What went right this week: social media’s ‘big tobacco’ moment, plus more

In the race to conserve our oceans, Chile has emerged as a frontrunner after its president signed a decree to create one of the world’s largest marine reserves. 

Following a campaign led by ecologists and coastal communities, President Gabriel Boric signed off plans to protect 337,000 sq km of ocean around the Juan Fernández archipelago. The region teems with species, including whales, seabirds and the Juan Fernández fur seal (pictured), once thought to be extinct.

Once implemented, the protected area will link up two other marine reserves, covering a combined total of 899,268 sq km, which is roughly the size of Nigeria. 

“For generations, our community has lived in harmony with the sea, relying on it for food, livelihoods, and identity,” said Julio Chamorro Solís, president of the Organización Comunitaria Funcional Mar de Juan Fernández. “By expanding our marine protections, we ensure that future generations will inherit healthy oceans, thriving fisheries, and the cultural traditions that bind us to our home.” 

The designation means that Chile will soon have more than 50% of its waters under protection, far exceeding the 30% by 2030 target agreed by 190 nations in 2022.
