Sobering.
For myself, I find I can rarely just walk away from information like this. So, years ago, because of my Permaculture training about beneficial critters and then continuing with what I see in my own yard, I started letting wild islands come up around the place.
Wild islands are little areas (or big ones ) that volunteer, with mostly native plants and fungi. The soil is not disturbed, and the plant material is left standing in autumn and over winter. Just nature.
Since several wild islands have been in place, I have seen more songbirds, more types of songbirds, more types of beneficial insects, in larger numbers, and far fewer pests. Just my yard, yes, but there are millions of people on this continent with yards.
A local community organization is letting me convert lawn to resilient gardens and mercy, the improvement is so fast, once you direct and hold rainwater in appropriate places, and pile on the wood chip mulch! Bees, birds, and the soil has come alive! There was one incident of fall web worms on a mulberry. A little diluted dish soap did them in, and the mulberry kept on rockin’!
That was two years ago, no sign of them since.
I also allow possums to shelter on my property. I do not have horses, just ducks, and the possums have no access to them. Possums, I am told, eat thousands of ticks, and are mostly unaffected - do not carry - Lyme Disease. This year I have seen maybe four ticks. On any of us, not even attached (just luck about that). Maybe it’s having a better balanced natural environment that helps, I cannot prove it.
I hope this is some encouragement. One person’s efforts may not seem like much. At the same time, I choose not to just sit back and do nothing. And I have friends and associates around the world, dozens of them, who are leading groups of people in restoring ecosystems.
I often recall this quote from Tolkien’s Lord of the Rings, Aragorn: I see in your eyes the same fear that would take the heart of me. A day may come when the courage of men fails, when we forsake our friends and break all bonds of fellowship, but it is not this day.
Organic roof tops in cities is a great idea, we need to stop the other pollution, too, for that to work successfully. Less fast food and more fresh markets would be nice. But then some humans don't want to cook, just eat, often too much.
