Pollution
Pollution means contamination of our surroundings that toxifies air, water, soil, etc. due to the presence of harmful
substances that have an adverse effect on living organisms. Human activities like urbanisation, industrialisation,
mining, and exploration are the reasons of global environmental pollution which has severe long term consequences.
The different types of pollution are:
• Air Pollution: It is mixing of harmful gases in the air surrounding us that harm the health of humans, animals and
plants. Human activities deplete the air quality and cause global warming and climate change of this mother Earth.
• Water Pollution: It is contamination of water bodies like streams, rivers, oceans, etc. due to mixing of harmful
chemicals rendering it toxic for plants and animals residing in these water bodies. This is a serious threat since 70%
of our earth is covered with water.
• Soil Pollution: Soil is a mixture of both living and non living matter such as air, water, mineral and decaying organic
matter. Soil Pollution is contamination of soil due to presence of pollutants or chemicals which are toxic for plants
and animals living in that area. Some pollutants are naturally accumulated in soil due to precipitation. Some are
accumulated due to human activities.

Global Warming
Global Warming is an increase in the average temperature of the earth mainly due to greenhouse gases (mainly carbon
dioxide) produced by a lot of human activities. It has resulted in melting of glaciers, rising sea level and intense heat
waves all across the globe. It is one of the major environmental issues as it creates an ecological imbalance and has
become a reason for the extinction of many plant and animal species. Main causes of global warming are:
