How do you feed millions of humans and meet their nutritional needs without destroying the planet with greenhouse gases? The World Wildlife Federation has released data on one of the primary sources of food for more than six billion people worldwide – milk. The average person in the United States consumed 643 pounds (292 kg) of dairy products in 2017, including milk, butter, cheese, yogurt, and ice cream. Those foods came from 9.3 million dairy cows, but there are 278 million in the world. Milk production has grown by 30% from 2005 to 2015, and that comes to 909 million tons. India is the leading producer with 20% of the world’s supply. The U.S. has 12%.
The design of cattle that can produce that much milk was recognized in prehistoric times, and cattle were worshiped because they provided so much food for humans. Skeptics would respond that the environmental impact of cattle is so huge that it is a bad design. It does take 144 gallons of water to produce one gallon of milk in the U.S., with over 93% of it involved in growing feed for the cattle. The average dairy cow will eat 100 pounds of feed, and 9% of American cropland is used to grow feed crops for dairy cows. A cow will produce 17 gallons of urine and manure, which can pollute rivers and lakes, and they generate greenhouse gases.
The fact is that only 2% of the total U.S. emission of greenhouse gases comes from milk production. The Northern Great Plains cover 180 million acres in Montana, Nebraska, North Dakota, South Dakota, Wyoming, Alberta, and Saskatchewan. The land became rich in resources and healthy when grazing animals such as bison aerated and fertilized the soil. With the past numbers of those animals gone, scientists now say that something else must fill that niche or erosion will increase, and invasive plants will take over. Studies by the World Wildlife Federation show that cattle production areas in the Northern Great Plains have lower per acre emissions than row crop agriculture such as corn, soybeans, and wheat. The most recent study shows “done right, ranching can help conserve biodiversity while minimizing its own environmental footprint.”
Like everything else that God has given us, milk production must be managed carefully and with a concern about “taking care of the garden, dressing and keeping it” (Genesis 2:15). Milk is one of God’s great blessings, and a land “flowing with milk and honey” is held out as the most favorable place to live.

We are frequently astounded by what animals can do. As science seeks solutions to problems such as having enough food, knowing how to avoid disasters, and solving medical problems, we frequently see the answers in the designed features of living things. There are many things we can learn from the animals.
How can we have enough food to feed everyone on this planet? One way is to take advantage of animals with high reproductive capacity. A female mackerel, for example, lays about 500,000 eggs at one time. We have relied on animals like cattle which have one offspring at a time, are environmentally unfriendly, and require massive energy to sustain. Many fish, arthropods and mollusks can reproduce massive numbers of offspring, need very little energy input, and give off little or no environmental hazards. Some of them even remove environmentally unfriendly materials.
Can we improve our vision and perhaps restore sight to people who are blind? Studies of the common dragonfly have shown that each eye has 30,000 lenses. Our one lens is limited as to what we can see. The way images are transmitted to the brain in animals allows multiple transmissions. We are learning from insects and chameleons how the brain can reconstruct a useful image from many separate images. A chameleon can move its eyes in different directions, and its brain can interpret the direction and identification of what each eye is seeing independently.
How can we make stronger materials? Beaver’s teeth are so sharp that Native Americans used them as knife blades. The structure of the tooth enamel in the beaver and how the teeth maintain their sharpness is an area where materials science researchers can learn from the animals.
Can we make better drones? Researchers are interested in how high-frequency wing beats can allow better control of flight. Tiny flies known as midges beat their wings over 1000 times a second – twice as fast as mosquitoes. We can even learn from the animals that are almost too small to see.
Examples like these challenge those who would attribute animal design to chance processes and survival of the fittest. The design engineering in the animal world suggests wisdom beyond that of humans. In Proverbs 8:5,22,35 wisdom speaks, “O you simple ones understand wisdom and you foolish ones, have an understanding heart. The Lord possessed me (wisdom) in the beginning of His way, before His works of old. For whoever finds me finds life and shall obtain the favor of the Lord.” Let us be wise as we copy the wise designs of the Creator.
