List one example where man has interrupted the cycle with disastrous consequences. Have solutions been implemented? What suggestions would you make to improve the situation?

An example where man has interupted the cycle of the enviroment was the Oil spill of of the coast of Alaska in the Valdeze. The only soulution that they had was to clean up the oil and to let the ecosystem try and repait itself, and now in that region the King salomon that use run up the rivers don't, and the Salomon shark that use to live in the region is now on the Verge of EXTINCTION. I would propse that we take the species of salom shak that are alive and put them into breading programs releasing their young back into the wild. Also to take salomon eggs and put them into those rivers and let them come back and reproduce every year.
