Indicators of Ecological Collapse
- Climate change is affecting us now.
The Intergovernmental Panel on Climate Change (IPCC) issued a report that says the effects of climate change are already occurring on all continents and across the oceans. Observed impacts of climate change have already affected agriculture, human health, ecosystems on land and in the oceans, water supplies, and some people’s livelihoods.35
- Climate change will dramatically reduce access to fresh water.
Climate change over the 21st century is projected to reduce renewable surface water and groundwater resources significantly in most dry subtropical regions, intensifying competition for water among sectors. In presently dry regions, drought frequency will likely increase by the end of the 21st century. Climate change is projected to reduce raw water quality and pose risks to drinking water quality even with conventional treatment, due to interacting factors: increased temperature; increased sediment, nutrient, and pollutant loadings from heavy rainfall; increased concentration of pollutants during droughts; and disruption of treatment facilities during floods.
The more warming that occurs in the 21st century, the more people will experience water scarcity and the more people will be affected by major river floods.36
- Coastal and low-lying areas will suffer from rising sea levels.
Due to sea-level rise projected throughout the 21st century and beyond , coastal systems and low-lying areas will increasingly experience adverse impacts such as submergence, coastal flooding, and coastal erosion.36
- Climate change may reduce crop production.
For the major crops (wheat, rice, and maize) in tropical and temperate regions, climate change without adaptation is projected to negatively impact production for local temperature increases of 2°C or more above late - 20th - century levels.36
- Global temperatures are increasing dramatically.
According to the EPA, the Earth’s average surface temperature has increased by about 1.40 F in the last 100 years.1 Climate models predict that the average temperature of the Earth could increase up to 11°F by the year 2100.33
For some perspective, the last ice age occurred at 11°F less than the current global temperature.
- Global carbon dioxide emissions continue to rise.
Global annual carbon dioxide emissions from fossil fuels have risen from ~2,000 teragrams (2 million metric tons) in 1900 to ~32,000 teragrams (32 billion metric tons) in 2010.1
Human activity (especially in industrial economies) releases roughly 7.4 billion tons of carbon dioxide per year into the atmosphere. That’s 20 million tons of carbon dioxide per day, 843,000 tons per hour, 14,000 tons per minute, and 230 tons per second.32
- Atmospheric levels of carbon dioxide continue to rise.
Levels of atmospheric carbon dioxide have increased to 385 parts-per-million by volume (ppm)2, a 100-ppm increase since pre-industrial times.3 It rises by more than 2ppm each year.5 “The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5° to 10° F higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland.”30
A 2008 conference of climate experts reported carbon levels are highly unlikely to be restricted to 650 ppm, or perhaps even 1000 ppm. Such levels would translate to an increase of roughly 11°F (6° C), enough to “bring extreme food and water shortages in vulnerable countries and cause floods that would displace hundreds of millions of people.” Other experts agree “we’re at the very top end of the worst case [emissions] scenario.” Carbon levels of 350 ppm or lower are required to “preserve a planet similar to that on which...life on Earth is adapted.”5
“It is also important to note that even reducing emissions 80 percent by 2050 will not eliminate all serious risks and damages.”6
- Methane is escaping from the melting permafrost.
Gaseous methane has recently begun entering the atmosphere after escaping from melting permafrost in many Arctic regions. Methane is 20 times more potent than carbon dioxide as a greenhouse gas. The Arctic region as a whole has seen a 4°C rise in average temperatures over recent decades.4
- Coral reefs are dying.
On the whole, coral reefs are dying. One quarter of the world's reefs have already been lost, and those remaining are under stress from pollution, sedimentation, destructive fishing practices and global climate change. Reefs have existed on Earth for millions of years, but up to 70% of the world's shallow reefs could be gone in the next few decades.25
Reefs harbor at least one quarter of all marine life. Besides giving habitat to creatures with their own inherent right to live, reefs comprise about 10% of the world's fisheries, with much of the catch feeding protein-starved people in underdeveloped countries. Because they support so much biodiversity, reefs, like tropical rain forests, offer excellent prospects for new medicines and natural compounds that can benefit humanity. Finally, reefs provide a natural seawall that protects many coastal populations from tides, storm surges and hurricanes.
- Oceanic dead zones found all over the world are increasing at alarming rates.
- Oceanic oxygen-deprived "dead zones" have been increasing since the 1970s and now number nearly 150, threatening fisheries as well as humans who depend on fish. These "dead zones" are caused by excess nitrogen from farm fertilizers, sewage, and emissions from vehicles and factories. In what experts call a “nitrogen cascade,” the contaminants flow untreated into oceans and trigger the proliferation of plankton, which in turn depletes oxygen in the water. While fish might flee this suffocation, slow moving, bottom-dwelling creatures like clams, lobsters and oysters are less able to escape.26
- Corporations dump horrifying amounts of toxins into the oceans.
- Corporations “dump on equivalent, at the smallest, 5,000,000 gallons per day of toxins...everything from benzene, acrylic nitrile, mercury, copper, you name it, they got it.”27
- Phytoplankton populations are collapsing.
Research published in the journal Nature reveals there has been a 40% decline in ocean phytoplankton populations since 1950. These creatures are the foundation of the marine food web, produce as much as half the world's oxygen, and absorb vast amounts of carbon dioxide.3
- The oceans are acidifying.
Oceans are acidifying 10 times faster today than 55 million years ago, when a mass extinction of marine species occurred.34
- One-half of all species are threatened with extinction, primarily by industrial activity.
If nothing is done, one-half of all species will be gone by the end of the century14, including 1 in 4 mammal species, 1 in 8 bird species8, and 1 in 3 amphibian species. Just two years ago, only 1 in 4 mammal species were threatened with extinction.9
"The current extinction event is due to human activity, paving the planet, creating pollution, many of the things that we are doing today." The Earth might well lose half of its species in our lifetime.7
- The rate of extinction is increasing.
For the past 300 million years, excluding this century, approximately one species went extinct every four years. Today, scientists see one species going extinct every 15 minutes.11
Species extinction has increased to rates of 10 to 100 times greater than that of 30 years ago.12 Furthermore, current species extinction rates are thought by some experts to be grossly underestimated due to mathematical misdiagnosis.13
- The planet has lost 80% of its forest cover to deforestation.
The planet has already lost 80% of its forest cover to deforestation, and at the alarming rate at which trees are being cut, it won’t take much time for that figure to reach the 100% mark. The West African region, which boasted of lush green tropical forests in the 19th century, has been stripped of 90% of its forest cover over the last century. The same trend of deforestation continues in the two remaining rainforest biomes in South America and Asia respectively.37 The U.S. has lost 95% of its old growth forests.29
70 countries in the world no longer have any intact or original forests.15
- Deforestation continues at incredibly unsustainable levels.
More than 72 acres of rainforest are destroyed every minute15, approximately enough to cover the entire state of Florida each year.
Between 8 and 16 billion trees are cut down every year. That averages to 22-44 million trees per day, 916,000 trees cut down per hour, 15,000 trees cut down per minute, 250 trees cut down per second.31
- Formerly healthy land becomes desert at frightening rates
Every hour, more than 500 acres of land become desert. More than 4.8 billion acres worldwide are degraded. Loss of arable lands is estimated at 30 to 35 times the historical rate,38 which was already dramatically higher than the natural rate.
- Topsoil is lost far faster than it can be recreated.
More than 75% of the topsoil that existed worldwide when Europeans first colonized North America is now gone. Over 300 tons of topsoil are lost worldwide every minute. It takes an average of 400 years for a forest to create enough topsoil able to sustain crops.17
- Agriculture is the most important cause of deforestation and soil loss.
- Subsistence farming accounts for 46% of world deforestation, commercial agriculture for 32%, and logging for 14%.37 Cultivation of annual crops leads to massive soil loss.
- Dioxin is found in almost every mother's breast milk.
- A 1987 study showed nearly every mother has dioxin, a known carcinogen, in her breast milk. The level of the most toxic form of dioxin in breast milk was enough to cause cancer eventually in 27 out of every million children who nurse for a year.19 Samples from mothers also show contaminants of over 350 chemicals from substances such as perfumes, suntan lotion, and pesticides.20
- More than a dozen highly toxic chemicals are present in our environment in large quantities.
- Industrial technology has polluted our environment with these, and more:23
- PCBs (Poly-chlorinated biphenyls), which are carcinogens
- Dioxins, which are carcinogens
- Furans, which are carcinogens
- Aldrin, which is both a carcinogen and mutagen
- Dieldrin, which is a carcinogen and linked to Parkinson’s disease
- DDT, which is a carcinogen and xenoestrogen (artificial estrogen)
- Endrin, which is toxic and adversely affects the nervous system
- Chlordane, which damages the nervous system, digestive system, and liver, as well as being highly toxic
- Hexachlorobenzene (HCB), which is a carcinogen
- Mirex, which is a carcinogen
- Toxaphene, which harms the lungs, kidneys, and nervous system
- Heptachlor, which harms the liver and decreases fertility
The oceans help sustain our atmosphere and provide a large portion of the world’s oxygen. When the healthy functioning of these systems becomes threatened, so does the very health of the biosphere.
In 1997, the US Academy of Sciences estimated 6.4 million tons of annual global input of marine litter into the oceans.28
More than 100 species go extinct every day.10
Forests are critical parts of many healthy ecosystems, as they prevent soil erosion and support healthy topsoil. Trees also act as huge carbon sinks, sequestering as much as 10% of the annual carbon dioxide emissions in the U.S.18
Industrial processes are contaminating the bodies of nearly every individual in this culture, as well as many others. Although the levels of toxins found in the body are often deemed as acceptable, their presence is a clear sign of the unhealthy nature of this culture's practices. We should not be surprised by the enormous increase in cancer rates in the United Sates when nearly every baby is receiving carcinogens from their mother's breast milk.
The percentage of girls under 8 years old with swollen breasts or pubic hair has gone from 1% to over 6% in just the last 8 years.21
Male sperm counts have dropped more than 30% in the past 60 years.22
