Dealing  with water & rivers pollution is something that everyone need to get involved with.. here are few thing you can do as students to help reduce water pollution . First you can create posters to reduce pollution and place it next to each trash bin instead of throwing the rubbish in the rivers we ensure by people to throw in the right place for the right thing, also we could start planting our crops and plants far from the river, that will keep the water clean from any chemicals or fertilizers or dirt's that can be taken by the water if you live by a river , but be careful of what you throw down your sink or toilet, dont throw paints,oil or other forms of litter down the drain, moreover use the water we use wisely by turning off the tap of the water if it is not necessary this helps preventing water shortages and reduce the amount of contaminated water that needs treatment. By these notes, rivers could be a better place for perfect uses like domestic uses :)
