Today, we are living on a planet that is frequently changing. Some of these changes are caused by natural processes, but many believe these changes in climate are a direct result of human activity. Luckily, we have the power to make small changes to reduce the impact on our planet. Every day, we throw away garbage that releases harmful toxins into the air, land, and water. One way you can prevent harmful pollutants is by composting. Composting is the process by which organic materials, such as fruit, vegetables, eggshells, tea, and many other foods, are broken down, recycled, and used as a fertilizer. As a fertilizer, compost provides rich nutrients to the soil. It is very beneficial to your gardens, as it nourishes your plants and flowers and helps them bloom more frequently. It is very easy to start composting. All you need is a wooden or plastic compost bin and the organic matter to put in it! Composting helps the environment because it reduces the amount of waste in landfills, reduces pollution, and prevents soil erosion. Take a stand, and help make the planet we live on a healthier place.
