Why the vitality of the River Thames is so important to LondonThe Environment Agency and Thames Water Utilities use two vessels - The Thames Bubbler and The Thames Vitality - to inject oxygen bubbles into the river when levels fall too low; this has been a huge success and the river is now one of the cleanest metropolitan rivers in the world. However, it may look dirty because it is tidal and the pull on the riverbed mixes all the sediment with the water, stirring all the minerals and nutrients up for birds and such like to take advantage of.
