Ozone Depleting Substances (ODS) are chemicals that deplete the ozone layer in Earth’s atmosphere. The ozone layer is important because it helps protect us from the sun’s harmful UV radiation. When the ozone layer is depleted, we are at increased risk of developing skin cancer and other health problems.
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.
