We must protect 30% of the Earth's land and seas to prevent environmental disaster, says conservationist
Keeping areas of land and sea safe can help tackle climate change, says Enric Sala
After years as an academic studying the human effects such on ocean life, Enric Sala had a daunting realization.
"I was studying ... the impacts of fishing and global warming, and it was bad news," he said. "I felt that all I was doing was writing the obituary of ocean life."
"I felt like the doctor who's telling you how you're going to die with excruciating detail, but not offering a cure."
This epiphany motivated Sala to quit academia and become a full-time conservationist. He joined National Geographic in 2008 as an explorer-in-residence.
His new book The Nature of Nature: Why We Need the World makes the case for why the human species needs to preserve nature to ensure our future.
Since 2008 Sala has led the Pristine Seas project, which aims to inspire world leaders to commit to conserving 30 per cent of the world's oceans and lands from human interference.
"It's not the only solution, but it works pretty quickly," Sala, who cites the late oceanographer Jacques Cousteau as one of his childhood heroes, told The Current's Matt Galloway.
"If you protect an area of the ocean — set aside an area without fishing, without damaging activities — marine life has this extraordinary ability to bounce back."
Sala hopes to achieve this goal by inspiring powerful people with the majesty of the Earth's ecosystems.
In his book, he recalls an ocean expedition in the African nation of Gabon, where he was joined by President Ali Bongo Ondimba on the final day. Sensing the president was growing bored, Sala asked him if he would like to pilot their underwater robot.
"He started driving the robot, and we see this dark shape in the distance.... There was this big rock at the edge of a seamount full of fish, full of starfish, and all of a sudden five huge groupers show up. That was the epiphany," Sala recalled.
"He said, 'Wow, I didn't know we had these in our country.'"
Gabon now has 20 marine parks, covering 28 per cent of their exclusive economic zone.
Conservation vs. economics
While the 30-per-cent goal appears ambitious, Sala argues it's not unrealistic.
"We are not talking about a luxury for rich countries or a romantic ideal, we're talking about our life support system," he said.
Galloway challenged Sala by acknowledging that conservation requires longer attention, whereas industries reliant on natural resources, such as fishing, provide short-term economic benefits.
But Sala believes that questions of conservation and economic benefit go hand in hand.
"Economic development [versus] nature is the wrong question," he claims. "If we tamper with nature on one side of the planet, everybody could suffer."
"Let's invest in preserving our life support system. That's the best thing we can do for the future of humanity."
Ecology and pandemics
Sala claims that the COVID-19 pandemic has been proof of why global investment in future conservation is required going forward.
"This pandemic has shown that not investing in the long-term has global consequences," Sala says.
What it will cost to protect a third of the planet is less than what the world spends today on video games.- Enric Sala
In fact, Sala argues that the global economic response to the pandemic has cost much more than it would cost to conserve 30 per cent of our environment.
"What it will cost to protect a third of the planet is less than what the world spends today on video games."
