5 A tiny organism called a tardigrade (“water bear, moss piglet”) can survive for 10 years or more without eating OR drinking!!! (Although they only achieve this feat by going into a state of ‘suspended animation.’) Willow Gabriel and Bob Goldstein, http://tardigrades.bio.unc.edu/ http://tardigrades.bio.unc.edu/ https://www.youtube.com/watch?v=SUC0_HjNFBs See more here: 5 EXTREME SURVIVOR!!!

6 On the other hand, humans can only survive a few days without water… In fact, water is SO IMPORTANT to the proper functioning of our bodies that even after a few hours, you can begin to see signs of DEHYDRATION – or the lack of water! DID YOU KNOW? One of the 1 st early signs of dehydration is…. GRUMPINESS! That’s right, irritability can be a sign of low-level dehydration. Amazingly, scientists estimate that about 75% of Americans are in a near-constant, low-level state of dehydration!!! That ’ s a LOT of grumpy people... 6

Water can contain: Microbes (germs) that can make us sick… Dirt, sediment, algae… Pollutants like metals, minerals, nutrients, and chemicals… That’s where your utilities come in!!
