This is a National Science Foundation newsletter from 2009, it says Bill and Melinda Gates Foundation gave the NSF $50 Million. This is old news but $50 million goes a long way.

Now, does this explain why Bill Gates has been buying up all the farm land?
Fair warning, better start growing your own food or you will become a lab rat in the next Bill Gates research experiment.
To me it was blatantly obvious why Gates was buying farmland. My first question after Gates made headlines for buying up farmland was "does he have interest in Monsanto?".. Of course he does.
