Should there be air tax?

[tricker]

I think that it would be the right moment to introduce international air tax to countries. It could be calculated on the basis of country population and industrial developement, and lowered on the basis of acres under forest in that country. Money wich would be gained on that way should be invested in science projects and production of ecologicaly safe inventions.
It should be conducted by UN. What do you think about this?

I think it is a good idea, countries that mostly pollute the atmosphere should pay for it. But certainly it doesn't make any difference to peoples' health.
