Best Answer

This is because the carbon dioxide has spoil therefore it dies and disappear

Carbon Dioxide isn't exactly removed from the air. Animals, like humans, breathe in Oxegyn and breathe out Carbon Dioxide. Plants on the other hand, like trees, take in carbon dioxide, and emmit oxegyn, creating and endless cycle.

There are currently at least 12 technologies available for this purpose, with different capabilities and prices, according to reference studies that the Intergovernmental Panel on Climate Change may rely on in its forthcoming Monday report, which will be devoted to available solutions for the climate change front.

vital energy

Bioenergy for carbon dioxide absorption and sequestration is based on growing trees that absorb this gas during its growth, then burning it to generate energy (biomass) and burying the carbon dioxide derived from this process in neglected mines, for example. However, the results of this technology, whose usefulness is still preliminary, must be crystallized on the ground.

One of the few projects in the world commercially developed for this purpose in Britain was withdrawn from the Standard & Poor's Clean Energy Index for not meeting sustainability criteria.

Planting trees

Another solution offered is restoring forests and planting trees to absorb and sequester carbon dioxide through photosynthesis.

Many companies, including those producing fossil energy, rely heavily on these cultivated areas to "compensate" for their emissions.

However, the area required to significantly reduce carbon dioxide levels by planting trees, which may reach twice the size of India, negatively affects other priorities, such as agriculture dedicated to providing food and preserving biodiversity.

New forests may be vulnerable to fires that multiply as warming increases, which could release all the carbon dioxide trapped in the air.

Direct absorption

One of the newer technologies of greatest interest is direct atmospheric carbon capture and sequestration.

Chemical processes help extract carbon and convert it into a solid or landfill. However, since carbon dioxide is widespread in the atmosphere, this technology consumes a lot of energy and costs dearly.

And even if these innovative technologies receive the attention and financing of dignitaries such as Elon Musk, they remain very expensive and questionable regarding the speed of their development.

rocks and oceans

One technique involves cutting mineral-rich rock that absorbs carbon dioxide, crushing it and spreading it in soil or water. The goal is to accelerate this path that normally spans tens of thousands of years in nature.

It remains to be seen whether the process can be applied on a sufficiently large scale and at what cost.

The oceans, in turn, absorb more than 30% of global carbon emissions, and scientists are testing ways to enhance these capacities, for example by artificially enhancing marine alkalinity or "fertilizing" the oceans, that is, increasing the density of phytoplankton that sequester organic carbon through photosynthesis.

The implications for ecosystems of these strategies and how this method can be replicated on a larger scale is not yet known.

Why is there is so little carbon dioxide and more oxygen in Earth's atmosphere?

Algae and later plants carried out photosynthesis, which uses sunlight to convert water and carbon dioxide into sugar and oxygen. This process removed carbon dioxide from the air and added oxygen. Additional carbon dioxide was removed and locked away in carbonate rocks such as limestone.

Where plants get carbon dioxide from?

How can carbon dioxide be removed from the air and replaced by oxygen gas in submarine?

They use a 'gas exchange system' - usually chemicals that split the carbon dioxide molecules into atoms of oxygen and carbon. The oxygen is recycled back into the air in the submarine, and the carbon is retained for disposal.

Are bio-fuels good?

Yes because they do not add polluting carbon dioxide to the atmosphere, causing global warming. (They release carbon dioxide that was recently removed from the air, so biofuels are carbon-neutral.)
