How non-sexual nudity benefits society and the planet
Even a simple T-shirt has a carbon footprint. Consider what goes into it:
Some number of square feet of cotton must be planted, watered and grown to obtain the raw materials. That means food crops cannot be grown and watered on that same piece of land. But every year we are losing crop land east of the Rockies because of flooding, tornadoes, and hurricanes. And every year more crop land is left fallow to the west of the Rockies due to severe drought. Rising sea levels aren't going to help with that either. But while crop land may be shrinking, the world population continues to grow. Someday not growing cotton in order to grow food may become a necessary choice.
Cotton requires massive amounts of fertilizer and pesticide some of which runs off into the local waterways polluting streams, rivers, lakes, and oceans.
Machinery that runs on fossil fuel is used to harvest, de-seed, bail, then transport that cotton to a factory.
More machinery is then used to comb the cotton and spin it into thread. The thread is then either woven or knitted into cloth.
The fabric is probably dyed one or more colors and the excess dye will probably run off into the local waterways polluting streams, rivers, lakes, and oceans.
At possibly another factory the cloth is cut and sewn into a T-shirt. It is then packed with cardboard and plastic and shipped to a warehouse or store.
Finally either you or a delivery driver takes it the final miles to your house.
Every step of this process contributes something harmful to or detracts in some way from the environment. And this is true for every piece of clothing you own. Whether it is made in China or right next door to your house it still cannot help having some impact on our environment.
We live in a society that expects everyone to be dressed in some way all day every day, with only a little time out for showering or bathing. Because of this, the carbon footprint for that T-shirt continues to be added to every time you wear it and then have to wash it, using water, electricity and possibly gas to dry it. Because of this process that T-shirt will one day wear out, be thrown out, and need to be replaced. And when you throw it out, it goes into a landfill which also impacts the environment. Even if you donate it to a thrift store and someone else also gets use of it for a while, sooner or later it still ends up in a landfill.
I live is a small city/large town of some 2,000 inhabitants. If each of us threw out only one pound of clothing per year, that is still one ton of clothing just from my little burg. With the US population at about 330 million people that is 156 thousand tons of clothing per year. But who throws out just one pound of clothes per year? A T-shirt weighs just half a pound but a pair of jeans is two and a half pounds. Think about how many outfits you replace every year. Even if you aren't a “fashionista” you cannot help having an impact on the environment just from wearing clothes.
But our society demands our wearing of clothing, and punishes us if we chose not to. So lets just start at home, where you get to set the rules. What if one day a week you didn't wear a shirt? That would mean that in one year every shirt you owned would last 52 days longer than before. That is a 14% increase in the life of your shirts.
But why stop a just a T-shirt? What if one day a week you wore no clothing at all for 24 hours. You could do all your house cleaning and laundry in the nude. If your back yard is secluded enough you could even do gardening or work on construction projects in the nude. You can cook in the nude (maybe with the help of an apron) and even sleep in the nude. And if you aren't doing anything strenuous and don't work up a sweat, maybe you can even skip showering for a day, especially if you live in a drought area. Now you have a 14% increase in the life of all your clothing, and a 14% reduction in what you are sending to the landfill each year. That may not be very much if just you do it, but if everyone in America did it that is over 22 thousand tons a year (if everyone only threw out one pound) not going into a landfill.
But you say one full day of nudity just isn't practical since you still have to go shopping or to church? Then how about every evening when you get home from work you divest of your work togs and don't put anything on until you are ready to go out the door the next morning? Even if you stay dressed to socialize a couple nights a week, you will still either extend the life of your clothes or have a bunch of items in your wardrobe that very rarely get used so they don't need to be washed or replaced very often.
On hot summer evenings when you get off work, your clothing really isn't helping you much. With clothing on you feel the need to crank up the A/C in order to cool off. But maybe instead you try getting nude and just turning on a fan. You will find that your body can accommodate to any temperature better when you aren't lying to it. If you are wearing a short sleeve shirt and shorts then your bodies central core is reporting a temperature over ten degrees warmer than your arms and legs are reporting. Your body is unsure how to adjust. With nothing on, all parts of your body are reporting the same temperature and it can more easily adjust. On a hot day sitting nude in the shade of a tree, umbrella or EZ-up with a gentle breeze blowing can be as comfortable as sitting fully dressed indoors with the A/C on. Maybe even more comfortable. Of course when the temperature is in the high 90's or triple digits that may not work. But if you can skip the A/C and just use a fan you can save some power for those in hotter areas and possibly help avoid brown-outs and black-outs.
Okay, that's great for summer, but what about the rest of the year? I heat my house to 65 degrees and can stay comfortably nude year round. At first it may feel cool to you and if you are just sitting may even feel cold. (I have heard that 60 degrees is officially freezing in California.) But your body will quickly adjust to it and in the process use some extra calories so that you can hypothetically loose weight while just sitting reading or watching TV. Summer mornings at my house are around 60 degrees and 90% humidity. I find I can comfortably go out in the nude to let the chickens out and play with the dog while enjoying my first cup of coffee in my back yard. This is even true when it is overcast or foggy, not just when the sun shines.
When the sun is shining and/or you are keeping active it is possible to feel comfortable at even much colder temperatures. For example I have shoveled snow wearing nothing but shoes and not frozen off any vital appendages. There is a YouTube video of a group in France that goes cross country skiing on sunny days. Those people remain nude in freezing or near-freezing temperatures for many hours. Finns and Russians like to go from a very hot sauna into a freezing lake or river as an integral part of the true sauna experience. If the people who used to live at Tierra-del-Fuego could survive nude even when it was snowing, then you and I can tough it up and live nude whenever the temperature is between 60 and 90 degrees. You would be amazed at how well your own naked body can adapt to temperature extremes if you only give it the chance.
