There is no possible way mankind or anything we invent or use on this planet, have any effect large enough to adversely affect the entire planet! To even suggest such a thing is giving humans a bit too much ‘credit’, or in other words, we think we are that important, that we COULD even have an impact on the planet. LOL
However if hard data supported this, and it was accurate, it appears, we as a race of people do not care that much about our future or our kids futures, as we continue to pump out more and more cars and trucks every single day, not even slowing down, in fact they try to put as many vehicles on the road as possible, ANY other product proven to be so destructive, would be banned immediately and all of the remaining ones destroyed, anything less proves mankind does not care about the future of the planet.
Im sorry, but if such products are so harmful to our planet, then why, in the year 2013, has NO ONE came up with something better? LOL we claim our world today is so smart and high tech, yet we all mostly still drive vehicles with internal combustion engines, something that has been around for over 100 yrs, and in this amount of time, NOT ONE COMPANY or person has ever thought of something better to takes its place??? If this is true, then we have serious problems as a species.
