Water bottles thrown on side of road

I live on a farm in Limpopo 28 km NW of Bela Bela. I often take a walk to the nearest shop which is 7km away as we do not have a car. Yesterday when on this walk I came across about 50 water bottles thrown on the side of the road by pupils or teachers from Laerskool Lynwood. I know it was them because the label on the bottle clearly stated the name of the school. This area has plenty of wild animals moving around at night and should they decide to try and eat or open one of these they may die or be injured. I feel that it totally irresponsible of the pupils and teachers of the school to do this type of thing or allow it to be done. Teachers in SA are forever crying for more money but they can't even control this type of thing. do they deserve to earn more money, I don't think so. Should anybody from the school wish to contact me, my number is ***.
