    GIY stands for “grow it yourself” and is about a new fashion for growing your own food. There are a lot of reasons why growing your own food is a good idea. GIY helps reduce carbon dioxide (CO2) emissions (排放物). Food in supermarkets travels a long way and that produces a lot of CO2. If you grow as many vegetables as you can at home, you can help save the earth.

Vegetables you grow are also good for your health because they have more nutrients than supermarket vegetables and they don’t have chemicals.

How much money can you save? First of all, seeds are a lot cheaper than vegetables, and secondly, you can save more by planting the most expensive and the most productive (多产的) vegetables. You can give your vegetables to friends and neighbors. It can make you very popular.

Don’t worry if you don’t have much space. To GIY, you don’t even need a garden. You can use pots on your balconies (阳台). And don’t worry if your space doesn’t get much sun. You can plant vegetables that don’t need a lot of sun to grow.
