Offshore drilling is the primary source of oil pollution in the ocean, accounting for about 30% of all oil spills.

Oil pollution can have a variety of negative effects on marine life, including death, disruption of food chains, and damage to coral reefs. However, it does not typically lead to increased reproduction rates.

Biodegradation is the process by which oil is broken down by microorganisms in the environment. This is a natural process that can take several months or years to complete.

Increasing cargo weight is not a strategy for reducing air pollution from ships. In fact, it can actually lead to increased emissions, as ships need to burn more fuel to move the heavier load.

Vehicle emissions are the main cause of air pollution in urban areas. Cars, trucks, and buses release a variety of pollutants into the air, including nitrogen oxides, carbon monoxide, and particulate matter.

Air pollution can have a variety of negative health effects, including respiratory problems, heart disease, and cancer. However, it does not typically lead to improved immune function.

Deposition is the process by which air pollutants are removed from the atmosphere and deposited on the ground or water. This can occur through wet deposition (rain or snow) or dry deposition (settling of particles).

Increasing plant capacity is not a strategy for reducing air pollution from power plants. In fact, it can actually lead to increased emissions, as the plant will need to burn more fuel to generate more electricity.

Agricultural activities are the main cause of air pollution in rural areas. These activities can release a variety of pollutants into the air, including ammonia, nitrogen oxides, and particulate matter.

Air pollution can have a variety of negative health effects on children, including asthma, reduced lung function, and increased risk of infections. However, it does not typically lead to improved cognitive development.

Chemical reactions are the process by which air pollutants are transformed into new compounds in the atmosphere. These reactions can occur between pollutants themselves or between pollutants and other compounds in the air.

Increasing home size is not a strategy for reducing air pollution from residential heating. In fact, it can actually lead to increased emissions, as the larger home will require more energy to heat.

Cooking and heating with biomass fuels (such as wood, charcoal, and dung) is the main cause of air pollution in developing countries. These fuels release a variety of pollutants into the air, including particulate matter, carbon monoxide, and nitrogen oxides.

Air pollution can have a variety of negative health effects on the elderly, including heart disease, stroke, and cancer. However, it does not typically lead to improved immune function.
