Part B

Read this excerpt from "Improving Old MacDonald's Farm."

In some cases farmers use animal waste as fertilizer, and even though it’s natural, if used incorrectly it can do terrible damage to water resources. In fact, it can cause eutrophication, or algae buildup, which depletes the oxygen aquatic organisms need to breathe.

The bad news is that erasing these forms of pollution entirely is practically impossible. The good news is that there are steps farmers and ranchers can take to reduce the amount of pollution that comes from farms and ranches. For starters, they can reduce the amount of soil erosion and sedimentation by 20 to 90 percent by using soil conservation practices. One way to keep the soil in place is to make sure as much soil as possible has something growing in it or placed on it (like mulch). Plants and their roots help anchor the soil, keeping it in its place.

How does the structure identified in Part A contribute to the development of ideas in this section of the article?


The first paragraph discusses animal waste, and the second paragraph contrasts animal waste with sedimentation.

The first paragraph discusses the issue of agricultural pollution, and the second paragraph explains resolutions to that problem.

The first paragraph explains the cause of animal waste pollution, and the second paragraph explains how it promotes soil erosion.

The first paragraph states that animal waste is the worst cause of pollution on farms, and the second paragraph suggests that sedimentation is less damaging.

What is "problem and solution" structure?

It is a structure where at first an issue is discussed and then solutions are given to solve the related problem.

What is agricultural pollution?

"Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests."

Incomplete question.

Here is the missing "Part A" excerpt from "Improving Old McDonald's Farm".

One important source of water pollution caused by farming activities is called sedimentation. Sedimentation occurs when wind or water runoff carries soil particles and dumps them into a nearby lake or stream. Too much sediment can cloud the water, which reduces the amount of sunlight that reaches aquatic plants. It can also clog the gills of fish or smother fish larvae. Another source of pollution is animal waste. By keeping animals such as hogs and cattle within certain small areas or lots, farmers can feed and care for those animals more easily than if they were allowed to roam unchecked. However, these small areas can become overloaded with animal waste—very overloaded. Check out these manure totals in the United

States in 1999:

• Beef cows – 624 billion pounds

• Dairy cows – 409 billion pounds

• Hogs – 242 billion pounds

• Poultry – 146 billion pounds

Added together, these animals produced nearly one billion tons of waste in just one year! Runoff can carry this waste into nearby lakes or streams, bringing with it dangerous bacteria and viruses if heavy storms come through or if the waste systems break down. When Hurricane Fran flooded much of eastern North Carolina in 1999, some waste lagoons burst, sending tons of animal waste into areas inhabited by people and into water sources used by people. It’s not just animals, though. Chemicals in pesticides, herbicides, fungicides, and fertilizers are a third cause of water pollution. Pesticides, herbicides, and fungicides are used to kill pests such as crop-eating insects and to control the growth of weeds and fungi. Fertilizers are used to feed crops and make them grow faster and healthier. Unfortunately, chemicals used to kill bugs and weeds can also damage other things. These chemicals can enter and contaminate water in several ways—through use and overuse in or around the water, from runoff, or by the wind. And their effects can be deadly. The chemicals can kill fish and other wildlife, poison food sources, and destroy the habitat that small animals use to hide from predators.

The author used the problem and solution structure to organize information in "Improving Old MacDonald's Farm" as at first he described the problem of agricultural pollution and then proposed the solutions in the next part.

The structure "problem and solution" identified in part A contribute to the development of ideas in part B of the article because in the part A the author delineated all the problems related to agricultural pollution, and then in Part B he proposed some solutions to solve the issue related to the problem.
