The day finally came for all mankind that would choke his very existence from the planet he promised to love and honor. No one could leave their homes because the smog was getting thicker and thicker by the minute. The sun that used to shine so bright that every man, woman and child took for granted was nothing more than a dot like a flashlight with weak batteries that you hit with your hand several times in hopes light will shine. You can replace batteries in a flashlight, but when the sun doesn't have a chance to shine on everything that depend on its heat source things start to die including the human race.
Scientists from all over the world tried their best to find a solution, but it was too late, and all they could do is sit back and watch the whole human race die out.
