The global growth of hydroelectric dams has had a negative impact on tiger and jaguar’s habitat. According to studies, dam construction, particularly in Asia, has wiped out more than one-fifth of the world’s remaining tigers. The number of dams in their ranges is anticipated to treble, putting jaguars in jeopardy.

Tigers have not fared well in the modern world. The animals have lost nearly 90% of their natural range in the last century, despite their iconic and terrifying reputation. Despite recent population increases, the International Union for Conservation of Nature (IUCN) classifies them as an endangered species with a population of roughly 3,500. The jaguars have a similar story to tell. From the southwest of the United States to Argentina, the range of these slender carnivores has been cut in half.

They calculated forest areas that were flooded to create artificial lake for the dams. It concluded that around 13,000 square kilometers of tiger habitat had been drowned. The population of tigers is considered to have suffered as a result of this.
