Overfishing is one of the most serious threats to marine life. When too many fish are caught, it can disrupt the food chain and damage the entire ecosystem. Overfishing can also lead to the extinction of certain species.
Pollution
Pollution from human activities, such as oil spills, sewage discharge, and plastic waste, can all have a negative impact on marine life. Pollution can kill fish and other marine animals, damage their habitats, and make them more susceptible to disease.
Climate change
Climate change is also having a major impact on marine life. Rising sea temperatures are causing coral reefs to bleach and die, and changing weather patterns are disrupting fish migration and breeding patterns. Climate change is also leading to ocean acidification, which can make it difficult for marine animals to build their shells and skeletons.
Habitat destruction
Habitat destruction is another major threat to marine life. When coastal areas are developed, it can destroy the habitats of fish, sea turtles, and other marine animals. Habitat destruction can also lead to the extinction of certain species.
Introduced species
Introduced species, such as the lionfish in the Caribbean, can compete with native species for food and resources. Introduced species can also transmit diseases to native species.
