This is what the Earth will be look like if our Moon will be crushed due to the earth gravitational force and the pieces of Moon debris will orbit the earth and make a ring.There will be a time when the Earth will be heated up because of lack of trees,then these heat will melt the snow on the South pole and north pole,then the sea level rises.After all land on the earth will be sank in the ocean and finally make a Water world. This may our earth will look like in future
