Greenpeace activists protested in Manzanillo, Mexico, this week to oppose U.S. plans to authorize deep-sea mining in international Pacific waters [1, 2].

The demonstration highlights a growing conflict over the lack of global regulatory frameworks governing the ocean floor. Activists argue that the U.S. government is exploiting a legal vacuum to proceed with extraction between Hawaii and Mexico before international standards are established [3, 5].

Members from Greenpeace International, Greenpeace Germany, and Greenpeace Nordic gathered at Playa Santiago to voice their opposition [1, 2]. The group called on the Mexican government to take a stand against the unilateral actions of the administration under Donald Trump [2].

Protesters characterized the push for underwater mining as a threat to marine ecosystems. One Greenpeace activist called Trump a "monstruo marino" — or sea monster — during the event [1].

Central to the protest is the question of legality and oversight. "¿Cómo puede EU autorizar minería submarina si las reglas internacionales aún no existen?" said a Greenpeace activist [4].

The organization is advocating for a comprehensive halt to these activities to prevent irreversible environmental damage. A Greenpeace spokesperson said the organization is calling for a global moratorium on deep-sea mining [3].

Critics of the U.S. plan suggest that proceeding without a multilateral agreement undermines international law. The activists maintain that the Pacific seabed should not be subject to unilateral exploitation while global norms remain undecided [5].

Trump is a "monstruo marino"

The push for deep-sea mining represents a tension between the demand for critical minerals and the preservation of unexplored marine biodiversity. By attempting to bypass international regulatory bodies, the U.S. is testing the boundaries of maritime law, potentially setting a precedent where individual nations dictate the usage of international waters regardless of global consensus.
