3. This mass of brown algae, which is 8,000 km long, moves according to ocean currents.

4. Mr. Sauvé points out that these aquatic plants can pose a health hazard. It may “contain sulfur gases which are of greater concern and which may be toxic”.

The professor states that the dangers mainly threaten the people who will be called upon to move this mass and clean the beaches. For tourists, it is more of an inconvenience.

5. “There is supposed to be an excess of fertilizer used in agriculture. If it collects in waterways or the sea, it helps to increase the growth of this algae. What seems exceptional this year is that it happened so early,” says the expert.

6. This algae stays on the surface because of the tiny air bubbles it forms.

7. When they pile up on the beach, they stink because they are rotting.
