Some of the first questions which come up in any practical discussion of space colonization are questions of economics. Suppose we go out and settle on a convenient asteroid with our little spaceship, what do we do when we get there? How do we make a living? What can we expect to export in order to pay for necessary…
For me, the most paralyzing news was that Nature was no conservationist. It needed no help from us in taking the planet apart and putting it back together some different way, not necessarily improving it from the viewpoint of living things. It set fire to forests with lightning bolts. It paved vast tracts of arable…
It is both a sad and a happy fact of engineering history that disasters have been powerful instruments of change. Designers learn from failure. Industrial society did not invent grand works of engineering, and it was not the first to know design failure. What it did do was develop powerful techniques for learning from…
Given that 143 million people visit accredited zoos and aquariums each year, the Association of Zoos and Aquariums is entitled to the claim that the association is building North America's largest wildlife conservation movement. Zoos and aquariums are mainstream environmental organizations. Their supporters, some 48…
We formerly remarked, as a singular phaenomenon, that the animals in the southern provinces of the New Continent, are small in proportion to those in the warm regions of the Old. There is no comparison between the size of the elephant, the rhinoceros, the hippopotamus, the camelopard, the camel, the lion, the tiger…
Most human and natural communities now consist both of long-term residents and of new arrivals, and ecosystems are emerging that never existed before. It is impractical to try to restore ecosystems to some ‘rightful' historical state. For example, of the 30 planned plant eradication efforts undertaken in the Galapagos…
Many plants new to North America first sprouted up alongside wharves and shipyards. From there they made their way inland along new roads hacked out of the wilderness, and later along canals and railroad embankments, taking up residence in any sort of disturbed soil. Native plants adapted to quiet precolonial forests…
This much is certain: The future of the planet wall not be a reprise of the past, a return to "a state of nature." The future will certainly be technological, increasingly globally homogeneous, and, in the short run at least, will embody the connectivity of the computer chip and the contrivances of genetic…
