By Charlie Stross Being a guy who writes science fiction, people expect me to be well-informed about the current state of the field—as if I'm a book reviewer who reads everything published in my own approximate area.
Half of the world's wetlands were lost last century.
Logging and conversion have shrunk the world's forests by as much as half. Some 9 percent of the world's tree species are at risk of extinction; tropical deforestation may exceedsquare kilometers per year.
Fishing fleets are 40 percent larger than the ocean can sustain. Nearly 70 percent of the world's major marine fish stocks are overfished or are being fished at their biological limit.
Soil degradation has affected two-thirds of the world's agricultural lands in the last 50 years. Some 30 percent of the world's original forests have been converted to agriculture.
Sincethe global economy has tripled in size and population has grown by 30 percent to 6 billion people. Dams, diversions or canals fragment almost 60 percent of the world's largest rivers.
Twenty percent of the world's freshwater fish are extinct, threatened or endangered. People and Ecosystems, the Fraying Web of Life United Nations Development Programme A pioneering analysis of the world's ecosystems reveals a widespread decline in the condition of the world's ecosystems due to increasing resource demands.
The analsysis, by the World Resources Institute WRI warns that if the decline continues it could have devastating implications for human development and the welfare of all species. The analysis examined coastal, forest, grassland, and freshwater and agricultural ecosystems.
The health of the each ecosystem was measured, as based on its ability to produce the goods and services that the world currently relies on. The analysis shows that there are considerable signs that the capacity of Earth's ecosystems to produce many of the goods and services we depend on is rapidly declining.
To make matters worse, as our ecosystems decline, we are also racing against time since scientists lack baseline knowledge needed to properly determine the conditions of such systems. New Analysis of World's Ecosystems Reveals Widespread Decline ENN Will our great- grandchildren inherit a desiccated husk of a once shimmering planet, and curse us for a legacy of droughts, plagues,storms and hardscrabble moonscapes?
The four-fold increase in humans and the advent of the consumer society - have made the end of the millennium a cusp of history. Affluent consumers in Hong Kong want exotic fish and presto! Poachers in the Philippines destroy vital reefs to meet that demand. Millions of workers in China and Russia are plagued with pollution-related ailments.
We need your help to ask President Barack Obama and the Environmental Protection Agency to get working on a bold plan to curb ocean acidification.
Carbon dioxide pollution is also being absorbed by the ocean, causing its chemistry to change and become more acidic.JOURNALS OF TWO EXPEDITIONS OF DISCOVERY IN NORTH-WEST AND WESTERN AUSTRALIA, DURING THE YEARS , , AND , Under the Authority of Her Majesty's Government.
Journal Article review on “The Origin of Old-Earth Geology and its Ramifications for Life in the 21st Century.
By: Dr. Terry Mortenson, Aig-U.S. The Origin of Old-Earth Geology and its Ramifications for Life in the 21st Century, by Doctor Terry Mortenson, is a journal article that claims to be about Old Earth Geology history, and perceived consequences that this ideology has inflicted on our society today.
Liberty University Introduction This document is a journal article review providing a brief synopsis, observed strengths, and observed weaknesses of Doctor Mortenson’s “The Origin of Old-Earth Geology and its Ramifications for Life in the 21st Century”.
The Origin of Old-Earth Geology and Its Ramifications for Life in the 21st Century. April 7, Journal Article Review Introduction In this paper I will discuss and review Dr.
Terry Mortenson’s article about The Origin of Old-Earth Geology and its Ramifications for Life in the 21st Century. The Bible and an Old Earth. Inserting vast ages into the Bible’s first chapter sets it at odds with modern secular scientific opinion regarding the order of events.
