Those grow around the people. The reality is you’ll be hard pressed to find a community that doesn’t have some sort of danger like this.
I suppose you’re right about that. All I know is I would not live any where near a fertilizer or chemical plant. I would tell my realtor to look in a different location. We used to live near a rendering plant and I can tell you that sometimes the smell was so bad that it wilted the flowers! I’m serious.
