.  It does not mean moving to an all-vegetarian diet, but one that limits meat to three times a week.  If the limits are not voluntarily adopted by the west, then we would have to find a land mass the size of Brazil to grow cattle on to feed the world Fisheries are under tremendous strain with the current population and there would be a greater need to build large fish farms to handle the increase.  The scientists further argue that we would need to allow GMO’s to go big time mainstream.  Higher crop yields are the only possibility in being able to feed the growing population.  That means GMO seeds that are controlled by large corporations.  The article states that the world’s climate changes must cease in order to accommodate the additional people.  Unfortunately more people means more methane, and fossil fuel consumption.  Biodiversity would be at risk, and global temps would have nowhere to go but up.  Personally, I think we need to focus on family planning, and educating developing countries, and our own, to limit births, and move to zero growth, with an eye to reducing our numbers.  The prospect of GMO’s invading all food types, and more people do not seem like an attractive prospect for humanity.  Adding all of these people will only compound the problems that already exist in the environment.
