We now have access to so much information that we can find support for any prejudice or opinion.

From year to year, environmental changes are incremental and often barely register in our lives, but from evolutionary or geological perspectives, what is happening is explosive change.

We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.

We humans have become dependent on plastic for a range of uses, from packaging to products. Reducing our use of plastic bags is an easy place to start getting our addiction under control.

The current economic system is fundamentally flawed and inevitably destructive.

Wind power, if not properly planned and sited, can harm birds and bats (although Danish studies of 10,000 bird kills revealed that almost all died in collisions with buildings, cars and wires; only 10 were killed by windmills). Alternative energy sources are absolutely necessary. Global warming will kill birds and bats, as well as other species, in much greater numbers than wind power.

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.
