Why a billion trees can be planted in Ethiopia but not here

Ethiopia has made the global front page by planting a record number of seedlings for the sake of climate restoration.

Whether and how many of these trees survive to maturity is another issue, but it begs the question why such a tree planting effort can be carried out there in a way that can't, or at least doesn't, happen in more developed regions.

The politics of land use in more developed/wealthy economies is complex. Investors use developed land to make money, so if a bunch of trees are obstructing the view from the road, drivers may not see the business and stop there.

Considering that tree-planting efforts like this one in Ethopia are beneficial for restoring natural climate, what would it take to get people, and business people and investors more specificially, on board with reforesting developed areas so that the climate debate stops being a debate and starts becoming a problem-being-solved?
