The link above is an article about what we are going to do when there is about 9 billion people living on Earth.  I was trying to figure out if GMOs were going to take a leading role in how we are going to feed everyone, or if getting rid of GMOs would be the solution.  The article is saying how all the best scientific technology out there should be used to fix this problem.  They mention that they want to educate the public more about GMOs and view it from a positive point of view on how they can contribute to feeding the growing population.
