For individuals who live and work in large busy cities, living green can be a bit more difficult. While the amount of driving and car emissions is cut down, other footprints show up. One may wonder if the quick and easy street vendor with it's CO2 generator is really the best choice. There are a couple of things to consider. One is the generator vs. the power plant. Generators are generally dirtier and may release more greenhouse gases, but restaurants use energy 24/7. Secondly, the trucks must move to and from the central location to unload and dump waste water and oil, etc. Restaurants advantage on this point might be outweighed by the fact that they use energy 24/7. Trucks although they may put out more emissions, are in use for less time and generally stay in one place. This means that the emissions from driving the truck around are not a huge factor. They also reduce the number of emissions from customers. If a street vendor serves 100+ customers a day that would otherwise drive to a restaurant, then that may give them an edge. The green conscience individual must always remember that packing one's own lunch from home is the greenest choice. Eating leftovers from the previous night's meal reduces waste and extra energy use. Also using one's own utensils that can be washed and used again is always better than throwing plastic ones away. Eating a green lunch can have many options. Which one will you choose?
