There's millions of trees here, I'm always chopping them down for the steam tram.
Why do trees not grow in Mull? Did someone chop down the last tree, like on Easter Island?

Back when they were building boats out of wood it all got finally
chopped down. Then deer and sheep made sure it didn't grow back again.

So long as you don't chop down as fast as they grow back you'll be ok.
But it's not hard to remove the forest you have permanently.
