REDBREAST, or ROBIN REDBREAST,a familiar European warbler (Erithacus rube-cula), which by its familiar habits has endeared itself to children, and has caused it to be protected and welcomed more than any other bird. The red breast of the male is the distinguishing feature of the species, but the females have duller colors. In Great Britain the redbreast is a permanent resident, but in more northern countries it is migratory, flying southward in winter. It also occurs in Asia Minor and in North Africa. The nest is made of moss and leaves, and is lined internally with feathers. The eggs usually number five or six, and they are white, spotted with pale brown.
The past year was one of action rather than innovation with respect to natural resources. Perhaps its most distinguishing feature was an increased emphasis on environmental quality as opposed to the traditional conservationist's role of trying to preserve resources for the future. The dizzying advance of technology after 1945 had led to the tacit assumption that whatever became possible was therefore justified. This, with the attendant increase in human numbers that threatened the political self-reliance of the individual, posed a fundamental question: Would man become the master or the slave of his own inventions, with their awesome power to consume resources and change the environment? With the world linked by rapid transport and communication, this question had become a planetary one. |
