Nature Needs Half

Why Now?

How do we achieve the goal?

Nature Needs Half  is a science-based and common-sense vision of a relationship between people and nature that ensures enough natural areas of land and water are protected and interconnected – and of sufficient size and resiliency – to provide life-supporting ecosystem and biodiversity services that are essential  to both  human health and prosperity and  a bountiful, beautiful legacy of wild nature.


The magnitude of the global ecological crisis we face today – and the availability of better and more accurate ecological information — demands that conservationists provide a clear and accurate global conservation target that will realistically keep our planet viable.


Reaching the goal of at least half is ambitious but achievable. The short term milestone for the progress of this vision is to move urgently to protect at least half of the planet’s remaining large, mostly intact wilderness areas (for example Boreal Forests, the Amazon Basin, and formally protecting Antarctica), while achieving incremental gains by quickly protecting surviving remnants in fragmented areas of very high biological importance.

423 #cities around the world are inside 36 #biodiversity hotspots... There areas are home to a high #diversity of animal and plant species. We must live harmoniously with nature and wildlife, if we want to safeguard these habitats and #species!

Wonderful news! 👏🏼 "1.8m sq km reserve –5x the size of Germany – would ban all fishing in a vast area of the Weddell Sea and around the #AntarcticPeninsula, safeguarding species including #penguins, killer #whales, leopard #seals and blue #whales."

This planet is beautiful 💚🌎 #ProtectIt #NatureNeedsHalf

We hope everyone has a wonderful #ValentinesDay! 🐵❤️ Picture by @Swidstrand, #WildWondersofChina
