Iain Woodhouse, of Edinburgh University, likes trees. He specializes in mapping forests using satellites, so he knows a thing or two about global deforestation. And to get it into people’s thick heads what the world would be like without trees, he photoshopped all of the trees out of a few famous paintings, the BBC reports.

Here’s “Sunday Afternoon on the Island of La Grande Jatte,” by Georges Seurat, in the original:

And here’s Woodhouse’s version:

Here’s Vincent van Gogh’s “Olive Trees with Yellow Sky and Sun”:

And here is the new version:

It’s pretty depressing.
