Which of the following is not true?

Answer & explanation

Correct answer: option 4

The correct answer is Option (4) → Humans are not the cause of global pollution.

Option (1) The loss of biodiversity continues due to the destruction of habitat. — True. The loss of biodiversity continues due to the destruction of habitat in areas which are rich in species.

Option (2) Decline in ozone is a danger to ecosystems and human health. — True. A steady decline in the total amount of ozone in the Earth’s stratosphere, the ozone hole, poses a real danger to ecosystems and human health.

Option (3) Coastal pollution is increasing globally. — True. Coastal pollution too is increasing globally: the coastal waters are becoming increasingly polluted.

Option (4) Humans are not the cause of global pollution. — False. The coastal waters are polluted largely due to land-based activities, and intensive human settlement of coastal zones will further harm the marine environment: human activity is a cause of pollution.

NCERT (2026-27): “Environmental Concerns in Global Politics … Natural forests — which help stabilise the climate, moderate water supplies, and harbour a majority of the planet’s biodiversity on land— are being cut down and people are being displaced. The loss of biodiversity continues due to the destruction of habitat in areas which are rich in species. A steady decline in the total amount of ozone in the Earth’s stratosphere (commonly referred to as the ozone hole) poses a real danger to ecosystems and human health. Coastal pollution too is increasing globally. Although the open sea is relatively clean, the coastal waters are becoming increasingly polluted largely due to land-based activities. If unchecked, intensive human settlement of coastal zones across the globe will lead to further deterioration in the quality of marine environment.…”
