I think throwing rubbish carelessly in the school river is an impolite act. The school has provided rubbish bin so that students throw rubbish in the rubbish bin, not in the river. This behavior must be followed up. Students who throw rubbish in the river will be fined or punished. So that the river is clean.
Yes, I agree, throwing rubbish carelessly in rivers can pollute the river
