This enormous increase of population will create immense problems

The Japanese figures are the same as our own country in overall land—1.1 acres per person, but it is a very mountainous country with volcanoes, and so much less is cultivable. Less than a fifty of an acre—0.17 of an acre—is under cultivation. You see at once the tremendous land problem which there is in Japan.(

A lot of things are going to happen in the next fifty years. It is enormously important to increase the yield of grain plants and a great deal has happened through the work of the geneticists in the last few years. For instance, there has been an enormous world increase in the production of what Americans call corn due to the development of new strains. Throughout agriculture geneticists are improving plants to get higher yields

Our Disappearing Wildlife,Animal life first appeared on the earth about 400 million years ago. Through the passing millennia, thousands of animal species have come and gone. Until recently, this process was gradual, the result of changes in climate, in habitat, or in the genes of the animals themselves. But the tremendous expansion of modern civilization now threatens to upset this natural balance, putting unprecedented pressure On the survival of our wildlife.

This imbalance can be traced to many causes. Most arise in the ‘greed and poor planning of people. With each increase in our population, the wilderness areas where the animals live get smaller. The use of pesticides to control injurious insects also harms wild birds and animals. Water pollution kills fish in our rivers and oceans. Hunters have almost exterminated many of the larger animals like the big-horn sheep and the grizzly bear. As a result of this unrelenting pressure, our wildlife is disappearing at the rate of one species or subspecies per year.

Animals that kill other game for food are called predators. The predators include the wolf, mountain lion, fox, bobcat and bear. Attack against these animals began with the arrival of the first European settlers, who wished to protect their livestock. Yet every animal, including the predator, has its place in nature’s grand design. Predators help maintain the health of their prey species by eliminating the diseased, young, old, and injured. Predators like the mountain lion and the wolf help to keep the deer herds healthy. Their kill also provides food for scavengers that feed on carrion. Occasional loss of livestock must be weighed against the good these animals do in maintaining the balance of nature.

Overhunting an animal is an obvious form of extermination, but there are more subtle processes that often have the same fatal result. One of these is destruction of habitat. When fanners introduced sheep and cattle .to North America, the domestic animals competed with the wild animals for the available grazing land. Animals like the buffalo and the pronghorn antelope, which once roamed the plains in countless numbers, were either killed or pushed off the grasslands.
