Happy 40th Anniversary, Earth Day

Happy 40th Earth Day Everyone!

As I’ve written before, on April 22, 1970, I attended one of the first Earth Day celebrations (as did 20 million others that day). The one I went to was held at Santa Monica City College.

In those days, most of us in the environmental movement worried about the population bomb exhausting our resources and causing global famine; and we feared air pollution causing another ice age through global cooling. Obviously, we hadn’t considered the population bomb causing global warming through our exhalations and farts. Little did we know.

I had a copy of The Population Bomb by Paul R. Ehrlich in my back pocket back then, before the world wide web and cell phones. Many doomsayers proclaimed Malthus—an eighteenth century economist who argued that human population growing exponentially would quickly outstrip crop yields which grew arithmetically—was a Pollyanna. Like Malthus, Ehrlich was convinced that the world’s exponential population growth would outstrip the earth’s ability to cope and we’d devour everything on earth like locusts. We needed to curb out population NOW or humankind would implode like the locust. We’d be standing on banana peels over our graves if there were any bananas to be found, the skyrocketing population had already eaten them.

Indeed the world’s population has almost doubled, yet instead of cleaning off every whit of resource and the world being poorer, sicker, and hungrier, we find that since 1970: we are three times richer (in real terms), the percentage of people in abject poverty has dropped by over two-thirds, a greater percentage of people are better fed, the average person in a developing country eats more, the world’s forests cover 99 98% of what they did in 1970, and the known oil reserves have nearly doubled.

Here’s a comparison of where we were in 1970 and where we are today:


Comparison of earth in 1970 with earth 2010

1970 2010 % Change
World population 3,692,492,000 6,816,100,000 84.6%
The percentage of the world population living on less than $1 a day (in PPP-adjusted 2000 dollars) 26.80% 5.40%
Forest on the earth (in billion hectares) 4.03 3.94 -2.2%
Avg Daily Kilo-Calories per person in a developing country 2135 2674 25.2%
Known oil reserves (in billion barrel) 650 1200

The world did not change the way Ehrlich, Malthus, and others thought it would. So the environmental raison d’être has changed. Population still gets flung about but now it’s global warming that’s being shouted by knowledgeable experts. We need to curb our pollution population greenhouse gases NOW or humankind will freeze to death starve to death, well I’m not sure but trust me, the Malthusian prophets of doom will continue to bang their pots and rend their clothing. Things may yet grow worse, as Bullwinkle J. Moose used to say, “This time for sure.”

The world will change over the next 40 years, tell me are you more optimistic or pessimistic about the state of the world’s environment for those years?

Happy Earth Day

On April 22, 1970, I, along with 20 million others that day, attended one of the first Earth Day celebrations (Read the history of Earth Day here, written by the founder, Senator Gaylord Nelson). The one I went to was held at Santa Monica City College (yes, Dustin Hoffman’s and Arnold Schwarzenegger’s alma mater). In those days, most of us in the environmental movement worried about air pollution causing another ice age through global cooling.

I was a nineteen-year-old student attending SMCC, and my main concern was the over-harvesting of trees leading to the permanent loss of forests, especially the deforestation of the Amazon’s rain forest. Deforestation was my reason for entering into the field of forestry.

I transferred after a couple years to Humboldt State University in Arcata, California. I majored in Forest Management. It turns out forests in the United States and other countries (primarily in the OECD) are doing just fine. The information is contained in public records such as:

Forest Resources of the United States, 2002: A Technical Document Supporting the USDA Forest Service 2005 Update of the RPA Assessment by W. Brad Smith, Patrick D. Miles, John S. Vissage, And Scott A. Pugh.

RPA Assessments report on the status and trends of the nation’s renewable resources on all forest and rangelands, as required by the Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974.

So what are the trends and status our nation’s renewable resources?

  • About 33 percent of our nation’s 2.3 billion acres of land area is forest today as compared to about one-half in 1630. Some 300 million acres of forest land have been converted to other uses since 1630, predominantly agricultural uses in the East.
  • Fifty-seven percent of all forest land is privately owned. Private forest land is dominant in the East. Public forest land is dominant in the West.

The graphic shows that for the last 130 years or so the forest area of the United States has remained nearly the same or grown. Only the Pacific Coast has diminished slightly.
