Question 1: What is renewable energy? Provide an example.

Answer: Energy from sources that naturally replenish, e.g., wind power.

Question 2: Define 'resource depletion' and give an example.

Answer: The reduction of a resource faster than it can be replenished, e.g., overfishing of cod in the North Atlantic.

Question 3: Name two renewable resources commonly used in the UK.

Answer: Wind and solar energy.

Question 4: What is sustainable development?

Answer: Development that meets present needs without compromising future generations.

Question 5: Give an example of a sustainable resource management practice.

Answer: Reforestation projects in the Amazon rainforest.

Question 1: Which country is a leader in offshore wind energy production?

Answer: Denmark

Question 2: Name one challenge associated with increasing renewable energy use.

Answer: Intermittency of energy supply.

Question 3: What is the main cause of water scarcity in parts of California?

Answer: Drought conditions combined with overuse of water resources.

Question 4: Identify one policy used in the UK to promote sustainable resource use.

Answer: The Feed-in Tariff scheme for renewable energy.

Question 5: Name a natural resource that is being overexploited globally.

Answer: Fisheries, such as cod stocks.

Question 1: Based on the California case study, identify two impacts of water scarcity on local communities.

Answer: Reduced agricultural productivity and increased risk of wildfires.

Question 2: Describe one sustainable solution implemented in California to address water shortages.

Answer: Implementation of water recycling and desalination projects.

Question 3: Explain how water management policies can help balance economic and environmental needs in California.

Answer: Effective policies promote efficient water use, incentivize conservation, and support sustainable practices, thereby reducing environmental strain while maintaining agricultural and urban development.

Question 4: Analyse the role of government regulation in promoting sustainable water use in California.

Answer: Government regulations enforce water restrictions, incentivize the adoption of sustainable technologies, and fund projects like water conservation initiatives, all of which help reduce overexploitation and support long-term water security.

Question 1: Explain the causes of overfishing in the North Atlantic Ocean.

Answer: Overfishing results from high demand for fish, advanced fishing technology, lack of effective regulation, and subsidies that encourage extensive fishing activities.

Question 2: Analyse how climate change impacts the availability of renewable resources like water and wind.

Answer: Climate change leads to altered weather patterns, increasing droughts and reducing wind speeds, which diminish the potential for renewable energy generation and affect water supply reliability, challenging sustainable management.

Question 3: Explain why sustainable resource management is essential for future environmental stability.

Answer: It ensures the long-term availability of resources, prevents environmental degradation, supports biodiversity, and helps mitigate climate change impacts.

Question 1: To what extent have renewable energy initiatives in Denmark contributed to sustainable resource management? Justify your answer.

Answer: Renewable energy initiatives in Denmark have significantly contributed by reducing reliance on fossil fuels, decreasing greenhouse gas emissions, and creating green jobs. However, challenges such as intermittency and high costs of infrastructure pose limitations. Overall, these initiatives represent a major step towards sustainability, but ongoing technological and policy improvements are necessary for full effectiveness.

Question 2: Evaluate the effectiveness of current policies in promoting sustainable water use in California.

Answer: California’s policies, including water restrictions and investments in recycling, have improved water conservation. Nonetheless, enforcement challenges, climate variability, and competing demands from agriculture and urban areas limit their overall effectiveness. A comprehensive, adaptive approach combining regulation, technology, and community engagement is essential for long-term success.
