What an amazing question to be asking these times! I have already seen what happend when everybody was in lockdown.
It was such a beautiful sight :D
Life is not back to normal nor do I wish it to be. I feel for the business owners but its just noise at this point and the world was so much better off without us stressing around feeling "useful".
So. What could change?
Well, a bit of context is needed I think. I am currently living in Copenhagen, Denmark and I don't think we are as bad as many other countries. On "big" public roads we still some places have trees planted in the middle which is amazing and we also host quite a lot of parks and we are quite good when it comes to renewable energy with our windmills at the sea.
But, we ain't perfect.
Some things I would love to see is "parks" on top of roofs. Not only does this protect the roof tiles so they last longer it also helps reduce the CO2 or catch the emission.
I also want to see either more solar panels on rooftops or glass made of out of solar panel material (How ever that works xD) which is easily changable if something happens to it, like multipurpose glass for big buildings.
Get a plant garden! You can grow random crops or just plant the ones which can absorbe the most CO2 :D
Ever heard of Solar paint? Well, its what it say it is. You can read more about it in the article down below
