Nature Needs Half Steering Committee

The leaders of the Nature Needs Half movement are evolving and growing international enthusiasm to protect 50% of wild nature by 2050. Although representing diverse backgrounds, expertise, and skill sets, they share a common belief in building a healthy and respectful connection between society and nature. Since 2017, they have helped Nature Needs Half partners and affiliates work together to expand the scope of their conservation projects, knitting together the coordination necessary to effectively and sustainably defend our wild home.
