The ethos of Republicanism is selfishness. They don't care about anything that isn't going to benefit them directly. The older they get, the less they care about the future of the planet
How about the future of their grandchildren? The older and selfish Republicans should care about the future of their genes. Those genes depend on the future of the planet.
Some people (I am not going to look for direct quotes of various forums and such) were talking about this as if they were saving "the planet". Something along the lines of "we have to save the planet from evil humans".
Humans are not only causing climate change, they are causing a mass extinction event. I feel sorry for all the plants and animals dying because of us. I'm not talking about saving the whole planet. I'm talking about saving the planet's other living things besides humans. Many species are in danger of being wiped out.
Leveraging always beats prototyping.
