Trapping of thermal radiation in our atmosphere by gases present in it, is called the greenhouse effect. In the recent years, a gradual increase in the heat trapped in the atmosphere has resulted in global warming. Do you think greenhouse effect itself is a harmful phenomenon? Give reasons for your answer.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Greenhouse Effect**: The greenhouse effect is a natural process where certain gases in the Earth's atmosphere, known as greenhouse gases (like carbon dioxide, methane, ozone, and water vapor), trap thermal radiation from the sun. This process helps to maintain the Earth's temperature, making it habitable.

2. **Role of Greenhouse Gases**: Greenhouse gases absorb and emit infrared radiation. When sunlight reaches the Earth, some of it is reflected back to space, while the rest is absorbed and re-radiated as heat. Greenhouse gases trap some of this heat, preventing it from escaping into space.

3. **Importance of the Greenhouse Effect**: Without the greenhouse effect, the Earth would be too cold for life as we know it. It is essential for maintaining a stable climate and supporting ecosystems.
