Oh no. Please don't tell me that you're trying to propose aborting babies. Why don't we just kill off those people who buy plastic bags and throw them on the sidewalk? Just kidding!
Seriously, I think this is a great idea. Instead of having kids, consider adopting one. That way we minimize carbon emissions, we fill that space in our lives (if you are one who loves kids), and we get to help out a child have a good chance at life.
