The water that we drink is from rain. However, we cannot drink it directly. We need the purifier to filter out and then can get the clean water. It is not difficult to find various water purifiers for family use. What if there is natural machine to recover the contaminated ones to clean, how good it is? I would like to introduce the South American plant that to purify soil.

Scientists from NL and Brazil discover the plant to use purify the contaminated soil. It is important point that domestic plant is preferred because the invasive species could be harmful. The plants found, Gomphrena claussenii are able to grow on soil polluted with zin and camium and their stem and leaves enable to take up heavy metal. Interestingly, they are not poisoned themselves by toxic

As I can see along the beach where I volunteered, human activities make the soil contaminated. In particular, Cadmium is detrimental to animals as well as humans. The scientists reported through experiments that these plants can resist against heavy metals and has not suffered from contaminated soil. Once they are removed, the zinc and cadmium are also removed with them as well.

The scientists expect that Gomphrena claussenii will bring a safe soil to human within 5 years. This plant is the first plant from South American Plant, which can clean the soil with the most eco-friendly method. The scientists look forward to further research to understand their mechanism.

The best way to protect the environment is absolutely not to damage our nature. However, if we find the sustainable way to solve the problems that already exist, it will be the good option to step forward to preserve our nature. I hope that these plants could be found more than before to protect all.
