We hear the words 'sustainable' and 'sustainability' almost every day. But what does it mean exactly? Is it about people and culture, our environment, or jobs and money? Is it about cities or the country? Is it about you and me or is it something for other people to worry about?
Sustainability is about all of these things and more.
Sustainability could be defined as an ability or capacity of something to be maintained or to sustain itself. It’s about taking what we need to live now, without jeopardizing the potential for people in the future to meet their needs (“What”).
If an activity is said to be sustainable, it ...view middle of the document...
S. average in carbon emissions. Our finding just go to show that it is important for everyone to know what their footprint is so that they may make the changes that are much needed.
Our solid waste generation is something that not many people pay attention to. All they know is that they must remember to take the trash bin to the curb on the given day and the trash man takes it away. But it is what is done with it after it’s taken away that matters. Not everyone realizes that our landfills are full and soon we will run out of places to take our trash. When our class was asked to bring in 24 hours’ worth of our trash, we found that as a class we produced 540.22 grams of paper, 415.82 grams of plastic, 188.82 grams of metal, 495.6 grams of glass, 55.85 grams of food scraps, and 17.47 grams of “other” trash. These numbers were based on trash that had not been recycled. We weighed our trash again after recycling and found that we only produced 22.24 grams of paper and 93.85 grams of plastic, this change was incredible. If more people just tried recycling for one week and realized just how big of a change it really makes, they would be more likely to stick with it.
A person’s choice of food is usually whatever they can find in the grocery store that is closest to their houses. Unfortunately there is not much more thought put in to it than that. When conducting a lab to become aware of the impact of transportation on the true cost of food we calculated the number of food miles associated with a recipe (based on location where the ingredients were grown and raised). The complexities of our food system and its impact on the environment are...
