No water!
A big problem on planet earth is the water because only about 3% is freshwater but 2% is not accessible to us because it’s in the ground or frozen in glaciers this a big problem because that means less then 1% is accessible to us.But there is one other factor in the water problem and that is us the human race we are constantly using more and more water so if you try to imagine the future about a hundred years you think something along the lines of star trek or star wars but because we have so little water the human race might fall before that happens.
