What’s causing the jellyfish bloom in UK waters?
The jellyfish bloom in UK waters is linked to rising sea temperatures caused by climate change. Warmer seas extend the reproductive season for jellyfish and allow new species to thrive, leading to larger blooms that can disrupt local ecosystems and fishing activities.
-
How are toxic algal blooms affecting marine life and tourism?
Toxic algal blooms, like those in South Australia, release harmful toxins that kill marine animals and contaminate seafood. These blooms also deter tourists from beaches, hurting local economies and highlighting the urgent need for environmental management and pollution control.

What’s the impact of invasive seaweed in Spain?
Invasive seaweed such as Rugulopteryx okamurae is spreading rapidly along Spain’s coastlines. It outcompetes native species, damages biodiversity, and affects fisheries and tourism. Once established, these invasive species are difficult to control due to their reproductive capacity and lack of natural predators.

How do shipwrecks contribute to marine pollution?
Shipwrecks, like the recent incident off Sri Lanka, release pollutants such as oil, chemicals, and debris into the ocean. These accidents threaten marine ecosystems, contaminate water sources, and pose legal and environmental challenges for cleanup efforts.
-
What role does climate change play in marine ecosystem decline?
Climate change causes ocean warming, acidification, and sea level rise, all of which disrupt marine habitats. These changes lead to more frequent and severe marine crises, including algal blooms, species invasions, and habitat loss, putting global marine biodiversity at risk.
-
Can marine pollution be reversed or stopped?
While some pollution effects are reversible, many marine crises require concerted global efforts, policy changes, and pollution reduction strategies. Protecting marine ecosystems involves reducing plastic waste, controlling pollution sources, and addressing climate change at an international level.
