If people know that a certain "thing or Idea" could better the world, Why don't we do it ?

Question

In reference to vehicles and pollution

Answer 1

Not everyone is concerned or even thinks about making the world better

they only care about what is in front of them at the moment

Few people here in answers even care about animals or the Environment

To be sympathetic to Nature or its Animals,invites insults and derogatory remarks ,like treehugger,liberal hippies, environmental n**i etc.

Maybe too many people are too far removed from Nature to realize its importance ,or they are making money by exploiting it.

to give this type of answer always gets thumbs down

you will see

Answer 2

Money the world wants money and we are stuck in this way of thinking that we need money to exist and the sick thing is we do and we cant unite to do so because of the prejudices we all carry.

Are pointed out too much for us to see past our own noses.

sorry got carried away but (opinion)

Answer 3

We never "know"  that something could better the world. We can be moderately sure in a few instances but most of the time, we are guessing on the basis of limited information. There are always costs connected to every benefit. For example, when I took my course in wildlife conservation, the professor (and department head) was sure that multiflora rose made the best fences for use on farms. Today, we consider it an invasive pest. More recently, kudzu was introduced as a soil conservation measure. It does prevent erosion but it chokes out everything else. [Yeah, I know you wanted vehicles but these examples are just too good to pass up.]

Answer 4

Because its really not that easy. When the world population is about 6.6 billion, and say 5 billion drive cars, how easy do you think it will be to tell 5 billion people to "Buy a new car that runs on water!" and "Stop driving your car its killing the environment!" and also, its not very well proven that the pollution is causing G.W
