Environmental Risks
Definition: Potential hazards to ecosystems and human health arising from anthropogenic activities, including chemical spills, air pollution, and radioactive contamination.
Key Categories
- Chemical Pollution: Industrial runoff, pesticides, and plastic waste.
- Air Quality: Greenhouse gases, particulate matter, and ozone depletion.
- Radioactive Contamination: Nuclear waste, accident byproducts, and legacy military hazards.
Radioactive Legacy Risks
Sunken Nuclear Submarines
- Approximately 150 nuclear submarines operate globally; a significant number were lost during the Cold War.
- Threat Profile: Sunken vessels pose serious environmental threats due to leaking Nuclear Fuel and radioactive components corroding on the seabed.
- Management Strategies:
- Continuous monitoring of hull integrity and radiation levels.
- Complex salvage operations to retrieve hazardous materials.
