Great article bro, global warming is a very big issue in our society, all we should be concerned with for now is sustainability, however i also heard that when the Ozone layer is deplicted it regenerate back, if not we all would have being roasted by the sun. That is why sustainability is key because to much of everything is bad. I guese that last image is planet MARS?
Thanks Great Guchi!
Yes, the last one is an artists's depiction of a human colony on Mars.
Nice it so beautiful, how i knew was that MARS has reddish ground surface, so i suspected it was MARS and based on the fact you were talking about astronomy.
