Industrialized fishing contributed significantly to mass extinction

Thursday, February 18th, 2010

A report issued by Jaan Suurküla, M.D, Chairman of Physicians and Scientists for Responsible Application of Science and Technology (PSRAST) noted that industrialized fishing has contributed significantly to mass extinction due to repeatedly failed attempts to limit fishing.

Global warming could accelerate next couple of years with no time for adaptation

Thursday, February 18th, 2010

The report “Abrupt Climate Change: Inevitable Surprises” by the US National Academy of Sciences, the US’s most august scientific body, suggests that a catastrophe is imminent. It is possible that the global warming trend projected over the course of the next 100 years could, all of a sudden and without warning, dramatically accelerate in just a handful of years – forcing a qualitative new climatic regime which could undermine ecosystems and human settlements throughout the world, leaving little or no time for plants, animals and humans to adjust.

World’s freshwater systems are imperilled in supporting human, plant and animal life

Thursday, February 18th, 2010

The UN report on livestock’s impact on biodiversity states that “…The world’s freshwater systems are so degraded that their ability to support human, plant and animal life is greatly imperilled. In the 20th century, half the world’s wetlands are estimated to have been converted to agriculture and urban areas, filled and drained to combat diseases such as malaria, or lost entirely. The conversion of coastal ecosystems to agriculture and aquaculture, along with other pressures such as erosion and pollution, are reducing mangroves, coastal wetlands, sea grass areas and coral reefs at an alarming rate.”

Only 4% of world’s oceans free from human impact: 40% heavily impacted

Thursday, February 18th, 2010

Only 4% of world’s oceans remain free from human impact in 2008, according to a study in the journal Science, and 40% have been heavily impacted. One-tenth of sharks, tuna, cod and other predators have disappeared, affecting the marine food system. Those fish that eat starfish have disappeared, thus starfish numbers multiply, and they graze on coral resulting in larger reef disappearance in the past 30 years.  There has also been a large rise in algae, bacteria and jellyfish populations due to a lower number of predators.

169 out of 415 coastal areas are “dead” and 233 are experiencing eutrophication

Thursday, February 18th, 2010

The Washington-based World Resources Institute identified 415 over-enriched – or “eutrophic” – coastal areas throughout the world. Of these, 169 are depleted of oxygen, creating “dead zones” that are unable to support marine life. Another 233 of the systems identified are experiencing one or more symptoms of eutrophication, including toxic algal blooms, loss of biodiversity, and die-off of coral reefs.

Cattle responsible for 14% of world’s deforestation and 80% of Amazon’s deforestation

Thursday, February 18th, 2010

Greenpeace has recently released the report on ‘Slaughtering the Amazon’. The cattle sector in the Brazilian Amazon is responsible for 14% of the world’s annual deforestation. According to the Brazilian government: ‘Cattle are responsible for about 80% of all deforestation’ in the Amazon region.

Agricultural practices have caused:

  • Deprivation of diverse species of food sources
  • Expansion of dead zones or oxygen-depleted zones in the tropical Atlantic and Pacific.

Loss of forests = Loss of species

Thursday, February 18th, 2010

Loss of forests equates to a loss of many species. Brazil has around 55,000 species of flora, or 22% of the world’s total. India has about 46,000 species of flora and some 81,000 animal species or 8% of the world’s biodiversity.

Livestock direct cause of desertification due to overgrazing and overstocking

Thursday, February 18th, 2010

Livestock also directly contribute to habitat change as overgrazing and overstocking accelerate desertification.

Livestock uses 70% of all agricultural land on the planet

Thursday, February 18th, 2010

Raising animals for food requires vast tracts of land. Forests are thus being destroyed for growing feed crops and grazing of animals that feed us. This leads to DEFORESTATION.

According to the United Nations’ “Livestock’s Long Shadow” Report states that livestock production accounts for 70 percent of all agricultural land and 30 percent of the ice-free land surface on the planet.

Climate change, pollution and land use changes major drivers of biodiversity loss

Thursday, February 18th, 2010

According to the 2005 “Millennium Ecosystems Assessment, Ecosystems and Human Well-Being: Biodiversity Synthesis” report issued by the Washington-based World Resources Institute, the most important direct drivers of biodiversity loss and ecosystem service changes are: habitat change, such as land use changes, physical modification of rivers or water withdrawal from rivers, loss of coral reefs and damage to sea floor resulting from trawling; climate change; invasive alien species; overexploitation; and pollution.
