It would be later with the advent of cars and personal purchasing power and the exponential growth of consumerism that the reality would take a prominence as a scientific pursuit. Even in 1960, there was a race to find the evidence and reverse the trend when scientists realize how long the growth of greenhouse gases had existed.
In the early 1960s, C.D. Keeling measured the level of carbon dioxide in the atmosphere: it was rising fast. Researchers began to take an interest, struggling to understand how the level of carbon dioxide had changed in the past, and how the level was influenced by chemical and biological forces. They found that the gas plays a crucial role in climate change, so that the rising level could gravely affect our future.
The pursuits of this alarming reality would be conducted on a short while when it became evident 'The Greenhouse Effect' would override Earth's ability to maintain life 'in the thin blue line.' '
Keeling began the study which would result a decade later in the first "Earth Day" on April 22, 1970. Below is Ron Cobb's Ecology Symbol. And the race to stop deadly trends was launched with full vigor and still hangs in the balance today.
