Explain the causes of air pollution and suggest any three measures to overcome it.
Show Hint
Switching to renewable energy sources like solar and wind is the long-term solution to air pollution.
Solution and Explanation
• Air pollution is the contamination of the atmosphere by harmful gases, dust, and smoke that affect human health and the environment.
• It is a significant challenge in urban and industrial regions across the world.
Step 1: Identify the causes of air pollution
Combustion of fossil fuels in transport vehicles and thermal power plants releases carbon monoxide, sulphur dioxide, and nitrogen oxides.
Industrial processes, especially in cement, chemical, and metallurgical industries, release particulate matter and toxic fumes.
Agricultural practices, such as the burning of crop residues (stubble burning), contribute significantly to smog and poor air quality in North India.
Step 2: Suggest measures to overcome it
Transition to cleaner fuels: Promoting the use of Electric Vehicles (EVs) and Compressed Natural Gas (CNG) to reduce vehicular emissions.
Emission Control: Installing scrubbers and filters in industrial chimneys to trap harmful particulates before they reach the atmosphere.
Increasing Green Cover: Massive afforestation and the development of urban green belts to act as natural air purifiers.

Read the passage carefully and answer the questions that follow:
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.
