Indeed. Madagascar is a slow-motion environmental catastrophe because every family has many children and each of those children eventually needs to slash-and-burn rainforest in order to plant enough rice to sustain themselves. Also a lot of tree-felling to make charcoal, because for whatever reason Malagasy villagers cannot afford e.g. kerosene to cook with. The result is the steady eradication of all those cool lemurs and other rainforest wildlife, but the perpetrators of this destruction are not millionaire industrial fatcats like people often imagine, they are dirt-poor subsistence farmers.

And without significant investment by those with resources, asking them to preserve the environment is a direct ask for them to go hungry or cold for the sake of the environment. This is an ask that 99.99% or more of the human population will absolutely ignore.

I guess a solution would be give them supplies so they aren't forced to destroy their own backyard in order to survive.

Or how about we invade Madagascar, ship all these poor folk to NYC, and declare the entire region a wildlife reserve?

Not cool. This kind of imperialist mindset has historically been at the head of some of the most awful actions in human history. Including forced relocations, imposed poverty, sustained resource theft, sustained vandalism and theft of local artifacts, slave labor, and even genocide.

If the rich world really cared about the wildlife in Madagascar we would fund green local infrastructure projects so that the local population could enjoy a sustainable lifestyle on their own.
