Part One of a Six parts on YouTube of BBC Documentary, How Many people Can Live on Planet Earth? featuring David Attenborough (Follow on YouTube for the other five parts).
This BBC documentary is about us – the human beings living on the planet earth. Naturalist Sir David Attenborough investigates if an ongoing rise in population growth is possible or if we have to introduce birth control to prevent overpopulation. The size of the human population is currently nearly 7 billion people, which is much more than the 2.5 billion in 1950. Until 2050 the UN is expecting about 9 Billion people to be living on this world. One of the big reasons is, that people are becoming older and older, not necessary an increase in family size. The rise of China is one of the big roles, but also the population of other countries will increase. But can we provide enough foot and shelter for all those people without damaging our nature for ever?
If the oceans go down, it’s game over.
– Dr. Alex Rogers
A high-level international workshop convened by IPSO met at the University of Oxford earlier this year. It was the first inter-disciplinary international meeting of marine scientists of its kind and was designed to consider the cumulative impact of multiple stressors on the ocean, including warming, acidification, and overfishing.
The 27 participants from 18 organisations in 6 countries produced a grave assessment of current threats – and a stark conclusion about future risks to marine and human life if the current trajectory of damage continues: that the world’s ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history.
Delegates called for urgent and unequivocal action to halt further declines in ocean health.
If the current actions contributing to a multifaceted degradation of the world’s oceans aren’t curbed, a mass extinction unlike anything human history has ever seen is coming, an expert panel of scientists warns in an alarming new report.
The preliminary report from the International Programme on the State of the Ocean (IPSO) is the result of the first-ever interdisciplinary international workshop examining the combined impact of all of the stressors currently affecting the oceans, including pollution, warming, acidification, overfishing and hypoxia.
“The findings are shocking,” Dr. Alex Rogers, IPSO’s scientific director, said in a statement released by the group. “This is a very serious situation demanding unequivocal action at every level. We are looking at consequences for humankind that will impact in our lifetime, and worse, our children’s and generations beyond that.”
The scientific panel concluded that degeneration in the oceans is happening much faster than has been predicted, and that the combination of factors currently distressing the marine environment is contributing to the precise conditions that have been associated with all major extinctions in the Earth’s history.

I have a copy of this in my personal papers since 1968.
On Tuesday, the conservation group American Rivers named the Chicago River one of the “most endangered rivers” in the country.

FRONTLINE 2009 report: POISONED WATERS
FRONTLINE REPORTS: More than three decades after the Clean Water Act, iconic American waterways like the Chesapeake Bay and Puget Sound are in perilous condition and facing new sources of contamination.
With polluted runoff still flowing in from industry, agriculture and massive suburban development, scientists note that many new pollutants and toxins from modern everyday life are already being found in the drinking water of millions of people across the country and pose a threat to fish, wildlife and, potentially, human health.
In Poisoned Waters, Pulitzer Prize-winning journalist Hedrick Smith examines the growing hazards to human health and the ecosystem.
Through interviews with scientists, environmental activists, corporate executives and average citizens impacted by the burgeoning pollution problem, Smith reveals startling new evidence that today’s growing environmental threat comes not from the giant industrial polluters of old, but from chemicals in consumers’ face creams, deodorants, prescription medicines and household cleaners that find their way into sewers, storm drains and eventually into America’s waterways and drinking water.
“The environment has slipped off our radar screen because it’s not a hot crisis like the financial meltdown, war or terrorism,” Smith says. “But pollution is a ticking time bomb. It’s a chronic cancer that is slowly eating away the natural resources that are vital to our very lives.”
In Poisoned Waters, Smith speaks with researchers from the U.S. Geological Survey (USGS), who report finding genetically mutated marine life in the Potomac River. In addition to finding frogs with six legs and other mutations, the researchers have found male amphibians with ovaries and female frogs with male genitalia. Scientists tell FRONTLINE that the mutations are likely caused by exposure to “endocrine disruptors,” chemical compounds that mimic the body’s natural hormones.
The USGS research on the Potomac River poses some troubling questions for the 2 million people who rely on the Washington Aqueduct for their drinking water.
