20 Years after Rio Earth Summit: Ecologists Call for Preservation of Planet’s Remaining Biological Diversity

ANN ARBOR, Mich.— Twenty years after the Earth Summit in Rio de Janeiro, 17 prominent ecologists are calling for renewed international efforts to curb the loss of biological diversity, which is compromising nature’s ability to provide goods and services essential for human well-being.

Over the past two decades, strong scientific evidence has emerged showing that loss of the world’s biological diversity reduces the productivity and sustainability of natural ecosystems and decreases their ability to provide society with goods and services like food, wood, fodder, fertile soils, and protection from pests and disease, according to an international team of ecologists led by the University of Michigan’s Bradley Cardinale.

Ecosystem Effects of Biodiversity Loss Could Rival Impacts of Climate Change, Pollution

ANN ARBOR, Mich.— Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study from an international research team.

The study is the first comprehensive effort to directly compare the impacts of biological diversity loss to the anticipated effects of a host of other human-caused environmental changes.

The results highlight the need for stronger local, national and international efforts to protect biodiversity and the benefits it provides, according to the researchers, who are based at nine institutions in the United States, Canada and Sweden. (more…)

Earth in 20 Years

The world will face many challenges over the coming decades, not least among them environmental challenges. On the heels of Earth Day, we asked three leading researchers at the U to answer three questions for us in their specialties of sustainable agriculture, environmental justice, and economics and ecology.

Here’s what they had to say:

Jon Foley is the director of the U’s Institute on the Environment, which discovers solutions to Earth’s most pressing environmental problems. (more…)

What Triggers Mass Extinctions? Study Shows How Invasive Species Stop New Life

*Collapse of Earth’s marine life 378 to 375 million years ago holds key*

An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published in the journal PLoS ONE.

The study of the collapse of Earth’s marine life 378 to 375 million years ago suggests that the planet’s current ecosystems, which are struggling with biodiversity loss, could meet a similar fate. (more…)
