The two zones of the park had very different wildlife.

The word "ozone" has a fascinating origin, stemming from the Greek word "ozein," meaning "to smell." This is quite fitting, as ozone possesses a distinct, pungent odor, often described as similar to chlorine or the fresh scent after a lightning strike. In fact, German chemist Christian Friedrich Schönbein coined the term in 1840 after he successfully isolated this gaseous chemical, recognizing its characteristic aroma. Ozone is a special form of oxygen, made up of three oxygen atoms (O3) rather than the usual two found in the air we breathe.
This unique gas plays a dual role in our world, leading to a common distinction between "good" and "bad" ozone. High in the stratosphere, the "ozone layer" acts as Earth's protective shield, absorbing harmful ultraviolet radiation from the sun, which is essential for life on our planet. However, at ground level, ozone is a harmful air pollutant, formed from reactions involving vehicle exhaust and industrial emissions, contributing to smog. So, while a distant whiff of ozone might signify protection, a strong scent closer to home often signals air quality concerns, a curious linguistic twist for a crucial molecule.
