The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. Part A The following answers for the Causes and Consequences features are examples and are not intended to represent a comprehensive list. In addition, the sequence of items is not meant to connote relative importance. Sort the examples below into the appropriate bin. Think about which factors contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Cause: nutrient runoff from agricultural fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition Consequences: death of aquatic organisms that cannot escape economic losses for fisheries shifts in the marine food web Solutions: policies to promote no-till agriculture construction of wetlands to absorb nutrients reduction of fertilizer use to decrease nutrient pollution from farmsThe hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide.
