Does anyone else remember a while ago when they were saying that an easy thing we could do to help mitigate climate change was paint our roads and roofs white? They said that more of the sun’s energy would be reflected back into space, slowing the rate of warming. Whatever happened with that? Why didn’t we do it?
I think you can still do it. But problem might be reflection.
For roads, while driving it’s easy to understand.
But for roofs it’s about biodiversity. Migratory birds for example.
