Re: The ethics of killing to protecting the environment
Brazil is one of the poorest countries in the world, with less to offer besides naked latinas on beaches and some green and wooden areas called the rain forest.
Gang wars and drug traffic is a part of an average Brazilian these days. With law of jungle in whole Brazil every second Brazilian dies of a bullet. Be It the bullet of a police weapon or that of an gangster.
The only escape from a horrible life as such is football. Where you might have some chances to survive 20-30 years more, settle down some peaceful places like Germany, France, England, Spain, Holland and earn some respectable money to get rich.
Maybe another game that appears to be live saving is illegal mining. I can't blame them for doing so. I might have done the same If I had no hopes and no future.
Therefore no ground of justification can be given to ruthless killings.
Especially not when a civilzed European Country with some respect does that for the protection of whatsoever.
