Question

carbondioxide is help the nature.How ?

Answer 1

Carbondioxide is indeed an essential gas in the atmosphere. Acting like a green house gas, it holds the heat inside the atmosphere, preventing the Earth from freezing. Also, it is highly essential for plants, as they need carbondioxide to photosynthesize.

However, too much of carbon dioxide, as it is today, may cause global warming, as it doesn't let heat escape.
