Indeed, humans are not the only animal that kills for sport.

Dolphins absolutley obliterate porpises just cause they can, using echolocation to target vital organs, ramming into them, flinging them out of the water with enough force to break their spine.

A conservative estimate is that feral cats kill 1.3 billion birds per year, and have caused more then 20 species of bird to go extinct, and a 2008 survey of predation by domestic cats administered to a randomly selected population of 458 cat owners in metropolitan perth showed that they killed even after they just had been fed.

Also one thing I noticed is that you said OP, we destroy the trees with out replacing them, just saying that between 2004 and 2012, deforestation in the Amazon Rainforest plumeted by 84%.
