"Grant me the serenity to accept the things I cannot change,
The courage to change the things I can,
And the wisdom to know the difference."
Climate change freaks me out too. There is so much that needs to be done, and sometimes it seems like no one else is paying attention. Future generations are going to look back at this as the biggest issue of our time, and marvel at how completely we dropped the ball on it. But this is not something any one person can fix. At some point you have to accept that there is only so much you can do and some things are out of your hands. You need to focus on the things that are within your control. It will not only make you feel better, when you act on the things you can control, you do increase your area of influence gradually and over time.
