We get use to convenience, and large companies capitalize on it. We expect these companies to offer implied guarnatee that their products are safe for consumption. And, we tend to expect that the government (local, state, and national) tell us which companies are ethical, failing to realize it takes lots of revenue to hire folks to do the compliance examinations.
We now know that the giant agricultural companies that produce GMOs use millions of tons of chemicals because of our monetary support. As long as we continue to purchase their products they will continue to pollute the environment and our bodies.
We can stop them on their tracks by not supporting these companies with our dollars; and we can support those companies that do not use GMOs for ethical reasons.
