Ozone, a component of the earth's atmosphere is having 0.00006 percent of the dry atmosphere and it is mostly located in the stratosphere. Its location in the second layer of the atmosphere is meant to screen out one of the electromagnetic waves known as ultraviolet ray which is a short wave radiation heating up the earth's surface. The data were collected through literature search, hence, it is theoretical in nature. It is meant to conceptualize ozone, ozone depletion; identify causes of ozone depletion and to proffer what could be the proper control measures. The ineffectiveness of ozone shield to perform the primary function of protecting both biotic and abiotic components of the natural ecosystem from the scorching effects of the ultraviolet ray due to human activities such as urbanization, industrialization that cause pollution implies the destruction of valuable components of the earth's total ecological systems and the manifestation of its consequential outcomes. It is revealed that ozone depletion could trigger rising earth's temperature, reduction in crops' yields, disruption of marine food chain, inhibition of photosynthesis, skin cancer, blindness, genetic changes, and human immune systems' impairment among others. To curb this bane from its multiplier effects, it is suggested that the use of ozone friendly materials should be embraced in the production of products by industries. People should be educated on how best to interact with their biophysical environment to curb excessive pollution of man's environment.
