Africa is building a wall—a wall of trees across the entire continent and it's changing the world

When someone asks you if global warming is real, a perfect example is a region on the southern border of the Sahara Desert called Sahel. It’s one of the poorest areas in the world. Once a lush green environment, the land has been devastated by climate change, drought, famine, over-farming and other human factors that have caused hunger and poverty for the people living there. There has also been international conflict as to who gets the remaining resources, and masses of people are migrating to Europe because they cannot sustain the living conditions.

But there is hope. That hope is a wall—a wall of trees. It’s called the Great Green Wall. This is about an African-led movement that aims to grow 8,000km (6,000 miles) of natural assets and wonder. Dozens of African countries are working together on the project. Once completed it will span across the entire width of the African continent.

The GreatGreenWall.org reports:

A decade in and roughly 15% underway, the initiative is already bringing life back to Africa’s degraded landscapes at an unprecedented scale, providing food security, jobs and a reason to stay for the millions who live along its path.

The Wall promises to be a compelling solution to the many urgent threats not only facing the African Continent, but the global community as a whole – notably climate change, drought, famine, conflict and migration.

Once complete, the Great Green Wall will be the largest living structure on the planet, 3 times the size of the Great Barrier Reef.

Since the African initiative began in 2007, growth on the land in Sahel has begun to re-emerge. It’s “a symbol of hope that humanity can overcome its greatest threats.”

Over 12 million acres (5 million hectares) of degraded land has been restored in Nigeria; roughly 30 million acres of drought-resistant trees have been planted across Senegal; and a whopping 37 million acres of land has been restored in Ethiopia – just to name a few of the states involved.

The goal is to “achieve a more equitable and sustainable world” by 2030. What an amazing agenda. What an amazing wall. What an amazing way to actually make the world a better place.
