Linkages between scientists, managers and politician are important if we like to reduce pollution load in to the environment!

This is to ensure human and environmental health
Water quality is one of the criteria for ecosystem health not just measurement for drinking water.
Water quality is usually associated with excessive of nutrients into the water body, which can lead to eutrophication and later creating algal blooms and depletion of oxygen concentrations which threatens many animal and plant species.
These will cause ecological imbalance, water shortage and climate change.
Close interaction, cooperation and collaboration between scientists, managers and politician will help to solve this common water quality problems and environmental health.
Three most important for ensuring human and environmental health:
1. Emerging research on complex environmental interactions: Ecology
2. Improving integration between public health and environmental and/or ecological sciences.
3. Promotion of ecosystem approach.

All these ideas only can be perfectly done if biologist and ecologist are involve. So far leaders, managers and politician cannot see this or understand the important of scientists or ecologist involvement. What they see only superficial involvement therefore they only solving superficial or surface problems just painting the old house.
