Anesthesia and Global Warming ?

When you think of anesthesia you probably think of surgeries or dental operations. But anesthesia doesn't only help you to go to sleep during surgeries or dental operations it also helps global warming. When I stumbled upon this information during research I was very shocked. I never knew getting a tooth extraction or having a surgery could harm our planet even more.
 However, anesthetic gases have been found in the atmosphere. The gases are greenhouse gases which means they trap heat in the atmosphere. They even trap more heat per pound emitted than carbon dioxide. For example, the gas desflurane traps 2,500 kilograms for each kilogram.
 Though, research confirms that anesthetic gases only contribute a small amount to climate change or global warming. But that doesn't mean that we shouldn't do an effort to reduce the amount of anesthetics we use or try to find an alternative. It is quite alarming that the gases could even be measured at all in the atmosphere.
