Everyone thinks that every individual can't do anything about it, but we can control it by doing different things in everyday life like planting trees, as it is well known that vegetation is a good carbon absorber. And try recycling, turning off unused lights, walking or biking instead of driving everywhere, or using public transportation, and supporting clean energy like solar and wind power. The most important thing is to educate the people around us because otherwise they don't even know what is happening around us and how it will affect our earth. All nations must also unite because every country that pumps carbon into the atmosphere as said above: one carbon cycle, one part is broken, the whole cycle has dramatic effects on them. So as all nations need to help reduce carbon, it will be helpful because everyone knows about carbon and its effects on the atmosphere as it acts as a greenhouse gas and changes the chemistry of the ocean. Iron fertilization is another possible solution where phytoplankton will convert dissolved carbon dioxide in the ocean into carbohydrates and oxygen
