Zimbabwean entrepreneur Chiyedza Heri runs the Ubuntu Alliance, a company that's helping farmers leverage carbon finance to shift to more sustainable forms of agriculture. She's one of more than a dozen young Africans I met at year-end climate talks in Dubai (COP 28) -- a new breed of entrepreneur that the late Ghanian economist George Ayittey calls "cheetahs" because they're nimble, quick, and hungry. Green Cheetahs pursue activities that are pro-nature as well as pro-growth, and today's guest certainly fits that bill.
