The sun is the source of all energy on planet Earth and we cannot experiment with our only energy source.

Changing an economic system that is bent on uncontrolled and poorly measured economic growth and depends on fossil energy for its main objectives, is much more difficult than changing how nuclear energy is used for military purposes. Some think it may be impossible.

We know little of the consequences of the geoengineering process, such as spraying particles into the atmosphere that shade the planet from the sun's rays and could decrease its temperature. But this process is how dinosaurs disappeared from the Earth about 60 million years ago, by particles spewed by a volcano or a giant meteorite impact, and our species could follow suit.

We are in the midst of the 6th largest extinction event in the history of the plant and the first caused by human action.

The transformation of capitalism is unstoppable because we need limits on resources for humans to survive.

We need to support our future instead of undermining human survival. Let's do it.

The change in economic values created by the new markets for global public goods will reorient our global economy and under the right conditions can usher the satisfaction of basic needs of the present and of the future. This is what is needed right now.
