Composting is an aerobic method of decomposing organic solid wastes. It can therefore be used to recycle organic material. The process involves decomposing organic material into a humus-like material, known as compost, which is a good fertilizer for plants.
Renewable energy is a vital part of the effort to create a sustainable future. It doesn’t produce pollution or greenhouse gases, and it doesn’t use up finite resources like fossil fuels. Renewable energy comes from sources that are renewable, meaning they can be replaced or replenished. The most common renewable energy sources are solar, wind and hydro power.
