Our life on Earth depends on Carbon dioxide or CO2
Carbon dioxide or CO2 is one of the basic ingredients of the Earth's atmosphere and without it the life on our planet wouldn't exist at first place.
- Although the water vapour is the main greenhouse gas in the atmosphere largely responsible for retaining our sun's
radiated energy that riches the Earth, the CO2 is the second most significant greenhouse gas, and without it the planet would turn into a giant deserted snow ball as it happened in the
past, several times during Ice Ages.
- Plants remove carbon dioxide from the atmosphere as they grow, by the process known as photosynthesis, and without CO2 there would be no plants.
Similarly the growth of algae also depends on the CO2.
The problem right now is that the concentration of atmospheric carbon dioxide has increased by about 35% since the beginning of the
age of industrialization, tipping over the Earth's thermal balance, and causing climate change and global warming.
That is because we are burning various fossil fuels that essentially locked away the CO2 from millions of years ago.
In a natural process known as carbon cycle, the Photosynthesis is the stage where carbon is stored chemically in the form of carbohydrates later to be
released trough rotting.
If we replace the fossil fuel with the biofuel, the carbon cycle would remain sustainable and carbon neutral,
but somewhat speeded up compared to the process that occurs naturally (rotting rather then burning).
