Private monopoly, higher prices, worse quality.
Lack of info and heavy investments.
Regulation failure and less tax revenue.
Lack of freshwater to meet demand.
Water use habits and standards.
Physical (lack of water) and Economic (lack of infrastructure).
Population growth, economic activity, less rain, evaporation, pollution, poor management.
Too little rain, too much evaporation, poor soil water retention.
Most water is salty; accessible freshwater is very limited.
It increased with population and economy growth.
Overuse, climate change, pollution, and poor management.
Shipping noise, seismic airguns, pile driving, low-flying planes, oil drilling, offshore wind turbines, dynamite fishing.
Stress in marine animals, disrupted whale movement, reduced communication, changed predator behavior.
Better maintenance, improved propeller design, focusing on noisiest ships, slowing speed.
Wastewater with feces, urine, nutrients, viruses, plastics polluting oceans.
Old infrastructure, cruise ships dumping, floods, poor treatment, lack of sanitation.
Eutrophication, algal blooms, coral harm, destroyed mangroves, disease spread, fish death.
Green infrastructure, better sewage systems, wetlands, reed beds to clean water.
Oil spills, refuelling leaks, pipeline breaks, shipping, dumping.
BP cost $65 billion for damages.
Kills marine life, suffocates fish, coats birds, blocks light, causes health problems.
Contain with booms, skim oil, manual clean-up, protect wildlife (only 40% cleaned).
Noise, collision risk, oil spills, ballast water harm, climate emissions.
Waste, pollution, reef damage by boats and divers, harmful wildlife interactions.
Extracting minerals from ocean floor with unknown environmental impacts.
Bycatch kills turtles, dolphins, seabirds; damages seabed and coral.
30% overfished, 60% at sustainable limits.
Max fish catch without harming fish population balance.
Max catch for several species considering ecosystem interactions.
Overusing shared resources causes depletion because everyone acts selfishly.
Damages ecosystems, food chain imbalance, food insecurity, local fishers lose income.
Large: more catch per worker. Small: more sustainable, less fuel, better for ecosystem.
Mangrove loss, water pollution, acidification, pesticide use.
Poor regulations, bad labor, water conflicts, harms small fishers.
Fish farming on land to reduce ocean harm, better disease control but costly.
More than 4 billion for at least one month.
Not enough water to meet all needs, often seasonal.
When 25%+ of renewable water is used.
Changes rainfall, water availability, and ecosystems.
About 685 million in 570+ cities.
