Peat Moss: An Environmentally Poor Choice for Gardeners

For many years, gardeners have been incorporating peat moss into their beds. It fluffs up the soil, helps to retain moisture and adds organic matter. So what is the problem with it? The environmental impact — the peat that we use has been decimating the beds that it comes from.

Environmental Impact of Peat Mining

Peat moss is mostly the decomposed remains of sphagnum moss. Peat bogs, where this moss is located, are part of Nature's water purifiers. They filter approximately 10% of our planetary drinking water. Potable water is quickly becoming a vanishing resource and we need to protect any and all of it that we can. Wetlands like these bogs are also currently the most highly threatened ecosystems on Earth. To rebuild them, some estimate that it would take at least 10,000 years.

Peat bogs are also considered “Earth coolers.” This is because they actually absorb carbon dioxide. When they are mined, this carbon goes back into the atmosphere. Certainly, our planet is now at a point where it can use all of the cooling that it can get. Record temperatures continue upward at a pace thought impossible a few short decades ago. Some believe that the peat bogs store 10% of all of the fixed carbon on the Earth.

The slow natural pace of decay in these bogs makes them a valuable resource for historical activity. Wooden artifacts used by our ancient ancestors have been retrieved from them, as well as some of their bones. They also provide a great deal of flora and fauna specific to their ecosystems. Nesting spots and migratory resting places for birds are an additional benefit.
