Well if you agree with Greta, that the situation is so dire, the Coronavirus has done far more than she ever has to reduce pollution.
Well sure.. The reality is that the Coronovirus is a lot more scary than Greta.
For all intents and purposes, humans are great at reacting to immediate threats that are tangible, and where you can see the impact, but we are terrible at reacting to things which are slow in being manifested.
You can see this in every aspect of our lives. Smokers are ok with each puff of cigarettes they take, even as it helps them inch closer to cancer. After all, they get up everyday and feel ok, they can eat, go to work, enjoy their lives, all is seemingly well. But as soon as pain hits, and they feel the impact, now it's "all hands on deck", immediately stop smoking, change their diet, and do everything they can do reverse it. Why didn't they do it when they had the chance?
It will be the same with climate change. You get up, it's cold outside, how could there be climate change? You can still eat well, watch tv, go out, take vacations, buy a new car... so you kick the can down the street.
But once the oceans rise enough that some cities become unlivable and causes massive displacement of population, or when weather patterns change, and once fruitful growing areas slowly become deserts, then you can bet that even the most delusional skeptic will have to bow down to science, and beg government to implement policies that will reverse the course the history at a time when it'll be too late to do it.
