The river is the habitat and residence of various animals and plants. Humans also make the river a part of them and use the river for survival. Many benefits can be taken, therefore we must maintain the river so as not to switch functions and lose the good benefits obtained from the river. Maintaining the quality of springs, maintaining ecosystems in rivers, not disposing of garbage, is a way we can maintain the river. In addition, there are many activities that we can do such as planting trees on the banks, fish restocking, biotilik, and socializing and educating the community about the importance of rivers for the next generations. Help us to realize a sustainable Brantas river.
