The human ego makes us think that we as individuals are extremely important. It can’t imagine that we are part of an immense totality that all fits together perfectly and that death is part of it. So it thinks we need to strive to differentiate ourselves by attention-getting acts and accumulating treasures and fighting against death as hard as we can. But deep down, anyone who has the slightest powers of observation, or the ability to think, has concluded that the world will go on very nicely without us.
It was going on well before people appeared on it. A case could be made that it would have been better off altogether before people ravaged its resources and did not renew them.
Part of the perfection of the world is the process of birth and death. But the ego can’t face death. It fears it because it cannot comprehend the eternality of the Soul. So it creates a scenario that it must fight against. “I will make a name for myself so others will remember me long after I am gone.” If you examine history books you may observe that most of the people who insisted on changing the world were the tyrants and mass murderers of their age.
The planet was designed to function, without many of its components in tact. None of the dinosaurs exist today but the planet is still here. Volcanoes spewed their ashes and created large die-off of plants and animals. Yet the planet survived. It will be here even if people, in their spiritual blindness, exterminate each other from it.
