Earth Day, which takes place this month, raises awareness about our environment and how we can protect it.
We were joined today by environmentalist Alexandra Cousteau, granddaughter of the famous marine conservationist Jacques Cousteau. She spoke to us about the problem of overfishing and the importance of protecting the world's oceans. She also talked about how many of the ecosystems she has seen over the years have disappeared, and what we can do to help.
Alexandra will be speaking at the Bord Gais Energy Theatre, Dublin on 23 April to mark Earth Day. For more information, and to buy tickets, see bordgaisenergytheatre.ie.
