Unit 4 Ocean Issues and Resource Management

What are the various arguments for preserving species and habitats?

• Biodiversity, economic gain, visual appeal, ethical responsibility
• Geographical location, recreational use, legal requirements, moral responsibility
• Economic potential, governmental interests, cultural significance, ethical concern
• Biological factors, international treaties, historical importance, ecological curiosity

Which factors influence the design of protected marine areas?

• Elevation, land use, urban development, human migration
• Site selection, networking, seasonal factors, governmental policies
• Replication, aesthetics, cultural history, social dynamics
• Biodiversity, recreational activities, species evolution, climate change

What strategies can be employed to support marine ecosystem health?

• Implementing artistic programs, distributing free food, promoting recreational fishing, constructing monuments
• Establishing tourist attractions, facilitating shipping lanes, designing waterfront properties, encouraging large-scale agriculture
• Managing threats, zoning, permitting, longitudinal monitoring
• Building luxury resorts, introducing exotic species, increasing industrial shipping, constructing offshore energy platforms

When evaluating the success of a marine protected area, what factors should be considered?

• Political influence, economic profit, recreational activities
• Coral diversity, fish populations, economic benefits
• Governmental policies, historical importance, aesthetic appeal
• Bureaucratic challenges, international relations, legal constraints

What distinguishes the roles of government and non-government organizations in ecosystem management?

• Governmental organizations focus solely on economic interests
• Non-government organizations lack political influence
• Government agencies tend to be slower in responding
• Non-government groups often prioritize recreational activities

How can future scenarios for marine systems be evaluated?

• By analyzing historical population data
• Through the study of cultural influences
• By examining economic reports from other industries
• By analyzing different atmospheric condition datasets

In what ways can historical geological data be compared with changes in land use practices?

• By analyzing historical population data
• Through the study of cultural influences
• By examining economic reports from other industries
• By comparing coral core data with land use practices and carbon dioxide levels

What are the indirect consequences of ocean acidification on the marine environment?

• Increased fish populations, reduced algae growth
• Enhanced coral growth, reduced sedimentation
• Declining phytoplankton, disrupted food chains
• Greater biodiversity, elevated oxygen levels

Which factors between the atmosphere and oceans drive weather patterns and climate?

• Ocean currents, fish migrations, wind direction
• Temperature, rainfall, solar radiation
• Soil composition, agricultural practices, geological formations
• Wind speed, barometric pressure, magnetic fields

How does the increase in average global temperature impact marine environments?

• It decreases ocean salinity and reduces wave heights
• It enhances the growth of coral reefs and sea grasses
• It has minimal impact on marine ecosystems
• It alters thermal regimes and changes oceanic chemical parameters
