I donโt think anythingโs wrong with trees, but maybe we could also have some of these as well as trees ?
Replace the advertisements on bus stops with a really cool green liquid wall ๐ฎ (but theyโd have to make the glass super thick, these things tend to be vandalized from time to time)

First of all nobody is proposing to replace existing trees with that, that would be silly! AFAIU the people who created this also don't want these to be used where trees could be planted. They are outspokenly designed for already densely packed cities that are already highly polluted and hostile to trees, to start turning things around. Rebecca Watson's 6min take
