Why is connectivity important in the rainforest?

Dr. Tom Lovejoy, considered to be the “godfather of biodiversity,” revels in the importance of a connected rainforest ecosystem in the Amazon and the role that his Camp 41 serves — embedding human aspiration in natural landscapes.

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.


"Let’s stop thinking about #nature as small patches of protected areas in the middle of a human dominated landscape. Let’s start thinking about human aspiration embedded in natural landscapes." - Dr. Tom Lovejoy, Planet Forward

Dr. Tom Lovejoy on the importance of big #forests and #connectivity. Small parcels of scattered forests are not the objective. Let's focus on fewer, larger connected patches of land to create healthy areas for #biodiversity to thrive! @nytimes
