Questions and Answers
Which agricultural practice primarily helps reduce water pollution from artificial pesticides?
Which agricultural practice primarily helps reduce water pollution from artificial pesticides?
- Implementing flood irrigation to dilute pesticide concentration in fields.
- Using genetically modified crops that are resistant to pests, thus reducing pesticide use. (correct)
- Applying pesticides in larger quantities to ensure complete coverage.
- Applying pesticides more frequently, preventing pest populations from becoming too large.
In the context of oil spills, what is the primary function of booms and skimmers?
In the context of oil spills, what is the primary function of booms and skimmers?
- To contain the oil spill and prevent it from spreading, while physically removing oil from the water's surface. (correct)
- To chemically neutralize the oil, breaking it down into harmless substances.
- To sink the oil to the bottom of the ocean, keeping it away from sensitive shoreline ecosystems.
- To dilute the oil, reducing its concentration and impact on the environment.

Study Notes
- Manure is an organic fertilizer used to boost plant growth.
Reducing Water Pollution
- Organic fertilizers release nutrients slowly into the soil, allowing plants to absorb them and reducing runoff into water bodies.
- Planting vegetation around agricultural fields can reduce agricultural water pollution.
- Plants bordering fields absorb excess nutrients from runoff.
- Plant roots help reduce soil erosion and prevent soil from washing into waterways.
- Reduced tilling and plowing frequency also reduces soil erosion.
- Proper management of livestock waste reduces water pollution.
- Keeping animals away from bodies of water and treating their wastes prevents runoff.
Cleaning Up Oil Spills
- Oil spills must be removed from oceans to minimize ecological damage.
- Certain bacteria can break down spilled oil.
- Mechanical containment methods using booms and skimmers are used in oil spill clean up.
- Booms are floating objects confining the spilled oil area and preventing oil molecules from reaching the shore.
- Skimmers work like vacuums by collecting the oil from areas confined by booms, which allows the capture and storage of spilled oil for proper disposal.
- Solidifiers change the state of oil spills from a liquid to solid or semisolid rubberlike substances, which can then be removed from the water.
Preserving Irrigation Water
- Farmers can manage water usage for irrigation to minimize water use.
- Replacing hoses with sprinklers can minimize water usage for irrigation purposes.
- Irrigation systems use automated timers to set irrigation time and duration.
- Some irrigation systems use sensors for soil moisture and rain turning on and off automatically according to plant needs.
- Drip irrigation involves slowly dripping water directly to root zones through tubing.
- Drip irrigation minimizes water loss.
Controlling Emissions from Industries and Vehicles
- Factories release air pollutants through smoke.
- Smokestacks can be equipped with scrubbers to reduce air pollution, scrubbing sprays toxic emissions with mist, trapping pollutant molecules in steam droplets, which get collected in a filter.
- Scrubbers reduce emissions of air pollutants like sulfur dioxide, oxides of nitrogen, carbon dioxide, and suspended particles are through filtering.
- Vehicles emit air pollutants, which can be reduced by installing catalytic converters in exhaust systems.
- Catalytic converters reduce the emission of air pollutants like nitrogen oxides, carbon monoxide, and unburned hydrocarbons by filtering.
- Public transportation reduces the number of polluting vehicles.
- Ultra-low-sulfur diesel fuel reduces harmful sulfur dioxide emissions compared to standard diesel.
