Because we aren't certain about the effects of GMOs, we must consider one of the guiding principles in science, the precautionary principle. Under this principle, if a policy or action could harm human health or the environment, we must not proceed until we know for sure what the impact will be. And it is up to those proposing the action or policy to prove that it is not harmful.

Other things, like capitalism, free enterprise, the economy, currency, the market, are not forces of nature, we invented them. They are not immutable and we can change them.

There is a gyre of discarded floating plastic the size of the continental USA in the ocean. In it, plastic trash outweighs plankton 40 to 1.

The environment is so fundamental to our continued existence that it must transcend politics and become a central value of all members of society.

I can't imagine anything more important than air, water, soil, energy and biodiversity. These are the things that keep us alive.

There are some things in the world we can't change- gravity, entropy, the speed of light, and our biological nature that requires clean air, clean water, clean soil, clean energy and biodiversity for our health and well-being. Protecting the biosphere should be our highest priority or else we sicken and die. Other things, like capitalism, free enterprise, the economy, currency, the market, are not forces of nature, we invented them. They are not immutable and we can change them. It makes no sense to elevate economics above the biosphere.

In the environmental movement, every time you lose a battle it's for good, but our victories always seem to be temporary and we keep fighting them over and over again.
