I don’t think that’s a fair reading of the article, the three points it mentions are:
-
Invest in trees and green spaces. This ones achievable at a small scale.
-
Prevent new construction in risky places. This ones literally free because it’s just not doing stuff that’s harmful.
-
Employ nature-based and multipurpose facilities. I’ll admit this one could end up being pricey.
Then it has a whole bit about how these policies could save money.
Either way, I’m not reading this as suggesting expensive rebuilds.
What’s your reasoning for thinking its not gardening?The article goes into some detail to explain that a fair amount of gardening skill is involved and its a lot more than just letting your lawn grow wild.
