Which is a correct environmental effect of population growth?

Correct answer: Increase in pressure on land and water

Direct answer: A, increased pressure on land and water. A larger population generally needs more space for housing, farming, roads and other activities, as well as more water for drinking, sanitation, agriculture and industry. This can place greater pressure on these environmental resources, especially when use is not carefully managed. Option A is correct because land and water are natural resources affected by human demand. Option B is wrong because a clock’s shape is unrelated to population growth. Option C is wrong because the number of lines in a book does not describe an environmental effect. Option D is wrong because changing a mountain’s name is a cultural or administrative action, not a direct environmental effect. Population growth does not produce exactly the same result everywhere, but resource pressure is a valid possible effect. Memory cue: more people generally mean greater demand for land and water.
