Which statement best characterizes the effect of human events on the environment? 

A)  Feedback is usually immediate. 
B)  It is predicted that the environment is diverse. 
C)  Long delays exist between events and responses. 
D)  Our generalizations are based upon many experiences.

Human events can have long-lasting impacts on the environment, and it often takes time to see the full effect of those events on ecosystems and natural resources. For example, deforestation can lead to soil erosion and loss of biodiversity, but those effects may not become apparent for years or even decades after the initial clearing of trees. Similarly, pollution from industrial activities can take time to accumulate and begin to affect local water and air quality. Therefore, long delays exist between events and responses, and it can be difficult to predict the full extent of those responses.
