This topic is all about soil, how it is formed, how it is lost, and how to look after it.
Without soil, nothing would exist. No plants or trees would grow, and we would have nothing to eat. The soil is like the human body. In order to be healthy, it needs food, water, shelter and rest. Plants grow by taking the nutrients and minerals they need from the soil. We get the nutrients and minerals we need from eating those plants. Soil is essential to life, but each year Africa loses thousands of millions of wheelbarrow loads of soil to erosion. Without shelter, harsh sunlight bakes the soil, and torrential rains wash it away. We need to find ways look after it, and fortunately, there are many things people can do to help soil restore and keep its fertility. Even the smallest child can play a part in looking after the crucial resource underneath our feet.
