STOP DEEP SEA MINING
For over a decade, the Deep Sea Mining Campaign has been a relentless force in the fight to protect our oceans from the devastating impacts of deep sea mining.
Small but mighty, the Deep Sea Mining Campaign (DSMC) was founded in 2011 and has led the charge against this destructive industry. Using our agility and expertise we challenge powerful interests and amplify the voices of those who say “No” to deep sea mining.
Our campaign has been at the forefront, exposing the dangers, rallying global support, and driving meaningful change. We believe that the deep ocean—our planet’s last untouched frontier—must be preserved, not plundered.
Join us in protecting the depths and ensuring a future where the ocean thrives, untouched by greed.
Together, we can stop deep sea mining in its tracks.
