Explain the causes of noise pollution and suggest any three measures to overcome it.
Show Hint
Modern technology like "noise-canceling" materials can be used in building construction to reduce indoor noise.
Solution and Explanation
• Noise pollution is the presence of excessive or unwanted sound that causes discomfort and health issues for humans and animals.
• It is primarily an urban phenomenon associated with mechanization and transportation.
Step 1: Identify the causes of noise pollution
Traffic noise from the constant honking of automobiles and the roar of aircraft near airports is a major source.
Industrial machinery and construction activities using heavy drills and mixers create high-decibel sound levels.
The use of loudspeakers during festivals, public meetings, and loud music in commercial areas contributes significantly to community noise.
Step 2: Suggest measures to overcome it
Regulatory measures: Strict enforcement of "Silence Zones" around hospitals, schools, and residential areas during nighttime.
Acoustic planning: Installing sound barriers or "noise buffers" (like rows of trees) along highways and near industrial zones.
Public Awareness: Educating citizens about the harmful effects of unnecessary honking and the restricted use of high-decibel firecrackers and loudspeakers.

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.
