Vikings:For Centuries the Native Indians have claimed to be able to make it rain,but as well they have been located to reserves where they live with nature and live off the land so there is a great better understanding of knowing what your losing,as in respect to global warming and being able to appreciate the planet as they say you are what you eat,therefor if you use something you better be able to replace it,as in if you cut a tree down plant another,but if you cut too many trees to build too many homes, where will you plant the next one,i guess space aviation is more important than our planet.
