There are a number of reasons. Composting provides a partial solution to an issue of great concern in many communities. All around the country, landfills are filling up, garbage incineration is becoming increasingly unpopular, and other waste disposal options are becoming ever harder to find. Composting provides a way not only of reducing the amount of waste that needs to be disposed of, but also of converting it into a product that is useful for gardening, landscaping, or house plants. By addressing the solid waste issue, composting provides a way of instilling in children a sense of environmental stewardship.
Many educational programs focus on reducing, reusing, and recycling our solid wastes.
Composting fits in with this idea but takes it a step beyond. They learn through direct experience that they personally can make a difference and have a positive effect on the environment. Another reason for composting in schools is that it provides a rich topic for scientific investigation and discovery . Composting is appealing to a wide range of ages. Worm bins are a popular form of composting with young children, who are fascinated with the worms' feeding and reproductive habits.
