TOPICS: EXTINCTION, FROM THE WIRES, SOME SPECIES WILL LIKELY SURVIVE
Abstract: Yet another warning (with nearly 15,000 references) the true believers of the world will consider and say, "Yes, all true, but..." followed by fine words that won't matter. Wordsmiths of the world are adept at numerous sleight of mind tricks. Some will politicize the warning to further their putative "solutions." Meanwhile the CDC reports that the American birth rate is the lowest it has been in 32 years. Anthropocene enthusiasts are deeply concerned. See page one.
COOS BAY (A-P) —
Meanwhile, on page 28 of global media coverage of the state of the world, the 1,500 page UN (IPBES) report links to the 40-page summary that maybe 0.001% of humans will actually read (but probably not spend too much time thinking about). Some highlights:
Three-quarters of the land-based environment and about two-thirds of the marine environment have been significantly altered by human actions. On average these trends have been less severe or avoided in areas held or managed by Indigenous Peoples and Local Communities [i.e. the marginalized living on the edge of industrial society are less empowered to alter their environment].
More than a third of the world’s land surface and nearly 75% of freshwater resources are now devoted to crop or livestock production [and much of the 25% is used to support urban and industrial sprawl, e.g. 130 gals/day/person for those living in Tucson AZ at the end of a 330 mile canal delivering water pumped 2,000 ft uphill from the Colorado River thanks to coal fired power plants].
The value of agricultural crop production has increased by about 300% since 1970 [as fossil fuels are turned into food], raw timber harvest has risen by 45% and approximately 60 billion tons of renewable and nonrenewable resources are now extracted globally every year – having nearly doubled since 1980.
Land degradation has reduced the productivity of 23% of the global land surface, up to US$577 billion in annual global crops are at risk from pollinator loss and 100-300 million people are at increased risk of floods and hurricanes because of loss of coastal habitats and protection.
In 2015, 33% of marine fish stocks were being harvested at unsustainable levels; 60% were maximally sustainably fished, with just 7% harvested at levels lower than what can be sustainably fished [e.g. surf perch in Oregon which cannot be commercially fished (yet)].
Urban areas have more than doubled since 1992 [the year of the first World Scientists' Warning to Humanity].
Plastic pollution has increased tenfold since 1980, 300-400 million tons of heavy metals, solvents, toxic sludge and other wastes from industrial facilities are dumped annually into the world’s waters, and fertilizers entering coastal ecosystems have produced more than 400 ocean ‘dead zones’, totalling more than 245,000 km2 (591-595) - a combined area greater than that of the United Kingdom [or Michigan].
Negative trends in nature will continue to 2050 and beyond in all of the policy scenarios explored in the Report, except those that include transformative change – due to the projected impacts of [1] increasing land-use change [e.g. agriculture, urban/industrial sprawl — by far the major cause of bio-diversity loss and mass], [2] exploitation of organisms and [3] climate change, although with significant differences between regions.
Life on Earth is the canary in our coal mine. The turning point (averaged slope >45 degrees, two hundred years before the Great Acceleration) coincides with the beginnings of the Industrial Revolution. But as Anthropocene Enthusiasts note, that is surely correlation, not causation. There is no convincing evidence that species extinction is caused by humans. But climate change is [isn't], so vote for ____ who has real solutions.
By the Numbers – Key Statistics and Facts from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Report
On Monday March 6th, 2019, the UN’s IPBES Global Assessment was released. This is the most comprehensive and authoritative assessment of Nature and its contributions to people—ever.
