Explanation

Deforestation reduces the number of trees that absorb CO₂ and release oxygen.

This leads to higher CO₂ levels, contributing to pollution and climate change.

Explanation

The three types of pollution are:

• Air Pollution: Harmful substances released into the air, like carbon monoxide and sulfur dioxide.
• Water Pollution: Contamination of water sources with pollutants such as industrial waste and sewage.
• Land Pollution: Degradation of land through activities like deforestation and improper waste disposal.
