Planet Forward @ PBS.com, Has a great deal of information on enviromental issues for our future,so please take a look,One example is as of 2008 we used one trillion  dollars of imported oil,coal has stripped plenty of our mountain regions,as for coal we will run out of that resource in the near future also,but on the other hand if every Canadian, American and Asian,business switched over to wind or solar power,our planet's  side effects,(global warming,green house gases) would create a much cleaner level of h20,and help to save our planet from getting any hotter in the near future!!!
