Q.1	A team of environmental researchers embarked on an expedition to study the impact of rising temperatures on Arctic wildlife. During their research, they noticed a significant decline in the population of polar bears due to habitat loss caused by melting ice caps. Which of the following statements best describes the direct consequence of this decline in the polar bear population?
	a) Increased predation on seals by other Arctic predators		b) Reduced tourism opportunities in the Arctic region
	c) Increased scavenging on land by polar bears		d) Disruption of balance of Arctic marine food webs, impacting various species

Q.2	Consider the following statements and choose the correct option: Statement 1: Climate change impacts are predictable, and their effects remain constant across different regions and communities. Statement 2: Climate change mitigation involves adapting to its effects rather than reducing greenhouse gas emissions.
	a) Statement 1 is correct but statement 2 is incorrect.		b) Statement 1 is incorrect but statement 2 is correct.
	c) Both the statements are correct.		d) Both the statements are incorrect.

Q.3	Consider the case study given below and answer the following question: Case Study: The Müller Family's Journey to Renewable Energy The Müller family, residing in a charming village in the German countryside, had always been conscious about their environmental impact. In 2022, they decided to take an active step towards a greener lifestyle by installing a rooftop solar panel system. Their primary motivation was to reduce their reliance on fossil fuels and contribute to mitigating climate change. However, as they embarked on this journey, they discovered a plethora of other benefits: Environmental Benefits: -Reduced Carbon Footprint: The solar panels generated clean energy, leading to a significant reduction in their carbon emissions. This translated to a cleaner environment for their family, their community, and the planet. -Improved Air Quality: By relying less on fossil fuels, the Müllers contributed to cleaner air in their region, which improved their overall health and well-being. Financial Benefits: -Reduced Electricity Bills: The solar panels generate enough electricity to cover a significant portion of their household energy needs, resulting in substantial savings on their monthly electricity bills. This provided them with financial stability and freed up resources for other expenses. -Government Incentives: The German government offers various financial incentives for individuals and families adopting renewable energy solutions. The Müllers took advantage of these incentives, further reducing the cost of their solar panel system and accelerating their return on investment. Lifestyle Benefits: -Energy Independence: The Müllers achieved a sense of energy independence by generating their own clean energy. This gave them greater control over their energy consumption and reduced their dependence on the national grid, especially during peak hours. -Enhanced Home Value: Homes with renewable energy systems are becoming increasingly sought-after, leading to a potential increase in the value of the Müller's property. Overall Impact: The Müller family's experience showcases the numerous benefits of adopting renewable energy in a domestic setting. Their commitment to environmental sustainability not only helped them create a cleaner future but also resulted in financial savings and enhanced their quality of life. Their story serves as an inspiration for others to consider switching to renewable energy and contribute to a more sustainable future.
