This year, Jack's embarking on my fifth fundraising challenge, Climbing 100 Mountains in 50 days, to raise funds for Operation Ocelot with World Land Trust (WLT) Patron Steve Backshall, a campaign that will help to protect some of the last 7% of Brazil's Atlantic Forest to help make it possible for WLT partner REGUA to protect acres of tropical habitat for ocelots, tapirs, sloths and hundreds of other species.
