Front

What is overfishing?

Back

Overfishing is the practice of catching fish at a rate faster than they can reproduce, leading to a decline in fish populations.

Front

What is nonpoint source pollution?

Back

Nonpoint source pollution refers to contaminants that enter water bodies from multiple, diffuse sources rather than a single, identifiable source.

Front

What is leachate?

Back

Leachate is a liquid that has percolated through a solid and leached out some of the constituents, often a concern in landfills as it can contaminate groundwater.

Front

What is runoff?

Back

Runoff is the flow of water, usually from precipitation, that moves across the land surface and can carry pollutants into water bodies.

Front

What is percolation?

Back

Percolation is the process by which water moves downward through soil and rock layers, which can transport agricultural pollutants to groundwater.

Front

What is the impact of fertilizers on algae growth?

Back

Fertilizers can lead to nutrient pollution, which promotes excessive algae growth in water bodies, resulting in harmful algal blooms.

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new habitat, often disrupting local ecosystems.

Front

What is methane?

Back

Methane is a potent greenhouse gas produced during the decomposition of organic matter in landfills, which can be harnessed for energy.

Front

What is the significance of returning non-adult fish to the ocean?

Back

Returning non-adult fish allows them to grow and reproduce, helping to sustain fish populations and combat overfishing.

Front

What is the role of policing ships in regulating fishing?

Back

Policing ships enforce fishing regulations to prevent overfishing and ensure sustainable practices in marine environments.
