Even if this was an issue - There is no point in living an oppressed life.
Maybe it's time we start making sacrifices now so the future will be better and we don't leave our kids in an even bigger mess.
Keep in mind, we've already shown that we're OK with messing up the planet for future generations: We haven't taken any serious measures against
- climate change,
- overpopulation (this is 1 "meta" problem which reinforces most others),
- wealth inequality (poverty is now "the new normal"),
- pollution,
- etc.
