This is because on people's mind "Life is too short to enjoy it in the way you want",so they are doing those things for their pleasure and making mistakes is human nature.
And our wrong choice might make it more shorter than intended.
For example we are now finding out that micro plastics are a very big problem in the world, so now there is time to find the solutions. A lot of knowledge is missing, but I think some knowledge will come to help deal with this big problem. Humanity is always finding solutions, even to problems we make.
Finding the solution and society following the solution on their own will are 2 different things.

Ahh! Interesting argument but choices that have bad impact are just choices not the wise decisions.
For example : somebody is dying and you should act fast and the only way you could have save that person is to rush him/her in the hospital then basically you are over speeding are you actually making a bad choice?
Really subjective but by overspeeding if you met with accident.
In my opinion, people lack discipline and responsibility.

Tl;dr
I think our choices are governed by our own convenience and I agree that in some case we lack disciplines and really do not understand the consequences.
