Today’s Mass Extinction: The Call of Life

WASHINGTON: Chances of humans benefiting from nature are receding, as natural habitats are becoming less productive due to the gradual extinction of plant species.

Many scientists now argue that the Earth is in the middle of the sixth mass extinction in the history of life. Some estimates suggest that as much as 50 per cent of all known species could be extinct by the end of this century.

According to an international team of scientists, new analysis shows plant communities as being composed of both stars and supporting players.

Some plants are so productive that they dominate the productivity of natural habitats. Supporting species complement key players and enhance the productivity of plant communities even further.

Lead authors of the study – Michel Loreau of McGill University in Montreal and Andy Hector, an assistant professor at the University of Zurich – further go on to say that species extinction is one of the most pronounced environmental changes of our time.

“Our analysis provide the most comprehensive evidence yet that natural habitats with a greater variety of plant species are more productive. Our analysis show that diverse communities are more productive because plants are ‘complementary’ in how they use biological resources. In other words, different plant species play unique roles in the environment,” said Loreau.

Assistant Professor Hector said: “The results of our analyses suggest that plant communities operate much like a soccer team. Teams are composed of both star players and supporting players. You probably can’t win many games if you lose your top striker because she or he is the most productive player and can dominate a game. But strikers cannot win games by themselves. They need great passes from supporting players and solid goal-tending if the team is going to be successful as a whole.”

“The process by which plants grow and produce more plant biomass is one of the most fundamental biological processes on the planet,” added Bradley Cardinale, assistant professor of biology at the University of California, Santa Barbara.

Plant productivity regulates the ability of nature to take greenhouse gases like carbon dioxide out of the atmosphere, as well as the ability of habitats to produce oxygen, food, fibre, and bio-fuels, according to the authors of the study.

“Therefore, species extinctions could compromise the benefits that nature provides to society,” said Cardinale.

The study summarized the results of 44 experiments from around the world that simulated plant species extinction and showed that ecosystems with fewer species produce up to 50 percent less plant biomass than those with more “natural” levels of diversity.

Cutting Down Trees to Save the Rainforest

Sustainable Forestry has been a solution in Papua New Guinea.  (See Video Below) The management planned developed by locals and environmental groups mimic the natural dynamic of the forest. By carefully observing the natural cessation of different native trees and their different roles in the forest ecosystem, they recreated the natural processes in the forest. Through the execution of this plan the forest areas were fully regenerated with virtually no long term negative effects on the forest. At the same time providing a sustainable income source for the people living on the land.

The Secrects of El Dorado and the Magic of Terra Preta

Documentary Film Below

Many soil scientists insist an ancient Amerindian agrarian society will soon make a huge impact on the modern world. They say once the intricacies and formulation of the society’s “terra preta” (dark earth) is unlocked, the benefits will help stop environmental degradation and bring fertility to depleted soils. Developing and developed nations will benefit.


The story goes that in 1542, while exploring the Amazon Basin near Ecuador in search of El Dorado, Spanish conquistador Francisco de Orellana began checking the area around one of the Amazon’s largest rivers, the Rio Negro. While he never found the legendary City of Gold, upon his return to Spain, Orellana reported the jungle area held an ancient civilization – a farming people, many villages and even massive, walled cities.

Later explorers and missionaries were unable to confirm Orellana’s reports. They said the cities weren’t there and only hunter-gatherer tribes roamed the jungles. Orellana’s claims were dismissed as myth.

Scientists who later considered Orellana’s claims agreed with the negative assessments. The key problem, they said, was large societies need much food, something Amazonia’s poor soils are simply incapable of producing. And without agriculture, large groups of people are unable to escape a nomadic existence, much less build cities.
