CLEAN : Conservationists turn poisoners

The video discusses the challenges faced by giant tortoises in the Galapagos due to invasive rats, which were introduced by humans. Conservationists have been breeding tortoises in incubators on Santa Cruz Island because rats on Pinzon Island destroy tortoise eggs. Efforts to eradicate invasive species, including rats, goats, rabbits, cats, and donkeys, aim to restore the Galapagos ecosystem to its original state. The video highlights the success of these efforts in preserving native species and the hope that giant tortoises will soon breed naturally on Pinzon Island.
