10 foods that are bad for the planet

We know what foods are bad for us, and we know that we should eat them in moderation to stay healthy. However, there are also many foods that are bad for the Earth’s health. Check out these 10 foods that are hurting the environment and learn how you can eat a more planet-friendly diet.

healthy eating, healthy planetMeat

According to the Environmental Defense Fund, if every American substituted one meal of chicken with vegetarian food, the carbon dioxide savings would be the same as taking more than half a million cars off U.S. roads. Here are some of the U.N. Food and Agricultural Organization’s findings on meat and the environment:

• 18 percent of greenhouse gas emissions come from livestock — more than from transportation  • 70 percent of previously forested land in the Amazon was cleared to pasture cattle  • The world’s largest source of water pollution is the livestock sector  •  Livestock are responsible for a third of the nitrogen and phosphorus in U.S. freshwater resources  •  Livestock account for about 20% of land animals, and the 30% of Earth’s land they occupy was  once inhabited by wildlife.

Genetically modified foods

As with human health risks, it’s unlikely that all the potential environmental harms of genetically modified foods have been identified, but here are some of the main concerns about GMOs.
• Lower level of biodiversity: By making a crop resistant to a certain pest, the food sources for other animals could be removed. Also, the addition of foreign genes to plants could be toxic and endanger the animals that consume the plant.
• Creation of new diseases: Some GM foods are modified using bacteria and viruses, which means they could adapt and create new diseases.
• Spread of altered genes: Novel genes placed in crops won’t necessarily stay in designated agricultural fields. The genes can easily spread via pollen and share their altered genes with non-genetically modified plants.

Sugar

More than 145 millions tons of sugar are produced in over 100 countries each year, according to the World Wildlife Fund, and production on such a scale takes its toll on the Earth. Sugar may be responsible for more biodiversity loss than any other crop, according to a 2004 WWF “Sugar and the Environment” report, due to its habitat destruction, its intensive use of water and pesticides, and the polluted wastewater discharged during the production process.
Thousands of acres of the Florida Everglades have been compromised after years of sugar cane farming — subtropical forests became lifeless marshland after excessive fertilizer runoff and irrigation drainage. Waters around the Great Barrier Reef are also suffering due to the large quantities of pesticides and sediment from sugar farms.

ANYTHING CONTAINING High-fructose corn syrup

High-fructose corn syrup is one of the most environmentally damaging ingredients for several reasons.  Firstly, corn is grown as a monoculture, meaning the land is used solely for corn and not rotated, which depletes soil nutrients, contributes to erosion and requires more pesticides and fertilizer.  The use of such chemicals contributes to problems like the Gulf of Mexico dead zone, an area of the ocean where nothing can live because the water is starved of oxygen, and atrazine, a common herbicide used on corn crops, has been shown to turn male frogs into hermaphrodites.  Milling and chemically altering corn to produce high-fructose corn syrup is also an energy-intensive practice.

Fast food

Fast food is hurting more than just our health.  A typical fast-food meal often comes with overly packaged food, straws and plasticware, and an assortment of individually wrapped condiments. According to Californians Against Waste, less than 35 % of fast-food waste is diverted from landfills even though most of it is recyclable paper and cardboard.  So it’s no surprise that litter characterization studies have identified fast-food restaurants as the primary source of urban litter.
But it’s not just the packaging that’s a problem.  A recent Hong Kong study found that a fast-food restaurant making four hamburgers emits the same amount of volatile organic compounds as driving a car 1,000 miles!  If you calculate the carbon footprint of a burger, you’re in for a real shock: The greenhouse gas emissions arising each year from the production and consumption of cheeseburgers is roughly the amount emitted by 6.5 million to 19.6 million SUVs.

Processed and packaged food

The majority of the food you’ll find in the grocery store is processed and packaged, which is bad news for the planet.  Processed food contains multiple chemicals and often involves energy-intensive production processes.  Plus, all that packaging typically ends up in a landfill, where plastic poisons the environment and can take thousands of years to break down. In fact, in 2006 the U.S. generated 14 million tons of plastic through packages and containers alone, according to the EPA.  Unfortunately, even those eco-friendly packaged items made from cardboard are coated in a thin layer of plastic. The solution?  Buy local, eat fresh fruits and vegetables, and buy foods like rice, oats and pasta from the bulk bins.

Many non-organic or conventionally grown foods

Organic produce is grown without pesticides, which keeps chemicals from entering the water supply and helps prevent soil erosion. Organic farming also uses fewer resources than traditional farming. According to a study by The Rodale Institute, organic farming practices use 30 percent less energy and water than regular growing. In fact, a study by David Pimentel, a professor at Cornell University’s College of Agriculture and Life Sciences, found that growing organic corn and soybeans produced the same yields as conventional farming and used 33 percent less fuel. However, not all produce needs to be bought organic.

Palm oil (and foods that contain it)

Palm oil is found in an estimated 10% of U.S. groceries — it’s in chips, crackers, candy, margarine, cereals and canned goods.  About 40 millions tons of palm oil, which is considered the cheapest cooking oil in the world, is produced each year, and 85 percent of it comes from Indonesia and Malaysia.  In these countries, 30 square miles of forests are felled daily, and palm oil plantations account for the highest rates of deforestation in the world.  When the rain forests disappear, so does almost all of the wildlife, including bears, orangutans, tigers and other endangered species.

Certain types of seafood

Fisheries analysts at the U.N. Food and Agricultural Organization report that 70 percent of the world’s fisheries are fully or overly exploited, depleted or in a state of collapse.  Fish like bluefin tuna and Atlantic salmon are severely overfished, and environmental groups are working to get them endangered species status. The overfishing of a particular species doesn’t damage that population alone — it can have serious effects further up the food chain and decrease biodiversity. Check out the Environmental Defense Fund’s seafood eco-ratings to determine what fish is safe for both you and our oceans.

White bread

It’s well known that whole grain and wheat breads are more nutritious than white bread, but brown breads are also less harmful to the environment. Wheat flour must be refined and go through a series of alteration processes to make white bread, but whole wheat flour spends less time in production. Any ingredient that requires extensive refining requires more energy and resources and has a greater impact on the planet.
