Bye-Bye Birdies

North American Species at High Risk

The 2016 annual Audubon Great Backyard Bird Count in February and a report compiled by the North American Bird Conservation Initiative show that more than a third of all North American bird species are at risk of becoming extinct unless significant action is taken, especially ocean and tropical birds. The governments of Canada, the United States and Mexico created the North American Bird Conservation Initiative in 1999.

More than half the species that rely on oceans and tropical forests are on a special watch list because of small and declining populations, limited ranges and severe threats to their habitats. The report pinpoints invasive predators such as rats and cats on nesting islands, as well as overfishing, pollution and climate change. Ways to address the problem include removing predators, expanding protected marine areas and reducing the amount of plastic products that end up in the ocean and can trap or choke birds.

Many species such as long-distance migratory shore birds in coastal, grassland and arid habitats are declining steeply. The main causes are rising sea levels, coastal development, encroaching human activity and oil spills.

Ocean Watch

This year scientists discovered a new whale species in the Bering Sea and long-living orcas in the Pacific, even as dolphins in China, Hong Kong and Gulf of California waters are rapidly disappearing.

Extinction Scenario

The risk of humans disappearing from the Earth is estimated at one-tenth of a percent every year, say environmental biologists, but rising temperatures and populations may push that probability up to 3 percent.

Greening Planet

In the last 33 years, one quarter to a half of Earth’s vegetated lands have become more dense with living plants, which can help counter rising carbon emission levels.

Wise Woodsmen

Products linked to deforestation will no longer be purchased by Norway’s public agencies.
