Our Story

April 22, 1970

The ideas and values that motivate Colcom Foundation’s philanthropy can be traced back to a landmark of modern environmentalism - Earth Day 1970.

April 22, 1970

The First Earth Day

The first Earth Day represented a movement that propelled many cultural, regulatory, and legislative wins for ecosystems in the United States and around the globe. Stricter regulations on polluters, cleaner energy sources, more efficient technologies, and individual commitments to consume less or consume differently have helped many decimated ecosystems recover and have slowed the pace of environmental degradation.

HOWEVER

The environmental movement’s overall effectiveness has been consistently undermined by the failure to address one of the first Earth Day’s primary goals: the stabilization of population size both in the U.S. and globally.

Environmental Gains Are Undermined By Population Growth.

Continued rapid population growth has been a major factor in magnifying the ongoing extinction crisis, climate crisis, habitat destruction, overconsumption, and our generally oversized collective ecological footprint.

The U.S. Cut Per Capita CO2 Emissions By 35%

From 1970 to 2021, the U.S. successfully cut its per capita CO2 emissions from 21.33 metric tons to 14.04, a 35% per capita decrease.

But population growth overwhelmed per capita efficiency gains

Over the same period, though, the U.S. population grew by another 62% from 205 million to 332 million. The environmental gains from the 35% reduction per U.S. resident were overwhelmed by 62% more residents, resulting in a net increase in overall CO2 emissions between 1970 and 2021 of 0.67 billion tons (a 15% increase).

One Step Forward, Two Steps Back

A similar story can be told about urban sprawl, species extinction, nitrogen pollution, habitat destruction, and almost any other key environmental metric one may choose. Human population growth leaves the environmental movement continuously taking one step forward and two steps back.

The U.S. Has Been in Severe Ecological Overshoot Since 1970

Biocapacity utilization data tells an even more dire story as it calculates the total ecological footprint and is a much more holistic and realistic measure of sustainability than CO2 alone.

Definitions

Ecological footprint

“A measure of how much area of biologically productive land and water an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates, using prevailing technology and resource management practices.” See the Global Footprint Network’s Glossary for more definitions: Glossary - Global Footprint Network

Ecological Deficit

“An ecological deficit occurs when the Ecological Footprint of a population exceeds the biocapacity of the area available to that population. A national ecological deficit means that the nation is importing biocapacity through trade, liquidating national ecological assets or emitting carbon dioxide waste into the atmosphere. An ecological reserve exists when the biocapacity of a region exceeds its population's Ecological Footprint.” – Global Footprint Network

The U.S. was consuming 227% of its available biocapacity in 1970. By 2020, that number had increased to roughly 240% despite massive efforts and expenditures to reduce it. Between 1970 and 2020, per capita biocapacity use decreased more than 20%, meaning 100% of the overall increase in biocapacity use (all of which was additional overshoot) was the result of human population growth.

BIOCAPACITY CONSUMPTION

However, the overshoot calculations above assume humans have the right to appropriate all available biocapacity and leave nothing for other species. If we want to set aside 30% of the natural world for other species, as the 30x30 initiative targets, the U.S. was at roughly 341% biocapacity utilization in 2020. If we want to achieve the more ambitious goal of leaving half of nature for other species, the U.S. was at 478% biocapacity utilization in 2020.

How Much of the Natural World Should Humans Leave for Other Species?

The “30 x 30” initiative directs 30% of the United States be left for other species. “Half Earth” proposes half the Earth’s surface area be designated a natural reserve in order to save at least 80% of Earth’s species. But currently, here in the U.S. and around the world, the human population is consuming biocapacity at a pace that will leave virtually nothing for other species.

Business as Usual

Humans consume 100% of nature

30x30

Humans consume 70% of nature

Half-Earth

Humans consume 50% of nature

Total ecological footprint data provides the most comprehensive measure of sustainability but it can be difficult to visualize what these calculations mean for ecosystems in the real world.

Land use data indicates by 2020 the U.S. had paved or built over the equivalent of Montana, West Virginia, and South Carolina combined while 52% of the U.S. land base was consumed by agricultural uses and only 13% enjoyed any level of conservation protections.

Human population pressure and its associated effects have robbed wildlife of its natural habitat. The results are profound. The North American bird population has decreased from ten billion to seven billion in fifty years.

Wildlife populations in general have seen similar declines.

How did we get here?

1970

Where we started

· The first Earth Day celebration identified the need to curb environmental degradation resulting from both per capita consumption and human population growth.

· In 1970, total fertility rate (TFR) in the U.S. was 2.54, resulting in a 1.25% population growth rate.

· 1.25% may seem low, but at that growth rate it would have taken only 57 years for the U.S. population to double from 205 million to 410 million. In other words, in 1970 the U.S. was on track to have 410 million people by 2027.

1972

Total fertility rate stabilizes

· The U.S. achieved the environmental milestone of a total fertility rate (TFR) below 2.1 (replacement level fertility) by empowering women to take control of their reproductive choices.

· A sustained TFR of 2.1 would have resulted in population stabilization over several decades.

· TFR has never gone above 2.1 in the U.S. since 1972.

1990

U.S. population grows by 45 million

· The U.S. population increased by 45 million between 1970 and 1990.

· Immigration became the main driver of U.S. population growth around 1990.

· Roughly 133,000 square miles of land in the U.S. was consumed by human-made structures and surfaces by 1990.

· U.S. biocapacity consumption rose to 237%, up 10 percentage points from 1970.

2000

U.S. population grows by 32 million

· The U.S. population increased by 32 million between 1990 and 2000.

· U.S. biocapacity consumption rose to 267%, up 30 percentage points from 1990.

· Roughly 156,000 square miles of U.S. land was consumed by human-made structures and surfaces by 2000, an increase of 23,000 square miles since 1990.

2020

U.S. population grows by 48 million

· The U.S. population increased by 48 million between 2000 and 2020.

· 1965 - 2020 immigration scenarios between zero and actual levels would have resulted in a 2020 population between 255 million and 330 million.

· 1,300 species were listed as either endangered or threatened in the U.S. under the Endangered Species Act (ESA) by 2020.

· 23 species were proposed for delisting from ESA due to extinction in 2021.

· Over 187,000 square miles of U.S. land was consumed by human-made structures and surfaces by 2020, an increase of 31,000 square miles since 2000.

· North American wildlife populations declined 20% since 1970.

2030 and Beyond

Immigration will determine the future of U.S. population growth.

· 82% of population growth from 2005 to 2050 will be a consequence of immigration alone.

· Immigration is projected to account for 103 million in U.S. population growth by 2065.

· The larger the US population, the less likely the U.S. will meet its Paris Climate goal; the more difficult it will be to conserve native species; the larger America’s total ecological footprint will become.

· U.S. citizens have the right and the responsibility to collectively act to limit our total ecological footprint. The future of biocapacity consumption, urban sprawl, bird population, air pollution, and overall number of threatened, endangered, and extinct species is up to us.

The U.S. Will Add 8.5 LA Metros by 2065

According to Pew Research, the U.S. is projected to add 110 million to its population by 2065, 103 million of which will be from immigration alone. This is the equivalent of adding 8.5 Los Angeles metro areas to the U.S. landscape.
