Humans are natural explorers. From the beginning of time we have wanted to know what things looked like over the hill and across the ocean. Our legs took us wherever they could, and then humans invented ships and cars, submarines and space shuttles.
 
It is really possible that there is an unexplored environment on planet earth?

That’s what a recent artice is Discovery Magazine claims.

According to scientist Jessica Green, “We live nearly 90 percent of our lives indoors, but we know almost nothing about that environment. We don’t think about the wildlife in the air because we can’t see it. But it’s here.”

Think about it! Your home does not house you and your family alone. There are microorganisms living on the surface of literally everything in your home – from furniture to floors. And there are microorganisms living in the very air “flowing around us and into our eyes, noses, mouths, and lungs Millions of microbes fight for survival.”
 
“Air isn’t empty,” Green continues. Not even close: A cubic meter of indoor air contains up to 10 million cells of bacteria. “Each one of us is shedding microbes from our bodies and resuspending microbes that have settled on the floor, on desks, on trash cans. They’re swirling all around us. We’re constantly walking through a microbial soup.”
