When miners stepped foot on the island, they introduced invasive species that destroyed the habitat. The tiny island of Redonda, about a mile long, was formerly a haven for several species of seabirds. AdvertisementAdvertisementHumans deserted the island around the 1930s, but the mining operations left behind invasive species, mainly domestic goats and stowaway black rats, that wreaked havoc on the island's ecosystem. In 2016, environmental groups such as EAG launched restoration efforts to bring back the local plant life and animal species native to the island. We just removed the rats and the goats, and the island transformed right in front of our eyes," Bradshaw told CNN.
