Water is Life | Mathematics of Sustainability

Water. Water is an essential part of human life on Earth. We as humans are made of water, use water everyday, and need water to survive. It helps regulate all of our functioning parts of our complex bodies and ensures benefits of living a healthy life. Just as humans are extremely dependent on water, so are many other species such as the group of livestock. One animal in particular is cows, which are heavily connected to greenhouse gasses and Co2 emissions. Depending on the temperature that a cow is living in, the weight of the cow, and whether it is producing milk or not, correlates to the amount of water it needs daily. It has been estimated that for cows, “Daily water intake may vary from 3 to 30 gallons per day depending on age, body size (weight), stage of production, and the environment (mainly air temperature).” With an increase in temperature or lactating cows, this requires more clean water for them. But to put the stat of 3 to 30 gallons in perspective, every human is advised to drink 8 cups of water per day, which is half a gallon of water. So although cows are much larger than humans, their daily water intake is extremely large and crucial for them.

Water is an essential to everyday life but there is a ton of water being wasted annually in the United States. An article published by the Washington Post states, “The incredibly stupid way that Americans waste 1 trillion gallons of water each year.” 1 Trillion gallons of water is another worldly large number and the ways depicted that Americans waste water are water leakage, hoses, and irrigation systems: all are not needed waste methods of water. One way to prevent the wasting of water would be to be more aware of how you are potentially wasting water. This can be from fixing leaks immediately, shutting off your sprinkler system when not needed, and using less water related activities such as dishwashing and laundry. If there was to be less water wasted, the number conducted through the Washington Post of 1 trillion gallons, could be minimized by millions and millions. Not to mention saving water waste, but this can save thousands of dollars spent by homes and businesses.

One method of intaking water that is very popular is through bottled water. It is so popular because it is pre bottled, convenient, and can be disposed of. Although it is not economically and environmentally friendly, Americans live a fast paced life and want the fastest way to intake water. To put water bottle usage in perspective on Union College’s campus, let’s first say there are 2,200 undergraduate students. I’d say about half of the students here use plastic water bottles daily, so 1,100. If every student is drinking about 3 bottles a day, that’s 3,300 approximately, plastic water bottles. To calculate the amount of oil used to produce and ship the water to Union, I estimated around 15,000 gallons of fuel to get the water from Western states all the way to Union College.

I find it interesting how large the spectrum is for daily water intake for cows. I was not expecting it to be between 3 and 30 gallons.
