So 25 years after the original āalliance of world scientistsā letter, which was 20 years after āthe limits to growthā from the club of rome(not one bit disproved), how have things changed? Nothing to worry about if the press reporting is anything to go by(I have waited and one article hidden in the independent is all i have seen).
The authors of the 1992 declaration feared that humanity was pushing Earthās ecosystems beyond their capacities to support the web of life. They described how we are fast approaching many of the limits of what the Ābiosphere can tolerate Āwithout Āsubstantial and irreversible harm. The scientists pleaded that we stabilize the human population, describing how our large numbersāswelled by another 2 billion people since 1992, a 35 percent increaseāexert stresses on Earth that can overwhelm other efforts to realize a sustainable future. They implored that we cut greenhouse gas (GHG) emissions and phase out fossil fuels, reduce deforestation, and reverse the trend of collapsing biodiversity.
How are we getting on with biodiversity?
90% of Big Ocean Fish gone since 1950.
80% of Antarctic Krill gone since 1975.
80% of Western Gorillas gone since 1955.
60% of Forest Elephants gone since 1970.
50% of Great Barrier Reef gone since 1985.
40% of Giraffes gone since 2000.
30% of Marine Birds gone since 1995.
70% of Marine Birds gone since 1950.
28% of Land Animals gone since 1970.
28% of All Marine Animals gone since 1970.
97% ā Humans & Livestock are 97% of land-air vertebrate biomass.
10,000 years ago we were 0.01% of land-air vertebrate biomass.
Not so good then and thatās just a drop in the ocean of the destruction we have meted out to the only thing that keeps us alive(our biosphere).
Our lazy self delusion really does know no bounds.
