Falling on deaf ears???
William Ripple of Oregon State University's College of Forestry said that he came across the 1992 warning last February, and noticed that this year happened to mark the 25th anniversary.
Together with his graduate student, Christopher Wolf, he decided to revisit the concerns raised then, and collect global data for different variables to show trends over the past 25 years. Ripple found:
A decline in freshwater availability.
Unsustainable marine fisheries.
Ocean dead zones.
Forest losses.
Dwindling biodiversity.
Climate change.
Population growth.
"The scientists around the world are very concerned about the state of the world, the environmental situation and climate change."
"Since 1992, carbon emissions have increased 62 per cent," Ripple said. "And the global average temperature change has paralleled that. Also since 1992, we have two billion more people on Earth, which is a 35 per cent increase."
