You might be right to question what kind of impact our reading habit makes on the environment! It’s not as easy as saying: “e-books are always better.” Take a detailed look:
Paper Books:
Pros:
Durable: Can last for generations.
Screen-free: It’s kinder on the eyes during low-light conditions.
Tactile: The feel of holding and turning pages can be a pleasurable experience while reading.
Cons:
Deforestation: To produce paper, trees have to be cut down.
Excessive use of Water: Some paper work uses colossal quantities of water.
Transportation: Books must be transported that increases carbon footprint.
Waste: There is potential waste from discarded books which can help towards the landfill.
E-readers:
Advantages
No Deforestation: No cutting down of trees to get paper is involved.
Less Transport: You can download your e-books electronically which reduce transport.
Less Waste: E-readers hold thousands of books such that there is no need for physical storage.
Disadvantages:
Manufacturing Impact: Manufacturing e-readers uses electricity and resources as well as such minerals which prove to be harsh on the earth.
E-waste: Unsold e-readers become the part of electronic waste which might be dangerous most of the times unless disposed and recycled in time.
Energy Used: E-readers work only on electricity whose source can sometimes be fossil fuels.
Too Much Screen Time Harms Sleep Pattern and Vision System.
Heavy Reader: If you read many books, e-readers tend to be less environmentally impactful.
Occasional Reader: If you read a book every now and then, then paper books may be more environmentally friendly.
Determining Factors: Find the number of books you tend to read, the kind of energy source powering your devices, and eco-friendly disposal practices for both the book and e-reader.
Beyond the Choice:
Knowledge of the Environmentally Friendly Options:
Buying secondhand books.

See less-Soil Health: Practices such as no-till farming, cover cropping, and crop rotation are helpful in the improvement of soil structure, growth of organic matter, and water retention. A healthy soil stores a lot of carbon which rids the air of carbon dioxide and helps to moderate global warming.
-Water conservation by techniques like drip irrigation and rain harvesting are more efficient, therefore, using water less and keeping water clean.
Less Chemical Use
-IPM: The application of natural enemies in a smart way, such as rotation, other naturally occurring predators, and organic control, only increase the growth of biodiversity and the least amount of water pollution and this is the reasons why fewer pesticide are used.
-Less Use of Fertilizers: Using organic fertilizers and less chemical ones helps diminish the nutrient runoff and enhance the soil capacity to store nutrients in every way.

Public discourse continues to explore the possibility of an Arctic “scramble,” as if it were some kind of a 19th-century scramble for Africa.
Anti-Scramble for the Arctic:
There are high reserves of oil, gas, minerals, and fisheries in the Arctic, giving the region a big resource potential and making it one of the more interesting regions in which to extract resources.
In some sense, they are strategic avenues because they account for the meltage of the ice with sea and now one can take easier routes between Asia and Europe within less time while at the same time saving many costs. Very high international power competition is prevalent once again today, and many countries will battle to prove some relevance in such a region today.
-Climate Change: Climatic changes have altered the Arctics conditions so fast. This means vast opportunities exist there for extracting its resources and traversing its ocean routes, also spurring an element of contest for controlling this region.
Points Against a “Scramble for the Arctic”:
-International Cooperation: Through the inter-governmental Arctic Council, it is highly successful for building cooperation within the Arctic countries in terms of environmental protection, sustainable development etc.
Environmental Concerns: The Arctic is an extremely fragile system that easily falls victim to environmental destruction. International concern about the preservation of the Arctic environment and responsible development is rapidly on the rise.
Indigenous Peoples’ Rights: The rights and interests of indigenous peoples in the Arctic region are increasingly acknowledged and respected.
-Economic and Technological Challenges: Developing in the Arctic environment presents serious economic and technological challenges that could limit the speed of development.
Conclusion
Although the site and potential for conflict and competition over the Arctic region do exist, it is unlikely to be a direct replica of the 19th-century scramble for Africa. The factors that are likely to influence the future of the Arctic region include international cooperation, environmental concerns, and the rights of indigenous peoples.

Model Answer
Introduction
Non-conventional energy sources, also known as renewable energy sources, are essential for India’s energy security. These sources, including solar, wind, hydro, and biomass, are sustainable, environmentally friendly, and naturally replenishing. Their role is becoming increasingly significant in supplementing the country’s existing hydrocarbon resources.
Role in Energy Security
Non-conventional energy sources, such as solar and wind, contribute to diversifying India’s energy mix. As of 2021, renewable energy accounted for 24% of India’s total installed power capacity, with solar and wind power leading the way. The government’s target to achieve 175 GW of renewable energy capacity by 2022, including 100 GW from solar and 60 GW from wind, highlights the growing importance of these sources.
By utilizing non-conventional energy, India can reduce its dependency on imported hydrocarbons. Currently, India imports over 80% of its crude oil and around 45% of its natural gas needs. Solar power projects in states like Rajasthan, Gujarat, and Tamil Nadu are already helping reduce reliance on coal-fired power and imported coal.
Non-conventional energy sources contribute significantly to environmental sustainability by reducing greenhouse gas emissions. For example, India’s renewable energy capacity has helped avoid approximately 49 million tons of CO2 emissions annually, showcasing the environmental advantages over traditional hydrocarbon resources.
Complementing Hydrocarbon Resources
Conclusion
Non-conventional energy sources are crucial in ensuring India’s energy security. By complementing the country’s hydrocarbon resources, they pave the way for a cleaner, greener, and more sustainable energy future.
