The impact of chlorofluorocarbons (CFCs) on atmospheric ozone is starkly illustrated in Bill Bryson's "A Short History of Nearly Everything." A mere kilogram of CFCs possesses the capacity to destroy an astounding 70,000 kilograms of ozone. This highlights the devastating effects of human-made chemicals on the environment and emphasizes the fragile nature of the ozone layer, which is crucial for protecting life on Earth from harmful ultraviolet radiation.

This dramatic statistic serves as a wake-up call regarding the consequences of industrial activities. The significant ozone depletion caused by CFCs underscores the need for strict regulations and alternatives to protect our atmosphere. Bryson's work sheds light on the interconnectedness of human actions and ecological health, urging readers to understand the importance of sustainable practices to preserve the environment for future generations.
