How to Send a Finch Extinct

Australia’s southern black-throated finch: Going, going …

This one caught my eye because it’s such a pretty bird, and because of the mindlessness with which Australia is letting human development drive it to extinction.

The state of Queensland and Australia’s federal government have allowed more than 1900 square miles of potential finch habitat to be cleared without anybody asking: Is this really a good idea? Almost 800 developments have been proposed and only one was turned down for its unacceptable impact on the finch, which has now vanished from 80 percent of its original habitat. Still in the works, five new coal mines in the last remaining high quality finch habitat.

It’s kind of amazing in a country that just this month is experiencing fish, wild horse, and bat die-offs  because of climate change.  (“Their brain just fries.“)

There’s a Senate hearing in Brisbane Friday on the…

15 Reasons Why You Should Study Environmental Science

Motivation, & the Environment

We live in an age that has a lot environmental challenges threatening the existence of living and non-living things. This Earth in which we breathe, eat and live, is not as healthy as it was in the distant past; so the major reason why you should study environmental science is because it will make you more aware and sensitive about happenings in the Earth’s environment; furthermore, it’ll update you about the environmental issues affecting everything in it, and which may likely continue to do so throughout the lives of its inhabitants.

It’s understandable if I sound biased when I state that environmental science is the most important subject because it cuts across all humans and other living things in the world. It is important to understand how the Earth works, how our activities affect its life-supporting capability, and how we can reduce the negative environmental impact on it; nobody has…

Helping Wildlife Survive the Sixth Mass Extinction

Preserving Critical Habitats Will Help More Wildlife Survive

This morning, an article by Andrew Suggitt (How wildlife will keep cool. . . .) made me think again about refugia. Earlier, I concluded that unlike ice ages, global warming would leave no refugia in which pockets of wildlife would survive. I was picturing a pervasive atmospheric impact instead of a discontinuous physical impact by tongues of glacial ice. I was wrong. The best habitats for wildlife, the ones along streams, in deep shaded canyons, and those in areas of diverse topography will sustain more wildlife as climate changes. Preserving those habitats is an essential goal for wildlife conservation.

Unfortunately, the best habitats for wildlife are the most desirable for humans. Worldwide, farming and home construction have destroyed the richest valley-floor habitats, and roads have filled the floors of canyons and narrow valleys. In the arid region where I live, livestock graze along rare desert streams and around lakes and marshes.

Preserving critical habitats is not a new idea. Conservation organizations have programs that identify and urge protection of important habitats. The National Audubon Society, for instance, has initiated the Climate Strongholds program that focuses on the needs of individual species. The program has strong citizen-scientist opportunities for participation. Read about it here.

Most wildlife species will be lost over the next few decades and centuries, but it will be possible to prevent some of the losses through preservation of critical habitats. As changing weather patterns force governments to respond to the climate emergency, nature conservation advocates must work hard to explain the critical role nature plays in human survival and to convince governments to protect the best wildlife habitats.

Half for Nature

Current climate projections suggest that global carrying capacity will drastically decline over the next few centuries. Human civilization as we know and imagine it now will not survive. Once the Earth’s energy budget stabilizes, people can begin to rebuild cities and networks and evolution can begin to rebuild natural plant and animal diversity. For the immediate future of 300 – 400 years, we must advocate for the “Best” for nature. Saving Half for Nature will be important as rebuilding begins.

I hope that saving the “Best” is a practical goal. Instead of plants and animals, there may be masses of people jammed into cool mountain canyons and camping along streams. Impacts of food and fuel gathering could block wildlife and make the mass extinction worse.

World Scientists Warning to Humanity

Scientists Warn of Global Dangers

Tomorrow is World Population Day. A good day to take note of the warnings coming from the world’s scientists.
“Humanity is on a collision course with Nature.
A damaged Nature will survive. We may not.
We must change course to avert an ecological disaster.”
Twenty-five years ago, 1700 scientists published a warning and recommendations for controlling environmental pollution and population growth. Except for global efforts to curtail ozone emissions, the warning had no effect. Last fall, more than 20,000 scientists issued a new warning urging efforts to change our disastrous path toward global ecosystem devastation.
