Carbon Sequestration using trees

Carbon dioxide is a potent greenhouse gas and a major contributor to climate change. Carbon Sequestrating indicate storing carbon in trees which are then turned into Organic Carbon through photosynthesis. This carbon is also stored in plant tissues. Thus furniture made from wood store carbon for a long time.
There are three types of Sequestration,
1. Biological Sequestration
2. Geological Sequestration
3. Ocean Sequestration

Carbon intake has been estimated and below are some quantitative data which can give a clear idea of how effective this can be.
25 year old deciduous tree – sequesters 2.52 lbs of CO2 annually
120 year old deciduous tree – sequesters 5.58 lbs of CO2 annually

25 year old evergreen tree – sequesters 14 lbs CO2 annually
120 year old evergreen tree – sequesters 11.7 lbs CO2 annually
(Figures generated by Tufts (University) Climate Initiative)

Some people believe planting trees just for the purpose of Sequestration could reduce the amount of CO2 in the atmosphere. But an article published in Duke University says, the Carbon Sequ. can cause water and nutrient depletion and increased soil salinity and acidity as side effects over decades. Read more about this.

But that doesnt mean we should stop planting trees. Planting trees as much as we can will help us reduce Carbon levels and delay the changes in Climate if not change it back to before...
