why do we use greenhouse gases?

Answer 1

For the most part we don't USE them - they are unwanted and unwelcome by-products of processes which we use.

For example, the best-known greenhouse gases are carbon dioxide, CO2 and carbon dioxide, CO. Although CO2 does have some uses (eg. in fire extinguishers and carbonated drinks), the main source of CO2 (and CO) is through burning fossil fuels such as coal and petrol to get energy. We don't burn fossil fuels in order to obtain CO2 and CO and we have relatively little use for them when we do produce them.

This is why an increasing amount of thought is going into developing energy sources which do not produce CO2 and CO, such as solar power, burning hydrogen, wind power and even nuclear power (despite the other risks involved in nuclear energy).

Other greenhouse gases include such chemicals as the refrigerants used in refrigerators and freezers which are being phased out and replaced by non-greenhouse alternatives.

Answer 2

To live. Every breath you take produces carbon dioxide, a greenhouse gas. And we don't "use" carbon dioxide in cars or in our bodies, we use oxygen and carbon; the carbon dioxide is a waste product unavoidable produced by the process.

Answer 3

we use carbon based fuels. they generate energy and also free carbon after their combustion. these are greenhouses gases.

Answer 4

in refrigerators we use cfcs. combustion, burning fossil fuels all play a vital role in greehouse effect, sea level rise etc.

Answer 5

Yes you eat plants and plants require carbondioxide.

Answer 6

Please read into this before asking such a question, theres planty of material out there and you just made yourself look a fool.
