What if we attach a finger-print scanner to all the ATMs and other other machines worldwide where a plastic card is used? The finger-scanner will cost around USD 200 a piece and once the investment is made (of course the initial investment will be in millions) the plastic cards can be eliminated altogether and thus the need to produce plastic and also billions in savings in having to issue such cards. I think we will see such move in the near future…very possible.
And, by the way, all these health problems with these gases and other pollutants are short term I guess. Considering our body and these gases,etc. came from the same source, eventually we will either be eliminated from this planet as we consume more and more, or we will develop some forms of mutation to be immune or strongly adjusted to these gases,etc. So what’s the fuss? Natural selection will be done anyway.
All is well 🙂
