Gyre: A gyre is any large system of rotating ocean current, particularly those involved with large wind movements.
O-Zone layer: The O-Zone layer is a barrier protecting the Earth from the Sun. As the rays from the Sun are so strong, the O-Zone layer protects us from them. From all our pollution of trucks and cars, we have made a hole in the O-Zone layer. If the hole continues to widen, our world could be under risk.
