Carbon neutral world and the role of forests and trees.

Climate change is the ultimate effect of huge carbon footprint individuals companies and countries. Greenhouse gases, whether natural or anthropogenic, contribute to the warming of our earth. From 1990 to 2005, carbon dioxide emissions increased by almost 30 percent. By 2008, the emissions had almost attributed to nearly 35 % increase in warming, as compared with 1990 levels. The last decade was the warmest decade on record worldwide, according to the U.S. Environmental Protection Agency's Climate Change Indicators Report. A carbon neutral world is the need of the hour.

Carbon emissions and other greenhouse gases are caused by the burning of fossil fuels in the environment. In fact, any activity to fulfill a human need requires energy that emits carbon dioxide. The electricity we use is mostly made from fossil fuels (such as coal, natural gas, and oil). The more electricity we use, there is more fossil fuel consumption leading to further increase in carbon dioxide and other GHG emissions. All emissions when putting together for a specific period of time is called carbon footprint. when the entire carbon footprint is made zero through emission reduction we call it carbon neutrality.

Most of the things we use are made in factories by the use of non-renewable resources. These are sent to far-flung areas from the freight trains that again involve burning of fossil fuels. This increases the carbon footprint of the products, in order to make them carbon neutral, efficiency measures and offsets shall be required. The process of becoming carbon neutral is called neutrality.

Whatever carbon dioxide was produced by humans before the industrial revolution was absorbed by surrounding forests and trees as the sources wherein balance with the sinks, so the carbon footprint of the world was in balance. Jungle, plants-trees absorb carbon dioxide and release oxygen back into the air thereby assisting in becoming carbon neutral and maintain carbon neutrality. With the beginning of the industrial era, fuel began to be used on a large-scale, leading to production of carbon dioxide in large quantities enhancing the carbon footprint and disbalancing carbon neutral state of the environment.

At the same time, forests, which used to absorb carbon, were harvested in a big way for farming to feed the growing population. We have destroyed forests and trees to get wood, minerals, land, and build buildings. Today deforestation has taken tall on the amount of trees to absorb the amount of carbon dioxide produced in the environment. Therefore estimating carbon footprint and becoming carbon neutral has become even more important today
