Plenum spaces provide two problems if there is ever a fire. First, by necessity plenum spaces are loaded with fresh oxygen. A small, smoldering fire can really take off if it breaks into the plenum space. The second issue is that the air in the plenum space is forced throughout the whole building.
An adult could survive 2 to 3 days without food as long as they have water. You must get some water into him at the very least! With chameleons, they are rather picky about how they eat and drink.ame with food. Once he sees the crickets hopping around and climbing on the branches, that's when he'll get excited and start hunting. Chameleons are very shy at first, so once you offer food and water, I suggest you step away and watch him from around a corner.
The question of how long you can go without food depends on a lot of factors. Will and determination definitely play a part. Political prisoners on hunger strikes and fasting religious leaders have been known to go for weeks at a time without any food. Gandhi fasted for 21 days while in his 70s. People lost in the wild have also survived for long periods of time without eating. Medically speaking, most doctors agree that healthy humans can go up to eight weeks without food as long as they have water. People have gone longer and been fine, and people have starved to death in less time. Being strong and in good physical shape can help you survive longer, but so does having extra body fat.
