Hello today in teach we had to find out how they are going to make our rivers in hawke's bay clean and this is what i wright.

The tukituki river is polluted because if there is a river beside the farm and when the cows poop and when it rains the poop gets washed into the river. also when they spread fertiliser and the same thing will happen. If we reduced the amount of phosphorus there would be less algae and slime.

My opinion...
I reckon that if we had less farms around the rivers the rivers would be less piloted.
Instead of using fertilizer they could just use organic fertilizers like soil and compost.
