Your fallacy is: Because all things are X and some X are bad, all X are equally bad.
Your game is: Whatever you think of as a humane activity, I can find a reason why it's destroying the planet so you may as well not bother - just continue destroying the planet as you are.
Fact is, everything you do will kill you. Every step you take wears out your body. Every bite of food and breath of oxygen takes you further down the road to death.
What will you do, stay in bed frozen in fear?
There are a billion things to do in life that have less environmental impact than flying around the world to go a jet-ski racing and tyre burning party. Reading a good book [2] :) on a beach would hurt less.
