Most plants get their nutrients from the soil. Good soil ensures that plants will grow to be productive and healthy. However, what happens when a plant actually absorbs something that could be harmful?

Some plants called hyperaccumulators simply store it. Hyperaccumulators grow in soils with high amounts of minerals or metals. They do this to defend themselves. Absorbing heavy metals makes the plants toxic to animals that might want to eat them.

Because these plants absorb harmful materials, these plants can be used to clean soil that has been polluted. Once they are planted, they slowly remove heavy metals from the soil. When the plants are harvested, the pollution is removed too. The harvested plants can then be burned, which leaves behind all the metals to be disposed of safely.

What's more, this technique isn't just helpful for controlling pollution. It can be used to mine useful metals, too.
