From page 116... ...
Yeast and chlorella, as such, don't hold much promise for human food and their indirect use as animal food is inefficient. A possible answer is to make bland extracts and restructure them into acceptable foods in such a way as cheese is made from milk, sausage from less attractive animal products.

The possibilities in chemical conversions are obvious. It is conceivable that in the future organisms can be selected primarily for their propagation characteristics, and the desired products obtained by biological modification added subsequently, as for example by transfer of a required gene from a completely unrelated source.

A population increase would require recapture of parks for agriculture; the population pressure for the "new" traditional recreational needs would make such recapture impossible. In multiple-use forests, a cycle of recreation-forest growth-harvestreforestation would allow continual recreation use with only temporary withdrawals that could be rotated.

For example, sugar beet growers abandon good rotation programs in order to maintain "history" of beet cropping at the irretrievable expense of building up nematode and root rot pathogen populations. Land tax increases in suburban areas are controlled by urban political interests forcing agriculture to abandon its land to the urban sprawl.

Our problems are substantially different from those in pumping crude oil from a well, or piping gas to a factory. Ultimately, there must be a good coordination of growth research, harvesting research and utilization research.

Though a necessary approach, it has caused many ecologists to lose patience and to forget the ultimate objective so that, in plant ecology in particular, the holistic view is something to which one pays lip service while in fact one is doing physiology. The open nature of territorial vegetation as an ecosystem, and the semantic difficulties created but not solved by pioneer plant ecologists, have contributed also to the present near-sterility of community ecology; hardly any first-rate minds now seem to be entering the field.

From page 125... ...
, some areas of wilderness must be preserved inviolate, as our ancestors handed them to us. Not the least important of these reasons is the archival function relatively undisturbed areas must perform for ecological research of the broadest sort imaginable -- including, for example, the relation of snowshoe hare population cycles to human cardiac disorders.
