Great idea! Competition among tree-lovers to grow and care for trees.
I am also looking to join the comp. I don't have a slogan to sing out. But I have a concept of " Tree of Life": where everyone has a (companion/life) tree to grow with. We can look at trees and how their life human are doing. Any tree grows well when it is cared for well or the man/woman of life is doing well and vice versa.
[I have some 10.000 trees (of life) at my place. more than 5,000 of them can produce enough oxygen for 2 people per tree. (Go on - do a search to see how many trees would produce enough oxygen for a small car to run 100 km. ;-)
I don't have enough evidence but I think "predators" like owls, hawks, snakes,... come by themselves once there are enough "preys" like rats, lizards, young birds, large insects,... which feed on smaller preys or vegetation or pollinating ... pollinators need nectar/food (flowers) all year round ... so leave those weeds (with tiny flowers) alone please ;-)
