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.


Nature Needs Half founder, Harvey Locke will be discussing achieving the half goal by 2050 on May 25th, at 7pm! #50by2050 ... See MoreSee Less

The #DesertNationalWildlifeRefuge protects one of the most pristine deserts in the American Southwest and provides critical habitat for more than 1400 species of plants and animals. The United States Air Force plans to withdraw 300,000 acres from the Refuge for use as a bombing range and aerial combat training. We cannot let this happen!

Randy Hayes, of @RAN, was honored by @SFSU as an honorary doctorate. In his speech, he acknowledges that the time for change has come, and that now it’s OUR duty to lean in to it and embrace the “Great Societal U-Turn.”

Because every change, no matter how futile it may seem, helps at some level

🌳 How can we respect and protect #nature if we don't think about its needs? #RightsForNature

Today is #WorldTurtleDay, a day to honor & promote 🐢 conservation around the world. Sadly, global populations are declining due to the illegal wildlife trade, climate change, & habitat destruction.

We make up just 0.01% of all life on #Earth and yet we have found ways to cause this much destruction... It's time to give back to the #planet and it's other living creatures. #NatureNeedsHalf #50by2050
