Phosphates killing our rivers

From weekly Science Matters column by David Suzuki:

Phosphates are added to cleaning products because they help cut grease and get rid of food particles on dishes. But they also have enormous negative impacts on rivers, streams, and lakes. By fertilizing the waters, phosphates can cause massive algae blooms that starve the water of oxygen and choke aquatic ecosystems, killing fish, amphibians, insects, and plants. Phosphates have been banned from laundry detergents in most places for a number of years now, but consumers have resisted moves to ban them from dish-washing detergents.........We can lead lives that are even more fulfilling on a cleaner planet where more people have access to clean air, water, and food. All it takes is some imagination and some forward thinking. If we really cared about our world and about our children and grandchildren, we would be willing to make some sacrifices to make the world a better, healthier place. But in most cases, the sacrifices are as illusory as some of the benefits we think we are deriving from our rampant consumerism.."

Could we choose to buy our detergents Phosphate free????????????????????????
