In the garden there aren't as many insects anymore. They're in decline worldwide.
The weather isn't how it used to be when you were growing up. It's hotter, colder, harsher.
We are inundated with articles about the collapse of nature- how half the animals that existed in 1970 are now gone, the coral reefs are dead, and there is no end in sight. We are adding yet more people every day.
It's very easy to fall into despair that regardless of what you do today the collapse we are careening towards will erase all of it and more.
