| Underwater farm | ||
| We grow vegetables on land and in space.How about underwater？Look at Nemo's garden in Italy.It's the world's first underwater green house.The garden is made up of six to nine big plastic bubbles*.They stay about 4.5 to 11 meters under the sea.Each can hold 2000 litre of air.Scientists grow over 100 different kinds of vegetables there，including tomatoes and beans. | ||
| How to grow vegetables underwater | ||
| ①Water the vegetables Sunlight goes through the water and warms the wet air in each bubble.Salt goes out.Fresh water is left and waters the plants. |
②Watch the vegetables There are sensors* in the bubble to check conditions for the growth of plants.  |
③Pick the vegetables People swim inside the bubble.They put plants in clean plastic bags and bring them on land.  |
| Did you know？Underwater vegetables are richer in nutrition* than those grown on land.They may help to solve future food problems in places without enough fresh water and land. | ||
