In 1992 scientists warned of global ecosystem collapse. In 2017, conditions are worse.
This second warning is even more urgent about changes needing to be made because conditions have worsened since 1992 significantly.
“Soon it will be too late to shift course away from our failing trajectory, and time is running out. We must recognize, in our day-to-day lives and in our governing institutions, that the Earth with all its life is our only home.”
Among the negative trends are:
Declining Freshwater availability: Per capita freshwater availability is less than half of levels of the early 1960s with many people around the world suffering from a lack of fresh clean water. Much of this decrease in available water is due to an accelerated pace of human population growth and increases in agricultural water use. It is likely that climate change will have an overwhelming impact on the freshwater availability through alteration of the hydrologic cycle and water availability. Future water shortages will be detrimental to humans, affecting everything from drinking water, human heath, sanitation, and the production of crops for food.
Unsustainable marine fisheries: In 1992, the total marine catch was at or above the maximum sustainable yield and fisheries were on the verge of collapse, peaking in 1996 at 130 million tons in 1996 and has been declining ever since , despite an increase in fishing effort
A 75 % increase in the number of ocean dead zones. Coastal dead zones which are mainly caused by fertilizer runoff and fossil-fuel use, are killing large swaths of marine life. Dead zones with hypoxic, oxygen-depleted waters, are a significant stressor on marine systems and identified locations have dramatically increased since the 1960s, with more than 600 systems affected by 2010.
Deforestation. A loss of nearly 300 million acres of forestland, much of it converted for agricultural uses. Between 1990 and 2015, total forest area decreased from 4,128 to 3,999 million hectares, a net loss of 129 million hectares, approximately the size of South Africa.
Dwindling biodiversity. The world’s biodiversity is vanishing at an alarming rate and populations of vertebrate species are rapidly collapsing. Global ly,fish, amphibians, reptiles, birds, and mammals declined by 58% between 1970 and 2012. Freshwater, marine, and terrestrial populations declined by 81%, 36%, and 35% respectively.
Continuing significant increases in global carbon emissions and average temperatures
Overpopulation. Over 2 billion people have been born since 1992 – a 35 % rise in human population. From; http://energyskeptic.com/2017/world-scientists-warning-to-humanity-a-second-notice/
