Ce n'est pas très grand, vous n'allez pas vous perdre...
Did you know that only 10 percent of the energy used by a typical washing machine powers the motor? About 90 percent of the energy is used to heat the water, and most clothes will come clean in cold water. So switch your washing machine's temperature setting. For heavily soiled clothing, change it from hot to warm, but otherwise try to wash and rinse most of your clothing in cold water.
Did you know that it takes 26 bottles of water to produce the plastic container for a one-liter bottle of water, and that doing so pollutes 25 liters of groundwater? Don’t leave a trail of plastic water bottles in your wake! Stop buying bottled water. Use reusable water bottles instead made from materials like stainless steel or aluminum that are not likely to degrade over time. If you choose a plastic water bottle, check the number on the bottom first: Plastics numbered 3, 6 and 7 could pose a health threat to you, so look for plastics numbered 1, 2, 4 or 5.
