If they fail to do so, we will continue with our current problems. It is not up to me. All I am able to do at this time is to present a possible alternative. The future of sustaining our species depends on the actions we take today.

I feel that I have advantages greater than Da Vinci’s such as access to more information, materials, and methods.
