But here is some good news: restoration is exactly what some people are doing, such as the people in and out of Mozambique who are restoring the Gorongosa National Park.
Our Vision from Gorongosa National Park on Vimeo.
People have lived in the Gorongosa area for 300,000 years -- 10,000 human generations. A little over a century ago, the need to protect it from overuse was recognized, and for most of the 20th Century its natural communities did benefit from preservation efforts.
In recent decades, however, war in Mozambique harmed and endangered both the natural communities of Gorongosa and the human communities closely connected to it. The Gorongosa timeline outlines the place's story from pre-history through colonization to protection and conflict.
Most recently, a positive story has emerged, as local and global people are working together to restore the park's ecosystems by healing its connections to surrounding human communities. The results include an ecotourism initiative that is much deeper than most, which is explored in The Guide, which is the story of the relationship between Gorongosa neighbor Tonga Torcida and the imminent biologist E.O. Wilson.

When I started studying demographics in the 1980s, we were concerned that human population was experiencing exponential growth that was exhibiting a "J-curve" trajectory. That is, the compounding of population growth was leading to increases that seemed destined to accelerate for decades to come. Around the turn of this century, however, negative feedback processes began to slow that growth. A pattern that seemed to have no end in sight now seemed to have an end point -- a likely plateau of human population at around 9 or 10 billion in the middle of this century. This is known as "S-curve" or sigmoidal growth; we are currently in a long period of population that increases at a decreasing rates.
For those concerned -- as we all should be -- about providing resources for the growing population, this is good news. It means that our task, though daunting, is not infinite. If we can find a way to support ourselves sustainably until 2050, we should be able to do so after that date. In The Bottleneck, Wilson makes a corollary claim -- any species and wild lands that we can protect until 2050 have a reasonable chance of being protected for the long term.
I look forward to watching the full version of The Guide documentary, and perhaps with luck, to visit this park some day. Because the history of colonization connects Mozambique to Brazil, I do speak the local language.
