I honestly don't think that Michael intended anything to do with the hoax is for saving the planet etc. It has been a big issue with many celebrities for a long time and I think it is just that with the great catastrophes in the world, floods.tsunami etc people are more aware now than they were say 5 years ago. he did care about the state of the world but IMO this is all coincidence and has nothing to do with his "death". There is 75% of the world living as what we call "third world" trying to survive every day and dying of disease which a few dollars can cure or prevent and living without electricity or running water so the hope of anyone trying to "save the world" when governments are spending billions on nuclear weapons, wars and space travel etc is rather far fetched to say the least. What do people in 3rd world care about the environment when they are dying in their billions of hunger and disease? Are the people in these remote villages even aware of such things? Michael was well aware of places and conditions in the third world.
