How does photosynthesis reduce carbon levels?
Photosynthesis reduces atmospheric carbon dioxide by using it as a reactant in a chemical reaction to create stored energy in autotrophic organisms. This is part of the reason environmental activists are trying to prevent forests being cut down - the forests can help mitigate some of the effects of increased atmospheric carbon dioxide and put a slightly brake on global warming.
What might decrease global atmospheric carbon dioxide?
There is no known way that humans can economically remove carbon dioxide from the atmosphere; all we can really do is reduce our emissions of carbon dioxide and slow down the rate at which atmospheric carbon dioxide levels are increasing. The surface waters of the ocean do absorb some carbon dioxide from the atmosphere as atmospheric carbon dioxide level increase, but there is little interchange betwen the warm upper ocean and the deep layers. However over a period of several thousand years, there is sufficient interchange to absorb large volumes of carbon dioxide, allowing the atmospheric concentration to return more or less to normal. Afforestation. Planting trees will remove carbon dioxide from the atmosphere.
Do forests help reduce global warming and help us fight floods?
Yes, forests remove carbon dioxide, a greenhouse gas, form the atmosphere, release the oxygen, and store the carbon for hundreds of years.Forests also stabilise the ground, preventing erosion, subsidence and topsoil runoff.
Cement work might reduce carbon dioxide why?
The cement work cannot reduce carbon dioxide. In fact, the cement work increases carbon dioxide because carbon dioxide is emitted during the production of cement.
How can we reduce your carbon footprint?
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.

Could artificial photosynthesis be used to reduce atmospheric carbon dioxide?

What organism are scientists using to eat carbon dioxide?
To reduce the amount of carbon dioxide in the atmosphere, scientists are planting more green plants e.g. forests. Green plants require carbon dioxide for photosynthesis.

Does cutting down forests limit the amount of carbon that is removed from the atmosphere?
Yes, cutting down forests (deforestation) means the trees can no longer remove carbon dioxide from the atmosphere. To combat this we have to replant the forests (reforestation) to reduce levels of greenhouse gases.
Is it true that increased levels of atmospheric carbon dioxide are largely due to the increased amount of aerobic respiration by plants and animals?
No. This is part of the carbon cycle, which is a closed system and does not increase or reduce the atmospheric concentration of carbon dioxide. The only way to increase the level of atmospheric carbon dioxide is to bring carbon from outside that system. Volcanic eruptions can add a relatively small amount, but the main source of new carbon is from burning fossil fuels, such as coal, oil and natural gas.
Why is atmospheric carbon dioxide being measured?
Carbon dioxide is causing global warming and climate change. Countries are trying to reduce their emissions of this greenhouse gas. We measure CO2 levels to see if our preventative measures are having any effect.
Why are many governments trying to reduce the amount of carbon dioxide produced by burning fossil fuels?
Many governments, particularly in the European Union, are trying to reduce the amount of carbon dioxide produced by burning fossil fuels in order to slow global warming and cliimate change. Carbon dioxide is a greenhouse gas, and increases in atmospheric greenhouse gases contribute to rapid increases in average global temperatures.
Why is afforestation important?
Afforestation is important because it tries to balance the deforestation that has already taken place around the world. Trees are planted where the land is barren so that forests are created. Growing vegetation like forests is the only thing we have that will remove carbon dioxide from the atmosphere, so forests reduce the speed of global warming.
Do forests help reduce global warming and help us fight floods?
Yes, forests remove carbon dioxide, a greenhouse gas, form the atmosphere, release the oxygen, and store the carbon for hundreds of years.Forests also stabilise the ground, preventing erosion, subsidence and topsoil runoff.
Does deforestation help to reduce global warming?
Deforestation reduces the ability of vegetation to sequester (remove from the atmosphere) CO2. Also the initial clearing of vegetation can release large amounts of CO2. Predominantly though, the burning of fossil fuels is responsible for global warming.
What do you think our authorities should do to reduce global warming?
Make laws phasing out fossil fuel power generation to be replaced by renewable energy.Make laws establishing great forests to remove carbon dioxide from the atmosphere.
