Assignment

One of your first clients is a restaurant owner whose kitchen has become infested with cockroaches. Identify and describe one negative health risk posed by cockroaches to the restaurant's customers. Identify two possible sources of the cockroach infestation, and describe an appropriate prevention strategy that targets each source.

You meet a farmer whose crops are being eaten by aphids. The farmer has been using an organic phosphate-based insecticide to control his pest problem. Describe one potential negative effect to the environment and one potential negative effect to human health caused by using organic phosphates. Identify and describe two integrated pest management (IPM) practices that the farmer could use instead of organic phosphates to control his aphid problem.

The farmer with the aphid problem asks you how IPM might affect him financially. Answer his question by explaining the concept of a pesticide treadmill.

Identify and describe one additional economic cost and one additional economic benefit, other than those discussed in Part (c), that the farmer is likely to derive from the IPM system you recommended in Part (b)

A salmon farm has seen its sales decrease by an average of 4 percent per year from a high of 15 million pounds in 2007. During the same period, it has increased its prices by an average of 6 percent per year from $1.50 per pound in 2007.

Determine how many pounds of salmon the farm sold in 2009. Then calculate the difference between dollars earned from sales in 2009 and dollars earned from sales in 2007. Round your figures to the nearest cent.

Calculate the minimum number of pounds of salmon the farm would need to sell at 2007 prices to match its 2009 earnings. Round your answer to the nearest pound. Explain how government subsidies could help the farm become more profitable.

Using salmon as an example, explain the difference between bioaccumulation and biomagnification. Explain how aquaculture can reduce the risks posed by these phenomena to people who eat fish.

Identify and describe one environmental advantage and one economic advantage, other than those discussed in Part (c), of farming salmon rather than catching them in the wild. Identify and describe one environmental disadvantage and one economic disadvantage, other than those discussed in Part (c), of farming salmon rather than catching them in the wild.
