"The conventional sources of energy need to be replaced due to their exhaustibility." Justify the statement with suitable arguments.
Show Hint
Solution and Explanation
Conventional energy sources primarily refer to fossil fuels like coal, petroleum, and natural gas.
Step 2: Meaning
These fuels are finite, highly polluting, and take millions of years to form, making their current rate of consumption completely unsustainable.
Step 3: Analysis
• Conventional fossil fuels take millions of years to generate geologically, yet they are being consumed at a rate far exceeding their natural replenishment.
• Driven by rapid global industrialization and massive population growth, the known reserves of these finite fuels are depleting at an alarming pace.
• Beyond depletion, the combustion of these fuels releases massive quantities of toxic greenhouse gases, causing severe environmental pollution and accelerating global warming.
• Transitioning to inexhaustible renewable sources is the only way to ensure long-term energy security while halting ecological collapse.
Step 4: Conclusion
The inherent finite nature and severe environmental toxicity of conventional fuels make their total replacement a necessity for the future. Final Answer: Conventional energy sources like coal and petroleum must be urgently replaced because their finite reserves are depleting rapidly under high industrial demand, and their widespread combustion causes severe environmental pollution and global warming.

Hunting and Food Gathering
The earliest human beings depended on their immediate environment for their sustenance. They subsisted on: (a) animals which they hunted; and (b) the edible plants which they gathered from forests in the vicinity. Primitive societies depended on wild animals. People located in very cold and extremely hot climates survived on hunting. The people in the coastal areas still catch fish though fishing has experienced modernisation due to technological development. Many species, now have become extinct or endangered due to illegal hunting (poaching). The early hunters used primitive tools made of stones, twigs or arrows so the number of animals killed was limited. Gathering and hunting are the oldest economic activity known. These are carried out at different levels with different orientations. Gathering is practised in regions with harsh climatic conditions. It often involves primitive societies, who extract both plants and animals to satisfy their needs for food, shelter and clothing. This type of activity requires a small amount of capital investment and operates at very low levels of technology. The yield per person is very low and little or no surplus is produced.- Examine the role of climate, water availability, and soil fertility on the distribution of world population.
