Why in news

Scientists revealed that deep-sea mining by The Metals Company reduced animal populations in machine tracks by 37%, prompting calls for cautious exploration by the International Seabed Authority (ISA).

Background

A study by the Natural History Museum, UK National Oceanography Centre, and University of Gothenburg found a 37% reduction in animal numbers near mining tracks. While some species thrived in sediment clouds, experts expressed concern over long-term ecological damage.

Facts for Prelims

  • EnvironmentDeep-sea mining tracks showed a 37% reduction in animal abundance compared to untouched areas.
  • FactSome species were found to thrive specifically within the sediment clouds created by mining machines.
  • BodyThe International Seabed Authority (ISA) is the body responsible for considering a temporary ban on commercial deep-sea mining.
  • PostThe Metals Company is the entity whose deep-sea mining impacts were studied by the research team.

For Mains

Q. Discuss the ecological risks associated with deep-sea mining and evaluate the role of the International Seabed Authority in balancing mineral extraction with marine biodiversity conservation.

Dimensions to cover in your answer

  • Biodiversity loss: Irreversible destruction of benthic habitats and disruption of deep-sea food webs
  • Regulatory oversight: Challenges in monitoring and enforcing environmental standards in international waters
  • Resource trade-off: Balancing the demand for minerals for green energy against marine ecosystem integrity
