Do We Ignore Tobacco’s Positive Ecological Role Too Long?

Definitely, tobacco is one of the most troubling plants in this planet because of its harmful effects on humans. Therefore, tobacco plantation declines continuously in the world. For such a plant, do we need to eliminate tobacco entirely from the surface of the earth? Perhaps, humans might have ignored the tobacco’s positive role in environment and ecology, especially in the heavily industrialized environments, for too long. Because the human activity generates more and more nitrogen oxides (NOx) in atmosphere, which not only cause imbalance in the global nitrogen cycle but also lead to haze, smog, acid rain, PM2.5, and eventually impact on environment and human health. Unfortunately the current technologies do not provide an efficient way to remove NOx from atmosphere. However, it is only tobacco can remove NOx from atmosphere. Perhaps, we should blame us, humans who use tobacco unwisely, rather than blame tobacco in nature. Anyways, the ability of tobacco to remove NO2 from atmosphere should not be ignored.
