  • A Discarded Plan to Build Underwater Cities Will Give Coral Reefs New Life

    A Discarded Plan to Build Underwater Cities Will Give Coral Reefs New Life

    [ad_1]

    A combination of AI, a wild 1970s plan to build underwater cities, and a designer creating furniture on the seabed around the Bahamas might be the solution to the widespread destruction of coral reefs. It could even save the world from coastal erosion.

    Industrial designer Tom Dixon and technologist Suhair Khan, founder of AI incubator Open-Ended Design, are collaborating on regenerating the ocean floor. “Coral reefs are endangered by climate change, shipping, development, and construction—but they’re vital,” Khan explains. “They cover 1 percent of the ocean floor, but they’re home to more than 25 percent of marine life.”

    Currently, Dixon says, coastal erosion is prevented by dropping concrete structures to strengthen the coastline. These damage marine life and ecosystems—but coral could be a “regenerative replacement.”

    Dixon thought of the idea having come across architect Wolf Hilbertz’s plan to build a city underwater, then float it to the surface. In 1976, Hilbertz invented Mineral Accretion Technology: a charged metal framework that accumulates calcium carbonate in seawater like a kettle accumulates limescale in hard-water areas. The result is a limestone deposit known as Biorock.

    “It also grows back eroded reefs and regenerates coral, and species like oysters and sea grass grow twice as fast,” explains Dixon, who has experimented with the technique by creating limestone furniture off the coast of the Bahamas. The duo now collaborate, using AI to predict the outcome of importing Biorock to different sites at different water temperatures, in different weather conditions, with different amounts of solar power.

    They aim to trial their work off the coast of Northern Australia, according to Khan, and hope to recruit affected local communities to advise and champion their plans.

  • Wild Animals Should Be Paid for the Benefits They Provide Humanity

    Wild Animals Should Be Paid for the Benefits They Provide Humanity

    We need to understand the value of nature if we want to protect it—and that should include paying ecosystems for keeping us alive, argues Ian Redmond, head of conservation for not-for-profit streaming platform Ecoflix and cofounder of Rebalance Earth, a company that aims to build a sustainable, resilient, and equitable economy. He’s trying to change the damaging equation where “if the minerals under the ground are worth more than the trees and the animals above the ground, then traditionally, the trees and the animals have to go.”

    Pricing nature’s benefits would help protect it, he suggests. Wildlife tourism shows that people are prepared to pay up to $1,500 simply to spend an hour in the company of an elephant in Rwanda, he points out—so tourists already know how valuable nature is. But what about local people? Filmmakers should share the profits of their wildlife films with those who protect or depend on the ecosystems they film.

    “The irony is that people who live in the developing world, where many of these documentaries are made, don’t get to see them because their national TV stations can’t afford to buy them,” he explains. “We should make people care about the wildlife in the countries where the wildlife lives.”

    And we should pay animals like elephants for their essential arboreal gardening, he argues. “Apes, elephants, and birds are seed-dispersal agents in tropical forests,” he adds. “They swallow seeds and deposit them in their droppings miles away.”

    This has a hugely beneficial effect locally and globally, because trees do so much more than just store carbon. A study in the Congo Basin found that the amount of wood in a forest where elephants still lived was up to 14 percent greater than one where elephants had died out. That basin sets up weather systems that ultimately produce rain in Britain and Europe.

    “Do you think any proportion of what you pay for your [electricity] goes to protect the elephants and the gorillas in the Congo Basin planting the trees that fill the hydro schemes in Scotland?” he says. “Not a penny. There is no valuation of that ecosystem’s service that every one of us benefits from.”

    Ralph Chami, formerly assistant director of the International Monetary Fund, calculated that the value an elephant provides the world during its life is worth around $1.75 million dollars per animal. “That’s roughly $30,000 a year, or $80 a day if the elephant were being paid for the service it’s providing the world,” he pointed out. “But, of course, no one’s paying that.”

    So, it’s time to pay the bill. “I want every gorilla, every orangutan, and every animal to be valued for what they do for the ecosystem, and for us clever humans to construct a system that allows that to happen,” he says. “At the last count, that was estimated at about $700 billion a year. It’s a lot of money. It’s not going to come out of the government’s coffers, it’s not going to come out of philanthropy, but it could come out of the global economy if we construct it thus.”
