If we could protect the environment in a glass dome it would be easier, but as this is not possible, man needs to act quickly for the sake of his well-being. How to lower the level of carbon dioxide (CO2) in the atmosphere if every day we insist on increasing it? In recent years campaigns carried out with the purpose of warning have produced unsatisfactory results, the rates continue to increase alarmingly.
We present here proposals to reduce the amount of CO2 based on studies already carried out.
Iron Fertilization
It is known that algae present at the bottom of the oceans absorb large amounts of CO2 of the atmosphere, the attempt is then based on the increase of this underwater population, but how? Fertilizing the seabed with Iron would increase the proportion of phytoplankton (algae), and so the vast oceans would be partners in combating pollution.
Sulfur in the stratosphere
Nature does have its contributions to the increase in carbon dioxide, it is clear that the effects are a consequence of human action. The Sun, for example, through its rays contributes to global warming. One idea to solve this problem is based on the reflection of sunlight.
Generous amounts of Sulfur would be spread into the stratosphere to induce the formation of sulfur dioxide. This compound would have the ability to reflect the sun's incident rays, deviating their course and preventing them from reaching Earth. If a portion of sunlight were prevented from reaching the Earth's surface, it would be enough to reduce global warming caused by the greenhouse effect.
carbon storage
This is perhaps the most successful alternative to reduce CO2 atmospheric. Large underground tubes would be used to store the released carbon. It would be a kind of storage of pollutants, these could remain in reservoirs for centuries.
The proposal is under debate, presidents are studying it to solve the environmental problem, but there are obstacles such as high value for assembling the reservoirs. It would be advisable to put this idea into practice as soon as possible, as there is a race against time.
How to act in your own home in favor of the environment? Replace your incandescent (common) light bulbs with fluorescent ones. The common light emits carbon dioxide.
