My topic for the project ... FOOD ADDITIVES !!!

Food additives was my number one choice for this quarter's project. The reason was because during class, so many new informations came up during the dicussion. I didn't know the cheese that I've been eating for all these years can be considered to be "plastic"...WTH??? I rarely becomes excited over research paper but this time, I actually want to find more information on this. I also wanted to know how food additives contribute to the destruction of our environment, like during the process of making the cheese for example. I also would like to find out more about the alternatives to food preservatives/additives that can be healthy and good for our health and may be, keep our food fresh at the same time. I want to make some comparisions to foods with additives and foods without them, and see the effect on the product. Also, I'm very curious about how food additives might relate to the development of cancer. It might be a bit off topic since we are mainly focusing on environmental sustainability but I thought it wouldn't hurt anyone to just throw the idea out there.
