In what way does composting contribute to environmental sustainability?

• A. It promotes the use of synthetic fertilizers
• B. It reduces the volume of waste sent to landfills
• C. It increases the need for chemical waste disposal
• D. It hinders the recycling process

Answer: (B)

Composting significantly contributes to environmental sustainability by reducing the volume of waste sent to landfills. When organic materials such as food scraps, yard waste, and biodegradable products are composted, they decompose naturally, returning nutrients to the soil while also keeping these materials out of landfills. This process not only helps to divert significant amounts of waste from landfills, which can lead to reduced methane emissions (a potent greenhouse gas produced from decomposing organic waste in anaerobic conditions) but also enriches the soil, improving its overall health and enhancing its capacity to support plant growth.

Furthermore, by composting, communities can conserve landfill space, which is a critical resource. As landfills reach capacity, new sites must be found or created, often leading to more land use and environmental disruption. Composting, therefore, aids in mitigating these issues while promoting a circular economy where organic waste is reused beneficially rather than disposed of in a harmful manner. This practice aligns with sustainable waste management goals and contributes to healthier ecosystems.
