During the last few weeks, we have been studying about staple foods and the impacts of science. I learnt that science has a huge impact on staple foods and I was very surprised to learn some facts including the scale of the pesticides business. In fact, the economy of pesticide production is a 50 billion dollar business. However, there were some difficulties such as finding a beneficial impact of pesticides on the environment as it is not that obvious. Next time, I think I should put more quotes to back up my research.
