It is estimated that, for every million or so humans, seven species of animals go extinct. Do you understand what Means? It means, gone. Forever. The final survivors of a race cast down from life and forever broken into pieces. Never to come back. Ever.
When a species goes extinct, the ecosystem takes a hit. Lets say now that, due to some unknown force, one of those herbivores is now extinct.
The carnivores have less to eat, obviously. And the plants have less eating them. So the carnivores, with less food, have to eat more of herbivore number one, causing their numbers to drop significantly. The decomposers have less to decompose due to the jump in plant life. After a few years of less numbers, the herbivores canDinosaursecosystemIce Ages technology, they would think nothing of you but a god.
Of course, power has its downsides. Two world wars have occurred in just the last century. Nuclear weapons are being stockpiled, waiting to be launched at some unknown county. And most importantly, our pollution made by fossil fuels (Which, ironically, were created by the great beasts that caused the first great extinction) tear into the ozone layer, releasing deadly solar rays into our world.
Going back to our original statement. Species are going extinct at an alarming rate and we continue to grow. Forests are being torn down, removing our ability to create oxygen. And our average temperatures increase, ever so slightly, every year (Dons a proven FACT.)
What if, say, there was some sort of planetary defense system, built somewhere deep inside? As it starts to become inhabitable, the system activates to remove the threat in an attempt to save the world.
The polar ice caps are melting, raising the water level, ever so slightly. What if, one day, the great oceans rise to destroy the threat to the world? To purge the waters and rebuild, millions of years later?
What if that threat was us this time?
