This sounds like a joke, but this new invention does exactly that, merges the two functions of each separate device. At the bottom of the fish tank is an additional tank which contains freshwater fish, with pods for growing vegetables at the top. The neat part is that the plants filter the water which gets to the fish, whilst the fish fertilize the water for the plants. The Locavores appeared in San Francisco in 2005 and define themselves as ‘a group of culinary adventurers who eat foods produced in a radius of 100 miles (160 km) around their city’. By doing so they aim to reduce impact on the environment.
