You should find solitude in the fact that we might be the only species who actually have a chance of not becoming part of that statistic which we do by making the planet much more hospitable for us than life used to be. We do this by creating new knowledge which we then use to turn useless materials into valuable resources which allow us to solve problems that have always been challenging us.
So go on live your life, eat, travel, create, consume. Don't worry about the catastrophist rhetoric, don't worry about going vegan (unless you want to), don't worry about your CO2 footprint or any other things other people want you to care about for their own political ideologies.
Be optimistic and worry about living a good life, with good people, doing good and meaningful things and if you have the skills maybe get into something valuable like coming up with how to create more powerful energy forms such as fusion.
