Vertebrate species decline by ⅓ in 1970-2003 and Earth can’t keep up regeneration

Wednesday, February 24th, 2010

The “Human footprint too big for nature” report issued by the World Wide Fund for Nature (WWF) on 24 October 2006, confirmed concerns from the previous year noting that “Already resources are depleting, with the report showing that vertebrate species populations have declined by about one-third between 1970 and 2003. At the same time, humanity’s Ecological Footprint (that is, the demand people place upon the natural world) has increased to the point where the Earth is unable to keep up in the struggle to regenerate.

10-30% of mammal, bird and amphibian species are endangered

Wednesday, February 24th, 2010

The 2005 Millennium Ecosystem Assessment Report noted there has been a substantial and largely irreversible loss in the diversity of life on Earth, with some 10-30 percent of the mammal, bird and amphibian species currently threatened with extinction, all due to human actions.

Phytoplankton and forests are the two major systems that trap and eliminate carbon

Wednesday, February 24th, 2010

A report issued by Jaan Suurküla, M.D, Chairman of Physicians and Scientists for Responsible Application of Science and Technology (PSRAST) noted that there are two major systems that can trap and eliminate carbon in the atmosphere. The largest one is phytoplankton in the oceans. The second largest is forests.

One million metric tons of fish thrown away annually in US

Wednesday, February 24th, 2010

For every 5 pounds of fish caught by US commercial fisheries, one pound is dumped dead and wasted. More than one million metric tons of fish is thrown away annually in USA. A Gulf of Mexico shrimp fishery discards 472,000 metric tons or one billion pounds of fish. Shrimp and fish trawl fisheries are responsible for 78% of all discards in US fisheries.

100 million sharks, vitally important to ocean ecosystems, killed annual

Wednesday, February 24th, 2010

Sharks have existed for 400 million years. Now, only two sanctuaries are left for sharks. Though sharks kill only 5 people annually, humans kill 100 million sharks annually for a billion dollar shark industry.

Global marine protection would cost less than current commercial fishing subsidies

Wednesday, February 24th, 2010

Bottom trawling can plough furrows up to 6m wide and 150cm deep, for many kilometres across the seabed. Some areas are trawled this way five times a year; they are turned over much more often than arable fields. This has had a disastrous effect on the habitat that extends from below to the seabed to a short distance above it, and for the species living there.

A recent survey found that running a global system of marine protected areas covering 30% of the oceans would cost between £6.5 and £7.5 billion a year. This is less than the £8 to £16 billion spent globally each year on subsidies to commercial fisheries.

90% of all large fishes extinct in past half century

Thursday, February 18th, 2010

A new global study concludes that 90 percent of all large fishes have disappeared from the world’s oceans in the past half century. Another cause for extensive fish extinction is the destruction of coral reefs. This is caused by a combination of factors, including warming of oceans, damage from fishing tools and infections of coral organisms promoted by ocean pollution. It will take hundreds of thousands of years to restore what is now being destroyed in a few decades.
