What is one way humans impact the water cycle?
You should have one of the following:

List one way we can protect our water resources
Answers can vary, but they should address solutions for blocking water flow, pollution, or using too much water.
Solutions for blocking water flow:
- Build fish passages (ways for fish to travel around a dam).
- Protect riverside areas; plan building projects carefully
Solutions for pollution:
- Put trash in bins; clean up litter.
- Never pour chemicals into drains; use safer products when possible.
- Plant greenery to slow runoff and trap dirt (rain gardens, grasses).
Solutions for using too much water:
- Fix leaks; turn off water when not needed.
- Water plants at better times (morning/evening).
- Use water-saving tools (low-flow, efficient sprinklers).
