if all organisms stop the process of reproduction then there will be no more generations after this organisms and thus these organisms will be the last generation of this world and after the death of these organisms there will be no life left on this planet and thus the Earth will be destroyed because no daily life processes which were carried out earlier are not there because of no human activity and because there will be no human left . The plants will also die because they will not get carbon dioxide and thus photosynthesis will not take place and as plants will not get food so they also die....
