All great suggestions!
I do however think it's still OK to do what you can (I don't think anyone in this thread has given up on Earth, or does nothing), while having a diet from the news, which like you say, even fosters the feelings of hopelessness.
I can do my part, and I can also be frustrated at those in leadership positions falling prey to powerful lobbies that represent environmentally unfriendly industries.
