6. List three major problems related to sustainable development.
Answer: Three major problems related to sustainable development are-climate change, poverty, and environmental degradation. These issuses are interconnected and require a holistic approach for effective solutions.
1. Climate Change: Human activites, particularly the burning of fossil fuels, are causing a rise in greenhouse gas emissions, leading to global warming and climate change. This has significant consequences like rising sea levels, extreme weather events, and disruptions to ecosystems, impacting both human populations and natural environments.
2. Poverty: A significant portion of the world's population still lives in poverty, lacking access to basic necesssities like food, clean water, healthcare, and education. Poverty and inequality hinder sustainable development, making it harder for people to improve their living conditions and contribute to a sustainable future.
3. Environmental Degradation: Unsustainable practices like deforestation, overfishing, pollution, and excessive resource consumption are leading to the depletion of natural resources and the degradation of ecosystems. This includes the loss of biodiversity, pollution of air and water, and the destruction of habitats, which negatively impacts both human well being and the health of the planet.
7. List three long term solutions to sustainable development.
Answer: Three long term solutions for sustainable development are:
1. Renewable Energy Transition: Shifting away from fossil fuels and towards renewable energy sources like solar, wind, geothermal, and biomass is crucial for reducing greenhouse gas emissions and mitigating climate change.
2. Circular Economy: Adopting circular economy principles involves designing products for longevity, reuse, and recyclability, minimizing waste generation, and promoting resource efficiency. This approach contrasts with the traditional linear " take-make-dispose" modle and offers long-term economic, social, and environmental benefits.
3. Sustainable Agriculture: Practices like agroforestry, precision agriculture, and reduced tillage can improve soil health, water management, and biodiversity, while also enhancing crop yields and reducing the environmental impact of food production.
