We can reduce BOD and pollution with better wastewater treatment plants, like the ones China is building, and using eco-friendly farming techniques to prevent runoff."
"The main sources of pollution here are industrial waste, agricultural runoff, and littering. These aren’t just problems for animals—people who drink or fish from this water are also affected."
"Good question! Banning single-use plastics and organizing cleanups are great ways to keep trash out of the water."

Yikes! How can we fix it?"
What about the trash?
