The best way to prevent cancer and fight it

The best way to prevent cancer and to fight it is by growing food and vegetables without the use of pesticides, and fertilizers. Studies have shown from the BBC that butterflies are disappearing as a result of pesticides, and other chemicals that are used by farmers. If we remove the chemicals from our foods, then we will be able to grow natural foods that are not tempered by chemicals. They will also not have the chemicals that make us sick with cancers and other diseases. Even milk, and rearing of chickens and cattle should be done naturally.  Researchers and the government should not just put an assault on the additives and flavors that are put on foods all the time because the issue of cancer has not stopped ever since they decided to take action, but has continued to harm our society.
