I am somewhat concerned... I don't see why active steps aren't being taken. Alternate power sources... why isn't solar power being used as much... I mean everyone still used regular electric power from pollution creating power plants. We need to make a switch over to a non-pollutant gasoline for transportation as well, such as hydrogen. If we take two active steps such as promoting a nonpolutant transportation gasoline and nonpolutant household electricity source the earth would be a much cleaner place.
