first get a lot of information from independant sources, why not, it can even be fun!?!!!
and the you could even look at this:
BBC: "How to stop the global food crisis"
It's totally up to you now, it's a new world and you can be as intelligent or as poorly reacting as you wish. Decide for yourself, be confident that you will make the best choices if you gather a lot of information.
Use the best tool ever: Your brain!
