The true right thing is to let some animals kill and eat you, or just huck yourself into the ocean.
The population of the mis-informed vegans / animal rights activists sometimes gets behind "If there were no more humans, life on planet earth would be better"
That may be true in terms of increasing the Total Bio-Mass, on the surface and in the ocean.
However, Erasing humans would be a big mistake, because we are the most intelligent species.
Your body has many components, some of them can be lost while the others can still function..
Killing off humans, would be like removing the executive functions to the brain.. Yes, we can do that, (lobotomy), and the person would still be - alive - , however, this person wouldn't have much of a FUTURE.
If we removed Humans from this planet, another equivalently intelligent species MAY NOT ARISE in time, before the next Armageddon event.
Let's say humans are gone, and we're back to all the elephants, and the whales and the buffaloes on the planes..
What are ANY of those animals going to do , when a big rock hits the planet.. they'll just sit there and die..
There is nearly no hope of those animals protracting life beyond planet earth..
But human beings, we very rarely produce GOOD HUMANS, who goes in the right direction for LIFE, and attempts to rightly challenge the vacuum of cold space..
The space gap is one that we eventually have to cross, because THIS PLANET will be extinguished, it's only a matter of time..
