I think this is moving in circles. I have no clue (without offense) what you people want to say? That its difficult to find solutions or alternatives? Hell yes! But again. What is the alternative to not trying it? Not thinking about it? Not at least use what is possible at the moment with curent technology? The real issue is that many argue they do not feel responsible cause others are not trying anything or that economy would see to much preasure the last conferece was seen by many people as a dissaster and dissapointing cause they did what they always do "talking", talking about how important it is to do something. Fact is that we have to start somewhere. That we reached a point where discussions, on a political level arent advisable anymore. Most of the things that start to affect humanity are not serious but they will be very soon serious enough what ever if its global warming or just a change in weather. We have to realise that we actualy do NOT have any other choice. If for example Mars or Jupiter would be planets just like our earth nice, warm and viable. Then maybe, yes then we eventualy would have no reason to do everything that is possible. I just think that there is a lot possible if certain groups, nations and companies would just "try" it. As said, it would be already a start to prevent places like those in Africa, Asia and Eastern Europe. If we would stop to send our waste in poor nations where they do not care or have not the resources to care about the waste. We still have a lot of tolerance in our own industry when it comes to technology and improvements. And cars should be really our smallest problem as they are maybe just responsible for 5% CO2 production. Already the methane of cows all over the world for food production is a lot worse. We should start eventualy to invest less in meat. To manufacture 2,2 pound meat one has to waste more then 15 pound of wheat and that only counts for the food as it doesnt even mention the needed energy for transportation and preparation. This will probably become even worse in the future considering the fact that China, Russia and India manufacture more and more meat since those states reach more and more economical wealth.
