We require healthy water and air, and so do we require healthy soil. It makes water clean and serves as a growing medium, It provides a living space for billions of organisms. And it also provides us with food. Therefore, we should do something to protect the soil.
One of the easiest ways we can support the soil is by wasting less food. All the food that ends up in our shopping bags requires land, water and energy to produce. By throwing away less, we will prevent materials in soil from being wasted.
By eating different types of foods, we can help create demands for different farming products, which is better for soil. Food diversity can improve soil quality. In general, eating a diverse (多样的) diet is better for our health too.

When we walk through any garden store, there are many products for our gardens. No matter which product we end up selecting, the most important step before using it is to read the instructions, Misuse can cause problems.
If we are looking to fertilize (施肥) our garden，we need to know what materials are already in the soil before adding more. Or, we might just need to add one specific material, and not others. Local university laboratories can help provide information on testing soil. It’s usually a matter of digging up soil from a few areas of the yard and sending it in to the lab!

B. Eat a diverse diet.
C. Perform soil tests.
