Honestly i think about that kiind of thing all the time.Even when i was a kid things were so much different.We could actually swim in the rivers and creeks around here and they were cool we all did it.There is no way that kids can do that now as they are more like a breeding ground for diseases or full of pollution its not good.Really there are not many pristine places left in the world but there still are some that have not really been effected by pollution or the environment and these are the places we need to keep like that.Luckily some beautiful parts of australia especially the rainforests and animals are protected.We are not even allowed to light fires here in the backyard anymore,we have water restrictions so people dont waste water.Every house in aus has large recycling bin we are the most environmentally consious country in the world apparently.
