The Importance of Healthy Soil
Farmers began using chemical fertilizers and pesticides around 50 years ago in order to boost crop yields. Over time, insects, weeds and plant diseases have developed resistance to these pesticides, which has prompted the development of stronger pesticides and the need for multiple applications during the growing cycle. Despite the tremendous increase in the use of pesticides since 1950, the percentage of crop volume lost to pests has remained about the same.
A study conducted by the International Food Policy Research Institute shows that 40 percent of the world’s agricultural soil is seriously depleted due to erosion (a result of planting the same crop over and over again), nutrient depletion (due to the use of chemical fertilizers) and salinization (the build-up of salt in the soil due to excessive irrigation).
The good news is that organic farming methods, such as rotating crops, using compost or manure instead of chemical fertilizers, and careful water use can reverse this damage and rebuild healthy soil.
7 Reasons to buy Organic
When it comes to your health—and the planet's—here are the top seven reasons why you might want to purchase organic foods whenever possible:
Thoroughly washing conventional produce and trimming away edible peels will help minimize any chemical residue while still retaining a high level of nutrients. If organic foods don't fit into your budget or lifestyle, try not to worry. Most health authorities report that the health benefits that come from eating fruits and vegetables outweigh the concerns of pesticide use. Whether you select organic or conventionally grown produce, eating five to ten servings of fruits and vegetables each day is still the healthiest way to get the vitamins, minerals and fiber you need as a preventive health measure.
Protect the health of children. Children are exposed to four times the level of pesticides in food than adults. Pesticides affect children more profoundly due to their higher metabolisms and smaller body mass.
Look after your own health. Several pesticides that are banned in the U.S. and Canada are used on foreign crops and shipped here for consumers to buy.
Safeguard the health of farm workers. Studies have shown that conventional farmers have six times the cancer risk of non-farmers. Because fertilizers and chemicals are often distributed by air, farm workers can be exposed to large quantities of chemicals without protection.
Preserve the soil. Over three billion tons of topsoil are lost each year in the United States and Canada due to erosion caused by conventional farming methods.
Protect the water. Pesticides are known to contaminate groundwater, which affects the drinking water supply in most of the United States and Canada. If pesticide-contaminated water reaches lakes, rivers and other bodies of water, it allows the rapid growth of algae and suffocates the natural aquatic plants and animals.
Conserve resources. Conventional farming uses a vast amount of petroleum-based herbicides to kill weeds, while organic farming uses labor-intensive practices such as weeding by hand.
Fight global warming. Petroleum-based fertilizers give plants the nitrogen they need for rapid growth, but these nitrogen compounds can enter the atmosphere and contribute to global warming.
