CASE 12 OCEAN HEALTH
ocean health
| Question | Answer |
|---|---|
| ocean health | overall condition of the marine environment: biodiversity, water quality, ecosystem resilience, and the sustainability of resources. |
| ocean health involves | It involves assessing the impacts of various stressors such as pollution, overfishing, climate change, and habitat destruction on the health and functioning of marine ecosystems.” |
| importance of oceans | - livelihoods - food nutrition - trade - surface mapping - critical minerals → for us to make national security products → manganese nodules for electric cars and solar panels - earth climates → absorb CO2 and regenerate Oxygen - living creatures |
| threats for ocean health | Climate change overfishing Habitat destruction - Pollutions. chemicals and trash, primarily originating from land sources and washed or blown into the ocean. marine shipping, offshore operations, and waste disposal accounting for the rest. |
| causes of ocean health | Causes: rapid industrialization, increased chemical and plastic production, chemically intensive agriculture, inadequate waste management |
| effects of ocean health | increased pathogenic bacteria, viruses, parasites, eutrophication, HAB |
| Harmful Algal blooms ( HABs) | large, rapid increases in population of algae in aquatic environments.but some produce toxins that can have detrimental effects on marine ecosystems. |
| Harmful Algal Blooms ( HABs ) | rapid proliferation of microalgae, cyanobacteria, or macroalgae in aquatic environments. |
| What is the impact of climate change on Harmful Algal blooms | - Impact of Climate Change: Warming temperatures and altered precipitation patterns can influence nutrient cycling and oceanographic conditions, potentially exacerbating HAB events |
| What is the anthropogenic Influences on HABs | Anthropogenic Influences on HABs: Eutrophication (excessive nutrient inputs), Habitat Destruction (loss of coastal habitats like mangroves) |
| What is the policies regarding Harmful Alhal Blooms | monitoring: detecting and tracking such as satellite imagery, sampling, biological monitoring: Regulatory measures, including shellfish harvesting closures and water quality standards GEOHAB and GlobalHAB facilitate international collaboration |
