Where does the food you eat come from, a local farm or a far away land? In the United States, the average food item travels 2,500–4,000 kilometers (1,550-2,500 miles) (Worldwatch Institute, Watching What We Eat). The farther food travels before it reaches your plate, the less money the rural farmer retains. Multinational corporations that haul, package, and process the food collect a larger portion of the profit.

The farther food travels, the more energy it consumes for pesticides, preservatives, ripening, packaging, processing, transportation, and sales. Eating local food results in a healthier diet, more equitable profit distribution, less energy consumption, and less environmental pollution.

Cars not only guzzle the world's dwindling supply of fossil fuels, but the burning of those fuels contributes to urban smog, acid rain, and other air quality problems. Cars produce large volumes of carbon dioxide and other greenhouse gases that contribute to climate change. The average car produces about 2.4 kilograms (5 pounds) of CO2 for every liter of gasoline‚ or three to four times its own weight in CO2 every year (Natural Resources Canada). This means more air pollution, more extreme weather and storms, more water contamination, and more diseases.

Public transit, cycling, or walking are simple ways to reduce energy consumption, improve air quality, and lead a healthier lifestyle. If you normally drive to work, take the transit once a week for a refreshing change.

North Americans consume 30 percent of the world's energy — an amount similar to that consumed collectively by all developing countries, holding more than 80 percent of the world's population. While we may flick on the light switch without a second thought, two billion people in the world lack access to electricity or other modern energy supplies (People and the Planet, Energy: Supply and Demand).

While it may be impossible for North Americans to forego the luxuries of electricity, heat, stoves, dishwashers, and microwaves, we can still reduce our energy consumption through efficiency. Europeans have done it — although they lead a similar lifestyle to that of North Americans, people in the United States and Canada consume 2.4 times as much energy at home as those in Western Europe.

Home appliances are the world's fastest-growing energy consumers after automobiles, accounting for 30 percent of industrial countries' electricity consumption. The good news is that energy-efficient lighting and appliances have become common in the North American market. Making your home energy efficient is an easy and effective way to reduce energy consumption without sacrificing convenience (Worldwatch Institute, Making Better Energy Choices).

Vegetables capture energy for growth directly from a renewable source — the sun, while meat production in industrial countries requires a high input of non-renewable fossil fuel energy. When farmers raise animals on pastures, they require little grain, consume little energy, and their manure becomes valuable agricultural fertilizer. Today, in most industrial nations, rather than being pasture-fed, corporations raise animals in factory farms that consume huge quantities of grain, water, hormones, and electricity and produce tons of toxic wastes.

Producing one calorie of beef or poultry requires 11–17 calories of animal feed (Worldwatch Institute, Watching What We Eat). Producing 8 ounces of beef requires 25,000 liters of water (People and the Planet, Deadly Impact of Growing Demand for Meat). This means that a diet high in grain-fed meat requires two to four times more land than a vegetarian diet. Health is another consideration — the crowded conditions of factory farms, along with an absence of waste recycling, make livestock easy targets for disease.

The Prophet allowed us to eat meat and, like all other foods, it is one of Allah's favors that He permits us to enjoy. However, we need to apply the principle of moderation, a key aspect of the Prophet's lifestyle, in our diet. Eating more vegetables, without abandoning meat, can make a significant difference in the amount of natural resources each of us consumes. Next time you bite into that steak, think of the energy that went into producing it.

Canadians generate approximately 1.7 kg (3.75 pounds) of waste per person, per day (Environment Canada, An Environmental Citizen). When we use recycled materials along with recycling and composting our household waste, we significantly reduce our energy consumption and waste production.

Producing aluminum from recycled material, for example, requires 95 percent less energy than manufacturing it from raw materials (Worldwatch Institute, Making Better Energy Choices). Keep in mind that having a recycling box or a compost bin does not justify greater consumption and waste. Reducing consumption is still the best way to reduce our impact on the environment.

The ecological footprint is a tool that assesses the environmental impact of an individual, a region or an activity. Your ecological footprint indicates the amount of biologically productive land area required to support your lifestyle based on the amount of resources you use and the amount of wastes you produce.

Calculations show that the planet has available 1.9 hectares (4.7 acres) of biologically productive land per person to supply resources and absorb wastes, yet the average person on Earth already uses 2.3 (6.7 acres) hectares worth. These "ecological footprints" range from 9.7 hectares (24 acres) claimed by the average American to 0.47 hectares (1 acre) used by the average Mozambican (Worldwatch Institute, State of Consumption Today). Calculate your ecological footprint by taking the Earth Day Footprint Quiz and discover your impact on the planet. The results may shock you!
