Many posts here about how sad and disgusted people are. Not much about people taking personal responsibility.<p>What do people think the carrying capacity of the planet means? Sustaining more humans means sacrificing other life that competes for our resources. It means pollution rising until it doesn't quite kill us but is well above the levels of a pristine, clean environment.<p>Nobody wants to live near the carrying capacity because approaching it means sacrificing anything that doesn't keep us alive.<p>Every round trip flight across the country you take contributes almost one year's allotment from the Paris agreement for one person -- <a href="https://co2.myclimate.org/en/portfolios?calculation_id=719701" rel="nofollow">https://co2.myclimate.org/en/portfolios?calculation_id=71970...</a>. Flying first class and you're well over it. Eating meat contributes a lot too. Having more kids in western cultures contributes significantly.<p>Who among us, reading this, hasn't gone over their annual limit in just a few hours of flying, not to mention their regular life otherwise? How many have blown past their Paris limits already this year?<p>Some would say the damage was done by past generations. Okay, well what beautiful part of nature will our behavior destroy years from now? People keep posting to HN that since we can't change that a lot will happen, it doesn't matter any more, we should just enjoy ourselves, but there are different degrees of destruction.<p>Alternatively, we can fly less, drive less, eat much less meat, and have fewer kids. We don't need to wait for legislation. In fact, it's the fastest way to get legislation, since politicians follow voters.<p>In my experience, acting on all those things improved my life tremendously (including not flying for a year+ <a href="http://www.inc.com/joshua-spodek/365-days-without-flying.html" rel="nofollow">http://www.inc.com/joshua-spodek/365-days-without-flying.htm...</a>), more than almost anything else. I'm more fit, enjoy my neighborhood and neighbors, and spend less money and there's nothing special about me.
