Are you really comparing cutting down a tree to murdering a human being?

yes, a tree is highly beneficial to the environment, it takes a long time to replace it (10+ years for that size, which is important for many other species), a human is not often beneficial on the other side

we could compare human and an insect even, or a human and a whale, it's not really about size

When I was a lifeguard as a kid, I once arrived at the pool to find thousands of flies dead, floating on the surface. I thought to myself, "If these flies were humans, this place would be a battlefield," and went on with skimming the pool.

this shows how lethal are humans with their "swimming pools", that's more my thought, not just directly with that water but all the plastic, energy and resources wasted

I truely love flies, many beautiful species in trees, extremely useful and evolved insect
