Band 6+: 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.

The pie disgrams illustrate the main causes of worldwde glal warming, while the table compares proportion of cog emiscon from different sources in three continents: Europe, America, and Asia

Overall, vehicle exhaust fumes are the key factors lead to global warming. In the table, the percentage of CO2 emitted by the resources varies in each continents

Regarding the pie chart, the percentage of global warming caused by vehicle exhaust fumes are the highest, at 34%. Followed by factory fumes, which account for 30% and more than deforestation at 25%. The percentage of overpopulation is the lowest, at 11%.

In the table, the percentage of CO2 emissions from vehicles is the highest in Europe at 35%, while America and Asia have the same proportion of 33%. Europe has the greatest percentage of Co2 emissions, at 33%, followed by Asia and Ameria at 27% and 19%, respectively. The amount of CO2 caused by deforestation is the largest in America, at 31%, while Europe has only 15%, and Asia has the lowest figure, at only 9%. Meanwhile, the percentage of CO2 caused by overpopulation in Asia, at 31% is higher than figure of Europe and America at 17%.
