Part 1 of 3
Key concepts
3 concepts
- 1
Rising atmospheric carbon dioxide leads to ocean warming, stressing marine organisms and causing coral bleaching, and also results in ocean acidification, which impacts shell formation.
- 2
Pollution, including plastic debris and chemical pollutants, harms wildlife, while nutrient runoff from agriculture creates hypoxic 'dead zones'.
- 3
Overfishing depletes fish stocks and disrupts trophic cascades, and habitat destruction, like clearing mangrove forests, removes vital nursery grounds.
Part 2 of 3
Practice
