In recent years, food safety has become important to many people. Some families have stopped eating out. They have started cooking at home.

However, they still worry about the ingredients (原料) they use. So, is there any way we can eat safely?

There just may be. People in Brazil have a wonderful way that they would like to show us.

     Sao Paulo is the largest city in Brazil. Growing vegetables by themselves has become popular. Most people in the city live in apartments, so they don’t have a garden. But if you make good use of the space on your balcony (阳台), it’s enough to grow vegetables for a family of three. These “urban (城市的) farmers” all say the vegetables they grow taste good. What’s more, they are safe and fresh.

Growing vegetables by ourselves has many good sides. First, these vegetables won’t be polluted by pesticides (杀虫剂). Second, because they are fresher, they are often good for health. The vegetables also make the indoor air cleaner. Last but not least, the relationship between family members may become better as they work together.

Now, you have learned about all of these good sides of growing vegetables by yourself. Do you want to try it? I believe it will be easy if one of your family members has a green thumb. But if not, look for some advice. Here is a useful book: The Edible Balcony.
