CHALLENGE QUESTION #6
Since our water pipes are made out of lead, when water stays in the pipe for a long period of time, the water collects lead. The water in the water pipes emptys out in rivers, oceans, and lakes. Fish live in bodies of water, and may get the lead-poisoning. Bald-eagles eat fish, and may get the lead-poisoning from the fish. It works as a food chain-if a bird ate a fish with lead-poisoning, the bird would get it. And then if a fox ate the bird, the fox would get the lead from the bird.
We can help prevent lead-poisoning by starting to build our water-pipes out of something else.
