The bottled water industry sold 8.8 billion gallons of water in 2010, generating nearly $11 billion in profits. Yet plastic water bottles create huge environmental problems. The energy required to produce and transport these bottles could fuel an estimated 1.5 million cars for a year, yet approximately 75 percent of water bottles are not recycled – they end up in landfills, litter roadsides, and pollute waterways and oceans. And while public tap water is subject to strict safety regulations, the bottled water industry is not required to report testing results for its products. According to a study, 10 of the most popular brands of bottled water contain a wide range of pollutants, including pharmaceuticals, fertilizer residue, and arsenic.
What you can do:
- Fill up your glasses and reusable water bottles with water from the sink. The United States has more than 160,000 public water systems, and by eliminating bottled water you can help to keep nearly 1 million tons of bottles out of the landfill, as well as save money on water costs.
(5) Turn down the heat
The US Department of Energy estimates that consumers can save up to 15 percent on heating and cooling bills just by adjusting their thermostats. Turning down the heat by 10 to 15 degrees Fahrenheit for eight hours can result in savings of 5–15 percent on your home heating bill.
What you can do:
- Turn down your thermostat when you leave for work or use a programmable thermostat to control your heating settings.
(6) Support food recovery programs
Each year, roughly a third of all food produced for human consumption – approximately 1.3 billion tons – gets lost or wasted, including 34 million tons in the United States, according to the United Nations Food and Agriculture Organization (FAO). Grocery stores, bakeries, and other food providers throw away tons of food daily that is perfectly edible but is cosmetically imperfect or has passed its expiration date. In response, food recovery programs run by homeless shelters or food banks collect this food and use it to provide meals for the hungry, helping to divert food away from landfills and into the bellies of people who need it most.
