4 Things You Didn't Know About Environmentally Friendly Cities

Cities tend to get a bad reputation when it comes to the discussion of environmental problems. But really, there are many advantages to larger cities. That is why many researchers are advocating for the development of strategic, dense cities as a way to minimize negative environmental impacts of inevitable population increase.

1. Cities Have Higher Energy Efficiency

The household energy consumption in cities is much lower than that of surrounding suburbs. This is partly due to lifestyle and housing differences. Much of the city population lives in apartments where heating and air conditioning is much more efficient. Suburban households have a much higher surface area to volume ratio than apartments which provides more area for heat or air conditioning to escape. It is estimated that cities are about 25% more efficient than their suburbs.

2. Carbon Dioxide Emissions Per Person Are Lower In Large Cities Than In Suburbs

According to a UC Berkeley study, suburbs account for about 50% of all US household carbon dioxide emissions. Typically, as population density increases, emissions also increase, but at a certain threshold of about 3,000 people per square mile, the trend shifts and emissions per person is actually lower. This difference is mostly due to lifestyle differences in transportation between cities and suburbs. City dwellers tend to rely much more on public transportation systems and walking while in suburbs, people tend to rely on gas-guzzling vehicles.

3. City Dwellers Can Enjoy Local, Environmentally Friendly Food

There is a lot of research and development going on regarding city self-reliance in food production. A study in Cleveland ,Ohio suggested that much of the city's poultry and produce needs could be met by utilizing empty space such as rooftops and vacant lots to build greenhouses resulting in much lower transportation costs and environmental externalities.

4. Cities That Are Built-Up Are More Sustainable Than Those That Are Built-Out

New York city is a built up city, where population is much denser per square foot of land. Washington, D.C., on the other hand, is built out, having a much lower population density. This results in less public transportation use and fewer pedestrians than in built-up cities where more stores, restaurants, and workplaces are all within a few blocks from each other. It is for this reason, that many environmentalists, scientists, and city planners will advocate for the construction of strategic city nodes of denser population rather than urban sprawl.

I've been super busy lately with school work, studying, etc. Besides the fact that I do nothing but AP chemistry and AP economics, I constantly think of stupid questions that are almost impossible to answer. So, maybe you could answer them for me, and if not then we can both wonder what the answers to these 15 questions could be.

To My Loving Boyfriend,

  • Thank you for all that you do for me
  • Thank you for working through disagreements with me
  • Thank you for always supporting me
  • I appreciate you more than words can express
  • You have helped me grow and become a better person
  • I can't wait to see where life takes us next
  • I promise to cherish every moment with you
  • Thank you for being my best friend and confidante
  • I love you and everything you do

To start off, here's something I don't say nearly enough: thank you. Thank you, thank you, thank you from the bottom of my heart. You do so much for me that I can't even put into words how much I appreciate everything you do - and have done - for me over the course of our relationship so far. While every couple has their fair share of tiffs and disagreements, thank you for getting through all of them with me and making us a better couple at the other end. With any argument, we don't just throw in the towel and say we're done, but we work towards a solution that puts us in a greater place each day. Thank you for always working with me and never giving up on us.
