The new homo neoneanderthalic or homo galactic species produced by global warming can live in other planets and galaxies where there is no atmosphere. This species can generate energy by water oxidation and create food by photosynthesis. This species is plant-like and can be called as homo planticus. Water will be in excess in the world of global warming with the melting of the polar ice and rising of sea levels. There would not be any forest or agriculture but a human forest of plant-like homo planticus with photosynthesis. The human beings will live in a planet earth with global warming and continuous use of fossil fuels and high atmospheric carbon dioxide. There will be small clusters of neanderthalic population and nation-states that will become extinct. This will be brave new world of galactic neanderthalic species of cyborgs.
