Other than the question from JoG2, the only reply worth its "ink".
I didn't want to imply that I am any different, but that doesn't make mine/our actions better. I've had several near-fatal accidents that have cost society quite large sums to rectify. I ride 5000 miles every season for pleasure alone, ignoring that the rubber worn off my tires turn into micro-plastic that has a devastating effect on animal life, which again will end up in our bodies. Etc. etc.
Turning the deaf ear and blind eye towards the problems we as a race cause does not help, though. You may think it is your right to eat until you weight 500 lb and are totally out of shape, but some poor nurses will have to fight with your carcass when you get ill. Which you are quite likely to become. Or if you drive after a couple of beers, you are far more likely to cause an accident than if you were totally sober. And so on. In other words, our selfish actions more often than not have a negative impact on others around us.
So what can be done? Well, the simplest way is probably to make doing the right things beneficial and the wrong things unattractive. Like taxing junk food to the moon and have no taxes on healthy food. Like giving big insurance discounts for putting speed limiters and alcohol-locks in cars, and raising the insurance for those who will not. Like having big taxes on environmentally unfriendly wrapping. Like giving tax reduction for those able to document at least 30 minutes of fairly high intensity physical activity on average per day. Stick and carrot.
