Idolized sex is not a global problem, over population is. Who cares thats its a problem in one country.
All that factors into the larger issue is a global problem. You want to fix the world, start with cleaning your room.
Again if we cant even take care of what we have now why argue or cry about the unborn?
Because killing children is always evil. Your killing children to prevent over populating planet... so that life can be better for you and your friends.
Want to save the planet? Promote safe sex and / or waiting until married. (Condoms are cheap). Encourage strong family units so that children grow up with morals and education to make better choices. Fix your home / country first then you can graduate to helping the rest of the world.
