The two elements I chose to compare in my graphs were the CO2 emmissions in tonnes compared to the new cases per 100,000 men of lung cancer. There was a very clear trend showing that the more CO2 emmisions, the more cases of lung cancer. In the left, with the lowest lung cancer and CO2 emissions we can see the African nations, and to the right, with the highest CO2 emissions and the newest cases of lung cancer we can see east european nations like Hungary or Croatia. In this graph there are a few countries that do not follow the trend like Qatar or Kuwait, but this is probably due to the small populations of these countries.
It is known that emissions of CO2 are a main cause of lung cancer, as is demonstrated that china is the country with the most deaths caused by lung cancer and also at the same time the country with the highest CO2 emissions. As shown in our graph living in a country with many CO2 emissions is very hurtfull for ones health. Even though the cause of lung cancer is not only affected by CO2, there are other causes like genetic factors, radon gas, asbestos, smoking or second hand smoke.
One of the problems of this graph, is not only that lung cancer can be caused by many factors not involving CO2, but that also that the CO2 emmisions are measure by tonnes per person and instead, it would be easier if they would be measured in a whole country, this way showing the countries with actually the highest CO2 emissions like China or India instead of countries like Qatar, Kuwait, Australia or Canada.
