What do people usually put in their living rooms？Perhaps you will think of something such as a TV，a coffee table or a sofa．But French designers Mathieu Lehanneur and Anthony van den Bossche didn’t think that was enough．They wanted to add something new in people’s living rooms．So they created a do-it-yourself ecosystem（生态系统） named“Local River”．The system lets its owner grow fish and plants inside tanks （缸） in their livingrooms．
In the DIY fish and gardening ecosystem，the plants on top of the tan k feed on the waste of the fish below．It makes the water clean sothe fish can go on living．In this w ay，the fish and plants in the“Local River”can keep the balanced environment，and onlyneed a little help from the owner．The system is also called“fridge-aquarium（冰箱水族馆）”by some peoplebecause owners can use the fish and plants as food．That is to say，owners areable t o grow fish and plants within the“Local River“before eating them．Almost any plant can grow on top of the tanks and mostfreshwater fish are able to live in the tanks below．
The“Local River”ecosystem from Paris comes in small and large models．It is a relaxing thing to have in your home．
