Deforestation is a common cause of desertification worldwide. Trees help to capture moisture from the air and bring it to ground. Cut them down, and the moist air blows past. Trees are commonly cleared for farmland, and then the farmland has to be abandoned when it gets too dry.

In the Amazon basin and along the northwest coast of North America, trees were the basis of productive agriculture, carefully chosen mixes of trees of different sizes and species. To this day the Amazon basin is dominated by tree species that were once cultivated throughout, supporting tens of millions until they were wiped out by smallpox and other pandemics. In North America, such tree gardens can still be found centuries after they were abandoned.

There is evidence of lush farms in what is now the Sahara desert and civilizations that existed there had significantly more resources.

Early Egyptians documented this as well. ...and the Carthaginians were likely the last holders of that fertile land before civilization moved north in the Roman Empire.

Global temperatures rose causing desertification along that entire latitude.

Language is great.

I remember two meters of snow, digging tunnels through it and such.

And I remember four distinct seasons. Now it's more like a long summer, a long autumn, and short spring and winter.

They wanted to cut the trees along the roads in France too for similar. They wanted to remove the trees up to a certain distance which I can't remember.

The issue is that whole forests are being removed. If they weren't, removing a bunch of trees along the roads for safety wouldn't make that big of a difference.

But trees in cities is a different beast, though, and I think it's criminal to remove those, especially in Romania where, thanks communism, there aren't that many trees to begin with.
