This is our natural tendency, to seek the quick rewards but we are intelligent beings, capable of planning.
The same arguments can be made for future of your own children, retirement plans, planting trees, long term investments, etc. Yet these are not as controversial and we accept them, more or less, as generally good practices.
This natural instinct on its own is not enough to make people forget the coming danger. You need constant advertisement, news cycles, opinion pieces, disinformation campaigns, etc. to make it stick.
