Leonardo DiCaprio Instagram – How many people will it take to protect 30% of the planet’s wild lands by 2030? Five times more protected area personnel than we have right now. A new study from @Rewild and partners estimates that we need a workforce of 2.9 million people, including 1.53 million more rangers. This is the first global census of protected area personnel since 1999 and the first-ever census to include rangers.
