Children, we are going to make a excursion about the enviroment and the pollution
Children, rubish and plastic pollute the seas, the ocean, rivers, etc.For this reason, you should not throw away the rubish.
Now we are going to clean this dirty beach. When we finish, we are going to take a pedal boat.
That's a huge puddle of petroleum.When the ship sails, they release oil or gasoline.That is very bad for the fish and birds that feed on them.We are in a pedal boat that doesn't pollutes the environment.
Children, I'm wearing now a snorkel tube, that's because we are going to go diving with a submarine.
