Why this concerns all of us

The new UN treaty for high seas conservation impacts everyone, as our oceans are crucial for climate regulation and food security. With fish stocks dwindling and marine biodiversity at risk, this treaty is a step toward sustainable fishing practices that can protect our seafood supply. A healthier ocean means healthier communities, ensuring we can rely on marine resources for generations.

Nature's hidden secret

The high seas, covering nearly half the Earth's surface, are home to species that remain largely undiscovered. For example, hydrothermal vents, often referred to as 'black smokers,' support unique ecosystems that thrive in extreme conditions, showcasing life forms that could hold secrets to biotechnology and medicine.

The person whose life climate changed

Maria Lopez, a fisherman from a coastal village in Chile, has seen the effects of overfishing firsthand. For years, her family relied on abundant fish stocks, but declining catches have led to economic hardship. The new treaty brings her hope. Maria dreams of a sustainable future where her children can inherit a thriving ocean. She actively advocates for marine protected areas, believing they could restore fish populations. With the treaty in place, she feels empowered, knowing that collective international action might ensure her community's way of life can endure.
