Hello! 
The answer is 0%. I have already learned about this! :)
        
                    
             
        
        
        
There are two branches of the autonomic nervous system, namely the sympathetic nervous system and the parasympathetic nervous systems. Both of which regulates bodily functions involuntarily but in different manners. The parasympathetic system is the system primarily activated in "relaxed" states or "rest and digest" states. These include digestion, urination, slowing of heart rate, slowing of respiratory rate, etc. The sympathetic nervous system on the other hand is primarily activated by "flight or flight" response such as rage or fear. These include inhibition of digestion, increase in heart rate and respiratory rate, sweating, etc.
        
             
        
        
        
Region of the World                             Percentage    Value in Metric tons
North America                                          17                  23,332,500
Asia                                                          52                  71,370,000
Africa                                                          3                    4,117,500
Europe                                                     18                  24,705,000
Latin America and the Caribbean              8                  10,980,000
Oceania                                                  <u>   2</u>                <u>    2,745,000</u>
                                                               100                137,250,000
We multiply the 137.25 million metric tons by its percentage to get its equivalent value in metric tons.
Asia uses 71.37 million metric tons. 
In making the bar graph, The vertical line will be the percentage and the horizontal line will be the region. Bars of each region should have different colors for easy identification. Spaces between bars should be present, so that the bar graph will not be confused with the histogram.
