Impact of climate change on coastal communities

Answer 4

Protecting mangroves:
- Globally, 50% of all mangrove forests have been lost since 1950

Food:
- 500 million of the poorest people on Earth rely on fisheries for food and income
- Climate change is altering the distribution and productivity of species
- Coral reefs provide shelter for 25% of marine animals, however acid acidification and warming climate is leading to coral bleaching, negatively impacting the local food source for coastal areas

Tourism:
- Higher water temperatures in 2016 caused bad coral bleaching of the Great Barrier Reef. Coral reefs are tourist attractions, but damage to the coral can negatively impact the locals that rely on tourism
