Atmospheric pollution continues to rise as the planet can no longer filter all the pollutants in the atmosphere.
Now that we are dependent on these two sources of energy, pollution cannot decrease because the demand for energy is constantly increasing and there are more people on the planet every day who need it.
How long will it take for humans to stop using these polluting energy sources and switch to green energy that is accessible to everyone? Several years, even decades, or perhaps centuries. Furthermore, will the major countries and others have the capacity to make these changes quickly while also cleaning up?
How many decades can the atmosphere continue to absorb pollution before permanent climate disruption caused by human activities occurs?
With the increase in the global population, we will need more places to house people and more food. Thus, more humans, less vegetation, and more pollution.
We can see the harmful effects of these pollutant concentrations in cities, manifested as smog. The planet continues to poison itself a little more each day with this growing population.
These pollutants are produced by industrialization, transportation, agriculture, and electrical energy. Interfering with these sectors would lead to severe economic problems, ultimately slowing down investments in environmental cleanup. Thus, it will take even more time to achieve potential cleaning of the atmosphere we breathe or the oceans, which are the cradle of terrestrial life.
As long as humans remain dependent on fossil fuels, the atmosphere will continue to thicken over time with increasing pollution. This pollution will cause global temperatures to rise due to the greenhouse effect and accelerate the melting of the polar ice caps.
Will we be able to live on a planet where it is perpetually hot? What will the temperature be at the equator in 50 years? Are we capable of decontaminating the atmosphere?
