Explain how conservation has saved the bald eagle.

Pollution and pesticides had made bald eagle in the list of endangered species for several decades. The DDT spread across the aquatic ecosystem by agricultural washing and the Bald eagle began eating the contaminated fishes. There have been immense efforts done to recover the population of the bald eagle. The recovery process included removal of the alien species and helping the native species to recover in its habitat. The Bald Eagle Protection Act prohibits the killing and possessing the bird or its egg, feather and nest. The efforts to restore the species included elimination of the use of DDT, the habitat including the nests were protected from all kinds of human intervention. The recovery had the main conservation objective to maintain the current population and providing the required conditions to increase the numbers. The species is under vigilance of all sorts and the numbers have increased every year since then.
