Future dystopian concept

Centuries ago a legion of alien creatures landed upon the planet earth. These aliens, having lost their home planet by means of their own arrogance, sought refuge on other planets with a similar atmosphere with intentions to blend in and survive without disturbing local wildlife. For decades these aliens observed and lived peacefully on the Earth, releasing spores to reproduce only when necessary and using their parasitic abilities to increase the intelligence or physical abilities of creatures slowly when needed for the earth to develop. These aliens, that we foolishly coined as fungal plants, even helped with the growth of the human race due to their particular fascination with the creature. The alien peoples, humans, and creatures of all the earth lived in relative harmony for hundreds of years until the humans began to create their own developments beyond what the fungal aliens could provide for their hosts. The aliens, out of proud curiosity, allowed these developments to occur. However, before it could be stopped the humans innovated beyond what was thought possible. Every decade something new, every decade creating more and more, and using more and more. Every decade the human race took one more ignorant step towards destroying the planet. As this continued the fungal aliens began to become more and more cautious and worried about the state of their adopted home. In a blind panic to save the earth they tried to infect the minds of human scientists, knowing that they can only develop their beloved human creation in a slow manner. It was all in hopes that if they can momentarily increase the intelligence of the science community within the human race they could perhaps genetically splice multiple species and save as many creatures as possible from the impending, carcinogenic doom of the earth as technology takes over. The results of these botched experiments resulted in dire and ugly consequences.
