Our Fragile Earth – Think about it
I have a concern about our short-term thinking. The stock market moves up or down based on the news and/or psychology of the day. Publicly traded companies focus on quarterly results. Politicians focus on elections every two years. As a Homo Sapiens we have only been around for about 200,000 years (or about 6,500 years if you are a Creationist).
Mother Earth has been around for about 4.5 billion years and some form of life has existed for about 3.5 billion years. The Dinosaurs showed up about 250 million years ago and ruled for almost 200 million years. The Egyptians ruled for over 2,700 years and the Roman Empire took over for the next 500.
Our country has existed for less than 250 years and has only been a world leader for about 75 years. In the last 60 years the world population has doubled!
The land that we occupy is only about 1/3 of the surface of the Earth. The earth’s crust (that we depend on for life) is only about 18 miles thick below land. The remainder is mostly ocean that has an average depth of about 2 ½ miles. The crust below it only aveages about 5 miles. Think about these measurements in terms of the size of the earth which has a diameter of 4,000 miles.
What about the atmosphere that we require to breath? Healthy people can survive to 10,000 feet. Above that, most people need oxygen. From 12,00 feet to 50,000 feet oxygen and a pressure suit or a pressurized container is required. Above 50,000 feet a fully sealed suit or a space suit is needed.
To summarize these facts: We live on an extremely thin outer crust of the planet and rely of an extremely thin band of air to stay alive. As a species we have been around for less than .006% of the time since life emerged. Home Sapiens took the first 199,940 years to provide a population of 3.6 biiion and only 60 years to add another 3.6 billion. Do you see a problem here?
