Question

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（设计师）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 living rooms.

In the DIY fish and gardening ecosystem, the plants on top of the tank feed on the waste of the fish below. It makes the water clean so the fish can go on living. In this way, the fish and plants in the “Local River”can keep the balanced environment with a little help from the owner. The system is also called “fridge-aquarium (冰箱水族馆)” by some people because owners can use the fish and plants as food. That is to say, owners are able to grow fish and plants within the "Local River" before eating them. Almost any plant can grow on top of the tanks and most freshwater 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.
