A global synthesis reveals biodiversity loss as a major driver of ecosystem change. Mariana Trench Life Forms More Diverse Than You Might Imagine. By Jennifer Frazer The deepest, darkest, scariest place on the maps I loved pondering as a child was a crescent-shaped canyon in the western Pacific Ocean.
It was called the Mariana Trench, and at the very, very bottom was the lowest point on Earth’s surface, the Challenger Deep. Its floor was seven terrifying miles down. What was down there? It was fun to imagine. Tara Expeditions - « BIODIVERSITY IS THE HISTORY OF LIFE ON EARTH » Environment and Biodiversity. Environment and Biodiversity.

Increasing evidence suggests that loss of Earth’s biological diversity will compromise our planet’s ability to provide the goods and services societies need to prosper.
A biosphere designed for the 1967 World Expedition on St Helen's Island in Montreal, QuebecWIKIMEDIA, RENE EHRHARDTRecall the biosphere experiments from the 1990s, the most famous of which was perhaps Biosphere II. Philanthropist Ed Bass provided $200 million to construct the largest completely enclosed ecosystem ever created. Biologists and engineers spent 4 years designing and landscaping Biosphere II to have all of the systems needed to sustain life: agriculture for food production, rainforests to regulate the artificial atmosphere, even a mini-ocean to control temperature. On September 26th, 1991, eight researchers were locked inside the airtight, closed environment. Almost immediately after, levels of CO2 inside Biosphere II began to skyrocket and fluctuate wildly.

The world's biodiversity is down 30 percent since the 1970s, according to a new report, with tropical species taking the biggest hit.
And if humanity continues as it has been, the picture could get bleaker. Humanity is outstripping the Earth's resources by 50 percent — essentially using the resources of one and a half Earths every year, according to the 2012 Living Planet Report, produced by conservation agency the World Wildlife Fund (WWF). Colby Loucks, the director of conservation sciences at WWF, compared humanity to bad houseguests. "We're emptying the fridge, we're not really taking care of the lawn, we're not weeding the flower beds and we're certainly not taking out the garbage," Loucks said.

Among conservationists, policy-makers, and the public, there is great debate about whether the establishment of national parks and reserves in developing nations causes poverty or helps to alleviate it.
While opponents claim that protected areas limit agricultural development and the harvesting of natural resources, supporters contend that protected areas generate tourism income and improve infrastructure in the surrounding areas. A new study in PNAS this week suggests that, in the long term, establishing protected areas in developing nations does reduce poverty in local communities. The authors criticize earlier studies that have found correlations between poverty and protected areas for omitting confounding variables that may account for the apparent link. What is IUCN?
