According to the World Health Organization, air pollution is the largest environmental risk, causing seven million premature deaths.

One way to combat air pollutants is to plant trees. However, that's not always an option in urban areas where the air quality is even worse. The WHO reported that more than 80 percent of people live in urban areas where the air quality levels exceed limits. Even worse, 98 percent of cities in middle- and low-income countries are exposed to levels that exceed the limits.

In an attempt to combat this issue, the German-based environmental group, Green City Solutions, created CityTree — the mobile moss display that removes air pollutants and monitors air quality levels.

The moss culture isn't actually a tree, but it provides the air quality benefit of up to 275 trees. They are also very easy to maintain and are very practical for a city center. It has benches attached to it and has room for companies to advertise on it.

They cost about $25,000 to install and have popped up in a few European cities. The company also plans to unveil a plan to bring CityTrees to lower income countries such as India, according to a report by CNN.

Polluted air has been linked to health issues such as cardiovascular diseases and cancer, the WHO reported.

CityTree has not made its way to the United States yet.
