Animals provide many benefits to humans, including food, materials, and assistance. Silk worms produce silk fibers, which are used to make bright and light fabrics for clothing and parachutes. Bees produce honey for food and wax for candles. Lac insects are used to make bangles, toys, and jewelry. Biological control uses predators, parasites, and pheromones to control pests. Marine protozoans and mollusk shells are sources of materials. Snakes control rat populations and their skins are used in accessories. Birds and fish are sources of meat. Mammals provide milk, help with agriculture and transportation. In summary, animals play an important economic and practical role for humans in many industries and applications.
