Restored bald eagles will kick them off Santa Cruz

The latest edition of the Nature Conservancy's quarterly magazine featured an article describing restoration efforts on Santa Cruz Island, sometimes referred to as The Galapagos of North America.

Bald eagles disappeared from the island in the 1960s. Just across the bay a chemical company had been making DDT and dumping it into waterways. A survey two decades later found a hundred tons of the stuff in local ocean sediments.

The bald eagles got nailed because they primarily prey on water species. Golden eagles took over the island and because they primarily prey on land-dwelling animals, the local fox population was being decimated. This is an example of how ecosystems unravel.

Bald eagles, which do not tolerate golden eagles in their territories, are being reintroduced to the island. Once reestablished they will drive off the golden eagles, thus sparing the endangered foxes.

Electric bike talk

This post is for all the nerds out there who keep sending me emails with technical questions. Consider it an update to my update.

I designed a new battery holder out of PVC sheet to replace the wooden box used on my first prototype. I also replaced a fried switch with one that has a higher current rating and designed a new wiring harness with quick disconnects. My lead-acid battery pack is already starting to take less charge and I have now relegated it to back-up status.

Animal rights and environmentalism should stay separate

I was going to write a post on animal rights a few months ago but thought better of it. I changed my mind and fluffed up what I had written in order to supplement (but not invalidate) the discussion initiated by Jason over here.

Environmentalism and animal rights should remain separate groups. Their interests, though sometimes related and even mutually beneficial, are just as often too disparate for a harmonious union. For example, hunters can make powerful conservationists (conservation being a major branch of environmentalism), but hunters and animal-rights activists mix worse than oil and water.

This article makes mention of the hundreds of thousands of goats that have finally been eliminated from the Galapagos Islands. By eliminated I mean: they were shot. Had an organized and well-funded animal-rights campaign arisen, accomplishing that task might have taken much longer, or cost a great deal more. Or it might not have happened at all. I use these goats as an analogy for the horse roundup mentioned in Jason's article. Both species of domesticated animal are the result of many thousands of years of genetic engineering by human beings to produce an animal of use to them. Neither has a place in the wild. The ecosystems they evolved in are human-generated.

Public should think twice about biofuels

The annual forest and biodiversity clearing exercise in Indonesia is drawing to a close. Here's an article telling us that a thousand or so orangutans were burned to death this time around.

Every year, year after year, like a broken record or a slow motion horror movie, we sit around reading articles describing the extinction of the wild orangutan and other unique lifeforms. We human beings have just got to scratch that itch, that insatiable urge to increase one's wealth, position, rank, standing, station, prestige, fame, prominence, distinction, importance, renown, influence, eclat, celebrity, esteem, glory, status, whatever.
