Answer:
Carlsbad Caverns should be open for tourism.
Step-by-step explanation:
Some of the common reasons why people think Carlsbad Caverns is a bad place to tour are: there are bats in the caves, steep/wet trails, can be claustrophobic, crowded, and radon levels. Let's go over each reason and why they aren't necessarily true.
Bats in the caves. Bats do live in caves systems so it's not unusual to see them there. Some people my have an averse reaction to bats, but by visiting any larger cave, you will run into this same problem.
Steep/wet trails. Caves systems are usually created by dissolution of limestone. This means that rainwater seeps into the limestone (rock) and eats away at is because of the acidity. Like the bat problem, you will often see running water and slippery trails in caves.
Claustrophobic. Caves aren't always claustrophobic, though the trail that leads up to the main attraction may be. Being in tight spaces or surrounded on all sides is something you kind of sign up for by touring a cave system. Nothing about Carlsbad Caverns in particular makes it bad for tourism.
Crowded. Crowding can definitely be an issue when it comes to touring caves on the designated trail. However, deeper caves tend to be warmer than the surface during colder weather. Given this, you could vising Carlsbad Caverns any time of year and have comfortable temperatures. Not only is it warmer because it is underground, but the humidity level is increased due to water presence.
Radon levels. Radon levels can cause lung cancer, but only through long-term exposure. Long-term exposure would be over 5 years. The radon levels in Carlsbad Caverns doesn't qualify because you wouldn't be tourning for long enough for the levels to be detrimental to your health. Basements in homes sometimes have Radon problems and this is solved using a Radon-mitigation system. But this is for a living space, not a national park that people tour occasionally.
