The world does appear to be changing.
For years, the scientists have been warning of global warming. The majority of people, in western countries at least, have accepted that our actions were causing a real problem, but few governments were willing to do much about it.
But the problems are becoming more obvious, the alternative technologies are become cheaper, and more and more governments are making realistic decisions to change to renewable energy. WE can hope for real change.
But there’s still much to be done, and we can all play a part.
