Updating our Views on Nature and How to Save it

What is nature? What does it mean to preserve, or save it? Science writer Emma Marris says one common definition of nature in North America is the way any given place was before European explorers arrived and began changing the landscape. Therefore, saving nature would mean returning the land to how it was before their arrival. But, she says that idea is flawed because there are countless examples of land management by indigenous people: relocating useful plants to new environments, creating systems to manage rainwater, and clearing land for crops. And, human impact on the environment goes back much more than a few hundred years. Marris notes that pretty much anywhere you look, there is evidence of major changes with the arrival of humans – in particular, the extinction of large land mammals like the woolly mammoth.

Today however, the planet is largely tailored entirely to human existence. Nearly 40% of the ice-free surface of the earth is agriculture. Domesticated livestock far outweighs wild animal life. Species have been moved around, in some cases wreaking havoc on ecosystem. And of course, there are growing impacts of climate change – even hitting places on the planet where humans have never lived.

Marris argues that in order to effectively conserve nature, we have to change our perception of what nature means. She says her old way of thinking, that nature was a pristine untouched and unchanged place didn’t match reality, because if left alone, all places will change. So, she came up with new definitions, including the idea of resource-intensive land management to keep certain culturally important lands as unchanged as possible, and also the idea of novel ecosystems where uncontrolled landscapes have transformed themselves.

With this updated understanding of what nature is, Marris proposes an updated take on conservation. She suggests dividing land into three different styles of management: restoration, innovation, and observation. In her exciting and hopeful talk at UC San Diego, Marris goes on to give concrete examples of how these strategies have worked, and might continue to work around the world.
