Why 50%


We know the target needed but why is 50% necessary?

50% by 2050

Why 2020?

We can stop the sixth mass extinction if we protect approximately 50% of the 846 ecoregions that provide habitat for all of Earth's biodiversity. That means finding leaders and organizations around the world willing to align exisiting efforts around protecting and interconnecting nature in the region.

What does wild nature do for climate?

It’s simple! Without sufficient amounts of wild nature, we cannot keep temperature rise below 2°C. Why? Because Earth’s primary forests, grasslands, and peat bogs store more than 100 parts per million (ppm) carbon in plants and soils, carbon that must remain in the ground if it is to not contribute to climate change.

In order to avoid the catastrophic effects from climate change Earth must remain well under 450 ppm in the atmosphere. At the end of 2019, the world has just over 408 ppm. Destroying even a quarter of our remaining wild areas would remove a critically necessary carbon sink that is – without any cost to society – helping us avert the worst effects of runaway climate change.

What does wild nature do for extinction?

The data is clear. The single greatest cause of extinction is habitat loss, making the destruction of Earth’s wild places the most severe threat to life. Wildlife serves vitally important functions for all of life. Whales and sharks feed the phytoplankton that emit half of Earth’s oxygen. Rhinos and bats plant the trees and shrubs that stabilize regional climates and produce healthy air. To protect life’s allies we must set aside enough space for them to live. Wild nature is their home.

Over one million species are projected to go extinct in the next fifty years if we do not set aside enough habitat to protect them. Protected areas and sustainably managed and restored lands (areas where human communities dwell in harmony with nature) are the cornerstones of biodiversity and wildlife. They give nature the space it needs to function for the benefit of all life.

What does wild nature do for people?

Besides producing the air we breathe, the water we drink, the soils that grow our food, and the stability we count on, wild nature also provides the livelihoods for over 1.6 billion people! Local communities living in or near wild places count on forests for food and forage, oceans for enough fish to feed their families, and grasslands for places to graze their livestock. Without healthy wild places, hundreds of millions of human livelihoods would be directly impacted, causing global social upheaval and instability on an unprecedented scale.

Why is half needed by 2030?

When is it more effective and efficient to protect something: Before or after it has been destroyed? In the next 20-30 years, we are on track to build 25 million km of roads (enough to encircle the Earth 600x), double the amount of building square footage across the planet, and fill the ocean with more plastic than there are fish. Recovering these important land and seascapes will be much more expensive after they have already been destroyed. We also jeopardize life on Earth by removing essential parts in Earth’s wild, green engine.

The single most efficient and effective step we can take to address climate change, end extinction, and defend human livelihoods, is to protect half the planet by 2030 while it is still functioning for the benefit of all life.

How will we protect enough nature in time?

Indigenous and local peoples have sustained wild nature before there was ever even a “wilderness” or “nature needs half” concept. Nature Needs Half fully supports and empowers local people to continue to manage their lands sustainably, as they do throughout the world. (More than 1/3 of all remaining intact wild areas are stewarded by Indigenous and local people.)

Nature Needs Half envisions a world where nature is protected through a combination of strategies that include: official protected area categories, sustainably managed and restored lands, and sustainable and efficient cities. The good news is that even though only 17% of Earth’s land and 10% of Earth’s seas are protected in 2020, we still have a little over half of Earth’s natural landscapes that are intact. By leaving these undisturbed, we can easily achieve half in the next decade.

What can I do to help?

Your help is needed in 2020 more than ever before! Many people around the world remain unaware of the critical roll nature plays in the well-being of all mankind. Without their support, it is unlikely our leaders will act swiftly.
