The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge, and there’s no place for it in the endeavor of science.
Our generation must choose. Which do we value more—short-term profits or the long-term habitability of our planetary home? The world is divided politically, but ecologically it is tightly interwoven. There are no useless threads in the fabric of the ecosystem. If you cut any one of them, you will unravel many others.
If we ruin the Earth, there is no place else to go. This is not a disposable world, and we are not yet able to re-engineer other planets.
