The pie chart illustrates the main causes of global warming worldwide, while the table compares the percentage of CO₂ emissions from different sources across three continents: Europe, America, and Asia.
Overall, vehicle exhaust fumes are the leading cause of global warming, followed by factory fumes and deforestation. In the table, although each continent has similar main causes, the percentages vary.
According to the pie chart, the percentage of global warming caused by vehicle exhaust fumes, at 34%, which was higher than factory fumes, at 30%. The percentage of deforestation contributes 25% to global warming, while the percentage of overpopulation was the lowest, making up 11%.
In the table, the percentage of CO₂ emissions from vehicles was highest in Europe and America, at 35% and 33% respectively. At the same time, the percentage of CO₂ from deforestation was greatest in America, at 31%, while Europe had only 15% and Asia had the lowest figure, at 9%. Meanwhile, the percentage of CO₂ caused by overpopulation in Asia (31%) was higher than that of Europe and America. In contrast, the percentage of factory emissions remained relatively close across all three regions, ranging from 27% to 33%.
In conclusion, vehicle fumes are the main contributor to global warming globally, but each continent shows different levels of CO₂ emissions depending on the cause.
