Activity 2.2.1 My Water Usage

1. Total Household Water Use My Utility Bill: $50 Rate: $0.005 per gallon Total Gallons per Month: 500.005=10,000 gallons per month\frac{50}{0.005} = 10,000 {gallons per month}0.00550​=10,000gallons per month 2. Per Person Monthly Water Use Household Size: 4 people (Me + 3 roommates) Gallons per Person per Month: 10,0004=2,500  gallons per person per month\frac{10,000}{4} = 2,500 {gallons per person per month}410,000​=2,500gallons per person per month 3. Per Person Daily Water Use Average Days in a Month: 30 days Gallons per Person per Day: 2,50030=83.33 gallons per person per day\frac{2,500}{30} = 83.33 \, \text{gallons per person per day}302,500​=83.33gallons per person per day Final Breakdown: Total Household Monthly Usage: 10,000 gallons Per Person Monthly Usage: 2,500 gallons Per Person Daily Usage: 83.33 gallons 2. Online Water Usage Calculators Calculator 1: Hunter Water Calculator URL:https://waterusage.hunterwater.com.au/ Results: The calculator estimated that my household uses 117 kiloliters per year. Converting this to gallons: 117 kL = 30,908 gallons/year Dividing by 365 days: 30,908365=85 gallons per person per day\frac{30,908}{365} = 85 \, \text{gallons per person per day}36530,908​=85gallons per person per day So, this calculator estimates that each person in my household uses 85 gallons of water per day. Calculator 2: Southwest Florida Water Management District URL:https://www.swfwmd.state.fl.us/ Southwest Florida Water Management District Calculator Results: This calculator estimated that my household uses 56 gallons per day. Dividing by 4 people: \frac{56}{4} = 14 ,{gallons per person per day} ] So, this calculator estimates that each person in my household uses 14 gallons of water per day. 3.Data Summary Name of Water Calculator with my per person usage my Utility Bill (83.33 gallons/day per person Hunter Water Hunter Water Calculator 85 gallons/day per person Southwest Florida Water Management SWFWMD Calculator 14 gallons/day per person 4. Summary of Results I discovered some intriguing discrepancies between the estimations from the internet calculators and my actual water usage after doing this exercise. My household uses 83.33 gallons per person per day, which is more over the 80–100 gallons per person per day norm in the United States, according to my actual energy bill. The figures from the online calculators, however, caught me off guard. My real water usage was almost exactly the same as the Hunter Water Calculator's estimate of 85 gallons per person per day. Since this calculator is situated in Australia, it was comforting to know that the figures I computed matched the projections from a broader global viewpoint. The Southwest Florida Water Management District Calculator, however, provided a far lower estimate, recommending just 14 gallons per person per day. This is much lower than both my bill and the other calculator's estimate, which raises questions about the assumptions it makes. Perhaps this calculator is more suited to regions with stricter water conservation practices or different water usage habits. These calculators and my actual bill provide useful insights into the variation in water use across different households and regions. I now have a clearer understanding of how my household’s water usage compares to typical numbers, and I can work toward being more conscious of water conservation in the future.

Activity 2.2- hydrosphere: Mendenhall Glacier in Alaska

Activity 2.2 – Hydrosphere:  Mendenhall Glacier in Alaska Original Photo 2007   (notice the two people walking in the snow 2007)   Second Photo (2015)   Google Earth View (Google Maps, 2025)   Mendenhall Glacier in Alaska, between 2007 and 2015 According to Mutiti et al. (2018), glaciers are an essential component of the  cryosphere , the frozen water part of the Earth system. Problem Over the past century, Mendenhall Glacier, near Juneau, in south east Alaska, has been significantly retreating. In addition to changing the local environment, this retreat acts as a clear sign of larger climate shifts. Comprehending the magnitude and consequences of this glacial recession is essential to understanding how climate change affects cryospheric habitats. Explanation The distance of Mendenhall Glacier from the Juneau Icefield to Mendenhall Lake is roughly 13.6 miles. The Tlingit names Sitaantaagu ("the Glacier Behind the Town") and "the Glacier Behind the Little La...

Activity 4.1 – US Environmental History and Major Regulations.

In the United States throughout history, the environmental thought has shifted from viewing nature as a resource to be conquered and consumed to slowly realizing nature is something we need to respect and preserve. Theis & Tomkin (2018) and Russell & Fairfax (2014), help explain the evolution of environmental regulation and activism. When America first came to be, the settlers were focused on survival and Westward expansion, so nature was often seen as an obstacle. back then, nature seemed limitless. This era was shaped by the idea of “manifest destiny” which encourage expansion for economic gains (Thesis and Tonkin, 2018) By the late 19th century, the effects of unchecked industrialization became hard to ignore as pollution increased alongside water, contamination and deforestation. Muir advocated for preserving nature for its intrinsic value. (Russel and Fairfax 2014) he helped lay the groundwork for the US forest service and national Park service. A key cultural turning po...

Activity 3.3.3- My Plastic Use

Image
Sarah Dudas’s TED Talk, Microplastics Are Everywhere, opened my eyes to the overwhelming impact plastic pollution has on our environment and health. She mentions that in just 65 years, we have produced an estimated 8,300 million metric tons of plastic, yet only 9% has been recycled so the rest ends up in landfills, oceans, and ultimately, our bodies!! Microplastics are tiny plastic particles that never fully decompose, making them a major environmental and health concern. Microplastics are plastic particles that are less than 5mm in size, about as small as a grain of rice. They come in two forms, the first is called Primary microplastics are intentionally manufactured to be small, such as microbeads in cosmetics or fibers from synthetic clothing (Dudas, 2018). Secondary microplastics are a result from the breakdown of larger plastics due to exposure to sunlight, ocean waves, or friction over time (Plastic Soup Foundation, 2019).According to Dr. Erik van Sebille in “Charting the Garbag...
