Wrong.
The fastest growing populations are in the least 'globalised' parts of the world.
Man is the only life-form that is actively involved in deliberate nature conservation. And it is the wealthier, more capitalist of man's societies that does the most. All other lifeforms just devour as much as they can.
Cat, pigeons, etc.
Back to the topic. It's difficult. The best is to keep a crew together for as long as possible, then have a significant break before being rostered with someone else. Not many places can do that easily. (Although with present rostering in most airlines right now that is probably no problem at all!)
