David Attenborough

Something of a wildcard entry in this year’s Blooloop 50, Attenborough is certainly influential. “His views on environment and sustainability are going to impact us all,” said one nominee.

Whether it’s cutting back on single use plastic, using renewable energy or banning performing whales, a number theme parks and attractions are making changes to their operations with conservation in mind. But there’s still a lot that can be done industry wide.

Well known for his natural history documentaries, Attenborough has made some supportive comments with regard to zoos. “One of the functions of zoos is to preserve species that are in danger of extinction,” he told the UK broadcaster ITV in 2016. “It would be nice to think gorillas were safe in the wild, but they aren’t.”
