After being hung up overnight in a breezy location, shirts worn once (even in the tropics!) smell quite fresh enough to wear again.
Washing and drying clothes. Washing and drying clothing are common activities that can use a lot of energy - if we aren't careful. But there are a lot of things, most importantly washing in cold water and line drying, which are not only greener, but will make your clothes last longer (as long as you don't leave them outside too long, to fade).

Why does it matter? - Energy usage: We need to use less energy with efficient washers and cold water (unless there is abundant solar hot water), and use renewable energy where possible.

Water usage: The more water we use, the harder it is to process the waste water, and the more strain we place on the water supply.

Water pollution: Minimize the use of detergent. Consider these words about the chemicals you use. Once people appreciate that they make other things dirty when they make their clothes clean, they think differently about what they're doing.

Sun Frost energy efficient shower

Conventional showers minimize thermal comfort, maximize energy use and water consumption, and exacerbating moisture problems... A solution?

Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, and/or stimulate growth. Historically, people secured food through two methods: hunting and gathering, and agriculture.

Agriculture is the cultivation of animals, plants, fungi and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture (e.g. permaculture or organic agriculture).

Sustainable agriculture is the practice of farming using principles of ecology, the study of relationships between organisms and their environment. It has been defined as "an integrated system of plant and animal production practices having a site-specific application that will last over the long term: satisfy human food and fiber needs; make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls; sustain the economic viability of farm operations; and enhance the quality of life for farmers and society as a whole.”
