These young people want to do their part for the planet. Under the Maestro's supervision, they prepare a butterfly garden after learning that butterflies are an endangered species.

France's Aube department has the highest concentration of wind energy in the country, which makes it the perfect place to experiment with new wind technologies and create a model for all of Europe.

Some people believe that plants contain pollution-reducing properties. However, a study by a group of researchers in Lille debunked that theory.

Could you imagine being told that you're adopted and then being kidnapped immediately after? That's what happens to the little critter in the first part of this "Zooriginaux" episode. It definitely sounds like the grounds for an identity crisis!
