Mark on the Wind
Mark on the wind and footprint on the clouds. It's as impossible as it sounds. But over years, we 'humans' have done the damage with our careless attitude in using natural resources and then polluting the same by not taking good care of it.
Earth is made up of these 5 elements. The earth, sky, water, air and fire. We have polluted every element and now the earth revolts back. We need to understand that if these elements dont exist in their natural pure form neither would we humans.
