We have now entered
the USGS laboratory. The scientists here who study phosphates have agreed
to help us learn about phosphates. So far they have told us that phosphates
are not toxic to people or animals unless they are in high levels of
phosphates also phosphates are one cause of pollution in lakes and streams.
When lakes or streams have to many phosphates, it can grow into clogging
the pipes or streams so fish can’t get through. The phosphates
can be from septic tanks, run off from fields, and waste waters. What
really scared us was when Dr. Spongebob told us that to many phosphates
could cause humans in the future to have digestive problems. That all
seemed sooo interesting don’t you agree? |
