The importance of greenhouse effect lies in the fact that it helps to keep the Earth warm. The key aspect to understand is that greenhouse gases trap heat in the atmosphere. Otherwise, it would be a really cold place to live.
Sunlight is that form of energy that the Earth gets from the sun. It absorbs some of it which results in heating up. The Earth also gives off energy which is realized in the form of infrared radiation. In such a way, it helps the Earth to cool down. However, not all of this radiation goes into outer space. Some of it is absorbed by the greenhouse gases in the atmosphere. As a result, the atmosphere gets warmer.
What is significant to remember is that the greenhouse effect makes it possible to live life in the way we know it. However, the natural process of greenhouse effect gets intensified by the burning of fossils and deforestation which results in global warming. The issue has become a worldwide problem these days.
