Geoengineering means changing the Earth's fundamental large-scale processes.

If nuclear warfare is believed to be somewhat controlled, then climate change is now the greatest threat.

Changing the world's oceans to increase their uptake of CO2, as other geoengineering solutions propose, is equally dangerous, as the increased resulting acidity of the oceans kills tiny crustaceans, such as krill, that are the basis of the pyramid of life on the planet as we know it.

To survive, humans need food, water, and air. Yet biodiversity, the Earth's bodies of water, and the planet's atmosphere are all under threat.

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

Trees and clean energy [are] the long-run solution but we have no time to wait for the long run. We need a short-run solution now, and one that encourages and facilitates the transition to the long-run solution.

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