Mining and warming waters are threatening Chile's underwater forests

Underwater forests teem with life in the icy waters off Chile's northern coast. Red and green towers of seaweed rise from the ocean floor. They provide food for wildlife and income for the locals, as well as oxygen and carbon for the planet.

Scientists believe that these forests have even greater potential for sustainable food, protein and other materials, despite the fact that they are threatened due to human pollution and warming oceans.

"They form a band along the coastal edge, which is essentially an armour of protection and biodiversity," said Alejandra González, a marine scientist from the University of Chile, who specializes on marine ecosystem conservation.

She explained that seaweed captures CO2 and produces oxygen, creating important carbon storage under the waves. She said that seaweed is the future of our planet.

These forests are being under increasing pressure around the world. A British Natural History Museum report in May stated that kelp forest declines at a rate four times greater than rainforests and twice as fast as coral reefs.

Maria Jose Espinoza is the leader of the local Changa community. She said, "Before this, these areas were rich in seaweeds, seafood and fish. Things that most people live off of in this town, from seaweed collection."

Changas have been harvesting seaweeds from the forest for many generations. However, they are concerned about the shrinking forests.

Espinoza attributed the harm to coastal environments caused by tailings from mining in the nearby copper- and lithium rich Atacama Desert, as well desalination facilities being developed by miner.

Chile is the second largest producer of lithium and the top copper producer in the world. The majority of mining activities are located in the north.

Roberto Carlos Chango and his son, a diver who went out to collect shellfish with him, both agreed on the importance seaweed forests.

Seaweeds are important to all animals because they provide food. He said that without seaweeds there would be no shellfish or fish.

Sergio Gutierrez is a Changa harvester of seaweed who gathers the algae and bundles it for sale. He said that the marine forests are a vital part of the local community.

He said, "They provide the basis for our livelihood and so much more."

Marine biologist Gonzalez believes that more policies are needed to protect underwater forests, given the many benefits they provide for the community and the environment.

Gonzalez stated that "all marine organisms related to (the forests), as well as humans, depend on their survival." These forests keep temperatures stable, they create a breakwater effect and maintain the ecosystem. Reporting by Rodrigo Gutierrez, Paposo. Writing by Alexander Villegas.
