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.

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.

Many scientists and economists also say putting a price on carbon through carbon taxes and/or cap-and-trade is necessary.

I see a world in the future in which we understand that all life is related to us and we treat that life with great humility and respect.

We must pay greater attention to keeping our bodies and minds healthy and able to heal. Yet we are making it difficult for our defences to work. We allow things to be sold that should not be called food. Many have no nutritive value and lead to obesity, salt imbalance, and allergies.

It's not unexpected that shooting massive amounts of water, sand, and chemicals at high pressure into the earth to shatter shale and release natural gas might shake things up. But earthquakes aren't the worst problem with fracking.
