Man probably could not live without

Man probably could not live without the help of animals. The role of animals in the balance of nature ranks as their most important service to man.
Animals also serve man by supplying him with many food and other useful products. without animals, man would have no meat, milk, eggs, or honey; or wool, fur, or silk.
For thousands of years, man has caused changes in the animal kingdom. He has tamed many kinds of animals and used them for food and clothing. He has killed or driven away animals that once attacked him or interfered with his use of land. Today, he tries to protect many kinds of animals that are in danger of dying out.
Like man, most plants depend on animals for many of their basic needs. Without animals, many plants could not easily reproduce. For example, many plants with flowers depend on bees and other insects carry their pollen from plant to plant. Many oak trees grow from acorns that squirrels bury and then forget, or from acorns that deer step on and push deep into the soil. Birds often fly from one place to another with seeds clinging to their feet. The seeds may sprout a great distance from the parents plants.
