Step 1: Understanding the Question:
The question requires validating two basic ecological principles regarding the environmental impact of forest ecosystems.
Step 2: Detailed Explanation:
• Climate Change Mitigation (Statement I): As established in Question 107, forests act as significant carbon sinks. By sequestering atmospheric \(CO_2\), they directly address the cause of global warming. Therefore, they are a primary tool for mitigation of climate change. Statement I is correct.
• Microclimate Regulation (Statement II): Forests significantly alter the physical environment within and immediately around them. This is called the "microclimate." Forests:
- Reduce temperature extremes (cooler in day, warmer at night).
- Increase relative humidity through evapotranspiration.
- Reduce wind speed.
- Influence local rainfall patterns through the recycling of water vapor.
Therefore, Statement II is correct.
Step 3: Final Answer:
Both statements are fundamental and correct truths in forest ecology.
