When we're out traveling, unless we're taking our cars or visiting someone who will let you use their car, our modes of transportation become limited. However with new rideshare apps like Uber of Lyft, we can easily summon a stranger in a car to take us wherever we want to go. But is this really the most effective way of travelling when we're away from home? According to wanderu, busses might be the most effective way of travel, with the least amount of CO2 emissions. Busses only give off 0.17 lbs per passenger mile.

I agree with what you are saying, however, in our day in age fossil fuel cars are the main modes of transportation. Transportation only makes about 15% of the world's CO2 emissions. In the case of reducing CO2 emission while helping ourselves too is agriculture. The act of raising and processing livestock into consumable meat is on par with transportation. Agriculture makes about 13.8% of the carbon emissions and meat is the most inefficient use of energy. The process of raising animals takes up an astounding 41% of the United States' land. Less consumption of meat opens up options for reducing obesity, carbon emissions, greenhouse gases, and more land for agriculture. Although I can agree with the taste and look of consuming meat the benefits highly outway the disadvantages. The following articles can back up what I claim and also provides a chart to breakdown the CO2 output categories. https://www.theguardian.com/environment … -emissions
