For this part, we pay most attention on the food security problem in Africa.
In my point of view, this big problem happens everywhere involving everyone.
See, a conscienceless food company who only cares about making money will cause trouble in food security. We are all familiar with the story of Chinese poisonous powdered milk and KFC's uncommon chicken. These are good examples of food security problems around us.
I highly recommend that we can launch a website, using the format of YELP. We consumers put a black star to some company if they treat us in a wrong way.
Every company needs a good reputation if he wants to do bigger. So let's make our own effort to build a nice environment.
