Which of the following anticipated changes is not directly associated with the greenhouse effect ?

Options

A. Global shift in climate
B. Depletion of ozone layer
C. Rise in sea level
D. Extinction of some forms of wildlife

Answer

To determine which anticipated change is not directly associated with the greenhouse effect, we can analyze each option provided:

1. **Global Shift in Climate**: The greenhouse effect contributes to global warming, which leads to changes in climate patterns. Therefore, a global shift in climate is directly associated with the greenhouse effect.

2. **Depletion of Ozone Layer**: The depletion of the ozone layer is primarily caused by human-made chemicals like chlorofluorocarbons (CFCs) and is not directly related to greenhouse gases. Hence, this change is not directly associated with the greenhouse effect.

3. **Rise in Sea Level**: The greenhouse effect leads to global warming, which causes polar ice to melt and contributes to rising sea levels. Thus, this change is directly associated with the greenhouse effect.

4. **Extinction of Some Forms of Wildlife**: While the greenhouse effect and climate change can lead to habitat loss and extinction of species, this is an indirect effect. The extinction of wildlife is not a direct consequence of the greenhouse effect itself.

Based on this analysis, the anticipated change that is not directly associated with the greenhouse effect is:

**Answer: Depletion of Ozone Layer (Option B)**
