The reason the rich don't care about pollution, and seem to make exclusively shortsighted plans is because of prisoner's dilemma.
Between climate change, automation replacing meatworkers, and dwindling resources amid a growing population (peak oil is passed, peak farmland passed, peak phosphorus and water soon to follow), they know that at least one of these will bring about a societal collapse and that nothing short of a worldwide united effort would even have a chance of preparing for all of them. Job death can be fixed with welfare but 1. who of the rich is willing to pay for 7 billion pet humans? and 2. even if they were dwindling resources make them unable, while climate change accelerates the loss.
Meanwhile, anyone who throws the rest under the bus for a last minute scramble for top dog will have a much higher chance of having the control and means to survive. The goal is to put as much economic space between yourself and them below as fast as possible. You may not need more now, but the deadline is vague and you want as little competition as you can, by having no peer or killing any that were.
You can see pretty easily in each businesses' model which choice they're making, and how they intend to handle issues when they arise.
Take Elon Musk for instance. He's investing in mainly three technologies. Clean energy, pushing back the climate change deadline which could ruin his plan, artificial intelligence, which if discovered by the wrong hands first could ruin his plan, and space travel.
If you're having a hard time figuring out where that last one fits in, think of what happened with Britain when the land was overpopulated with debtors. Mars is new USA. You solve the teeming throngs with no jobs eating all of the riches' resources by having them colonize the new world. First by promise of prosperity, Then through debtor colonies.
Others obviously have a plan of either a slow death for us through starvation and disease or a quick purge.
