The environment is everything that is around us. It can be living or non-living things. It includes physical, chemical and other natural forces. Living things live in their environment. They constantly interact with it and adapt themselves to conditions in their environment. In the environment, there are different interactions between animals, plants, soil, water, and other living and non-living things.


In biology and ecology, the environment is all of the natural materials and living things, including sunlight.  If those things are natural, it is a natural environment. The environment includes the living and nonliving things that an organism interacts with or has an effect on it.

Global Warming:

Global Warming refers to the increasing temperature of the Earth’s climate system and its related effects. Scientific evidence has conclusively proven that the Earth’s temperature is in fact rising and has risen by 0.85oC. This has an impact has affected different regions differently. The effects include rising sea levels, retreating glaciers, loss of sea ice in the poles, warming global temperatures, changing precipitation, expansion of deserts etc.

Climate is a long-term weather trend affecting human lives positively or negatively. Climate change is the long-term variations in the weather patterns. Climate itself adjusts time to time, however, going at a wrong path for many years because of regular loss of huge ice sheets. Earlier the earth atmosphere was covered with ice sheets which were able to make the earth atmosphere cool by preventing the earth from heat and sending back extra heat out of the space from the earth.

Sun is the ultimate source of heat energy which fuelling the weather systems after reaching to the earth. Earlier the harsh and extended bitter cold season was called as the little ice age which was due to the huge level variations in the solar activity. It is found that the positive human activities may play major roles in shaping earth’s climate. Such huge variations in the climate may lead to the danger of the human lives.

According to the Intergovernmental Panel on Climate Change (IPCC), the increase in earth’s average surface temperature by 20th century has been approximately 0.6°C. It has also been recorded in the northern hemisphere over the last century that there is a decrease in snow cover by 10 percent, decrease in spring and summer sea-ice by 10-15 percent, increases in rainfall and its intensity, huge level change in shifts of ice freezes and breaks up in the rivers and lakes.

Green House Effect:

Greenhouse effect plays an important role in the rising temperature. And hence to restrict global warming we need to limit the greenhouse effect and the gaseous emissions that cause the greenhouse effect.
