La voie de la prudence

Lucas and his aunt Renee spend the afternoon together and go for a walk in the park. Lucas goes to play ball with Victor while Renee rests on a bench. The boys throw the ball back and forth, not caring about the flowers they step on, the branches they hit, the birds they disturb, or a family of ducks they separate. Célestin asks the…

Lucas's class goes to the mountains. The children hope to see the pair of wolves that live there, except for Huan who is very afraid. Emma admits she is afraid of bats; Lucas is afraid of sharks. As for Victor, he admits he doesn't like owls that come out at night screaming. Célestin reassures everyone by explaining the role…

In an old photo album, Lucas discovers that his mother's grandmother used coal to heat the stove. Nowadays, there is almost no coal left and gas is mostly used. Lucas' mother heats the water without putting a lid on the pot. Célestin explains to him that putting a lid on the pot reduces the amount of energy used.

Lucas garde le hamster de Thomas. Quand Célestin découvre la petite bête, il voit qu'elle n'a plus rien à boire. Vite, il avertit Lucas! Cependant, nourrir un animal ne suffit pas, il faut jouer avec lui et entretenir sa cage. Quel travail! Surtout que Woofy a aussi envie que sa niche soit propre.

Aerosols, excessive traffic and even farting cows! All these gases damage the ozone layer that protects the Earth. Lucas is well aware of this. How can he convince his mom and dad, who use insecticides and their car for every trip? Célestin will help Lucas to make himself heard.

Lucas is walking around town. He is holding Woofy on a leash as it relieves itself on the sidewalk. Lucas only wants to get away as quickly as possible, ignoring the poop his dog has made on the sidewalk. Célestin calls him to order. Lucas becomes aware of his responsibilities towards his animal and picks up Woofy's poop with the…

Lucas's class goes on a trip to the sea. The children admire specimens of aquatic fauna that have come to swim at the surface. After lunch, Huan, stuck with his plastic bag, listens to Brice who suggests that he throw it into the sea. Furious, Célestin recovers the bag. He explains that it could be swallowed by a sea turtle or…

Emma, Thomas and Lucas take a break from their bike ride. Emma notices that some horses in a nearby meadow have knocked over the water trough. She wants to alert the owners, but Lucas prefers to continue the ride. Célestin intervenes and explains to Lucas that Emma is right. Like humans, animals need fresh water.

It´s raining. Lucas is sad. He hates the rain. His soccer game has been cancelled. Célestin explains that, in certain countries, rain would be considered a blessing. The children are going to learn about the issues of drought and desertification.

Mom asks Thomas and Lucas to tidy up. With his method of putting everything in the same garbage can, Lucas is suddenly interrupted by Célestin. Célestin shows him the importance of sorting waste because it will then be recycled to make new objects.

On the way to the mountain, Dad remembers passing by as a child. It was beautiful then, there were so many more trees! Célestin explains to Lucas that pollution, caused by trucks, suffocates vegetation. He goes on to talk about acid rain, deforestation and natural disasters.

On his way home from school in the middle of winter, Lucas sees a bird fall at his feet in the snow. He picks it up in his mittens, rushes home and asks Célestin for advice. Célestin suggests putting the bird in a cardboard box near a heat source. He explains that winter is a very difficult time of year for the birds, as they can no…

To get to the waterfall faster, Lucas, Victor and Huan are willing to follow an unmarked path. Célestin shows them the dangers and Emma gets angry: crushing young shoots is not right. After some reluctance, Lucas and Victor soften to the idea because of a rabbit that comes to nibble on the shoots where they were headed.

Lucas and his mother are getting ready to go to the movies. Lucas's mom is looking for her car keys. Lucas is worried about how long it will take them to park the car and suggests that they walk there. Célestin advises him to give his mother convincing arguments. She knows that the city is polluted, but does she know that this…

Lucas doesn't like winter because it's cold, gray and you can't play outside. So he decides to recreate summer in his room by turning up the heat, taking off his sweater and socks. However, Célestin disagrees: it's wasting energy for nothing! We need to save on heating.
