Activity

David Suzuki's Nature Challenge:
For the activity I read about dish on dishsoap.  In the 60s and 70s laundry detergent was a great way to make clothes white but a horrible thing for our lakes and rivers.  For the lakes and rivers the detergent which has phosphate in it turned them green. There than was a limit on how much phosphate concentrations could be in the laundry detergents. Canada was one of the first countries to ban phosphate in laundry detergent, just last year they banned it from being used in dishwasher soup. 
I think this is a good idea, because it is helping out the environment and clearing out of water systems.  It would have been better if they had figured this in the 60s and 70s, but hopefully now things will get better, and we wont have so much phosphate in our water systems.
