APES Human Impacts on Wetlands and Mangroves

How do wetlands improve water quality?

• They absorb all pollutants without filtering them.

• They filter pollutants and sediments from water, improving overall water quality and providing cleaner water for ecosystems and human use.

• They increase the temperature of the water, which helps in evaporation.

• They provide habitats for fish but do not affect water quality.

What are wetlands?

• Areas where water covers the soil, either permanently or seasonally, and support aquatic plants, including marshes, swamps, and bogs.

• Dry areas with little vegetation and high temperatures.

• Regions characterized by high altitudes and low temperatures.

• Urban areas with significant human development and infrastructure.

How do urban development activities impact wetlands?

• They enhance the ecological functions of wetlands.

• They lead to the destruction of wetlands by draining them for construction purposes.

• They have no impact on wetlands.

• They create new wetlands in urban areas.

What are mangroves?

• Coastal ecosystems characterized by salt-tolerant trees and shrubs that grow in intertidal zones, providing habitat for diverse wildlife.

• A type of freshwater forest found in river deltas.

• A desert ecosystem with cacti and succulents.

• A type of grassland found in temperate regions.

What is the impact of climate change on wetlands?

• Climate change has no effect on wetlands.

• Climate change can lead to rising sea levels, increased flooding, and altered precipitation patterns, threatening wetland ecosystems.

• Climate change only affects terrestrial ecosystems, not wetlands.

• Climate change improves wetland ecosystems by increasing biodiversity.

What is the significance of the Florida Everglades?

• It is a major urban area in Florida.

• It is a unique wetland ecosystem known for its biodiversity and is a successful example of wetland restoration.

• It is a popular tourist destination for its beaches.

• It is primarily known for its agricultural production.

• Increased urban development

• Higher property taxes

• Decreased biodiversity

What is carbon sequestration?

• Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide, which wetlands and mangroves help achieve.

• Carbon sequestration is the method of releasing carbon dioxide into the atmosphere to promote plant growth.

• Carbon sequestration refers to the process of converting carbon dioxide into oxygen through photosynthesis.

• Carbon sequestration is the technique of using carbon-based fuels to generate energy.

What role do wetlands play in flood control?

• Wetlands release excess rainwater into rivers, increasing flood risk.

• Wetlands absorb excess rainwater and reduce runoff, helping to control flooding and protect surrounding areas.

• Wetlands have no impact on flood control.

• Wetlands only serve as habitats for wildlife and do not affect flooding.

What are the effects of pollution on wetlands and mangroves?

• Pollution can lead to improved water quality and increased biodiversity.

• Pollution can contaminate water with harmful substances, leading to reduced water quality, loss of biodiversity, and harm to plant and animal species.

• Pollution has no significant impact on wetlands and mangroves.

• Pollution can enhance the growth of certain plant species in wetlands.
