问题是：以下这段阅读是否说明
Human factors can intensify or alter the effects of climate change on landsliding activity.
答案显示passage的确说明了上面那点，但我真的看不出来。我认为passage只说了human activity可以intensify landslide，而不是intensify effects of climate change on landslide。谢谢帮助

原文如下：

There is mounting evidence that the frequency and magnitude of landsliding is changing in many parts of the world in response to climate change. This is not surprising, given that precipitation is one of the two external triggering mechanisms—the other being seismic activity—involved in the formation of landslides. Evidence from the past clearly indicates that cycles of elevated landslide activity have been followed by cycles of low activity, and that these are correlated with climate fluctuations over a variety of timescales.

What sets current changes in landslide activity apart is the likely influence of anthropogenic [i.e., human-caused] factors, either acting alone or in concert with climate, which can further modify the process of landsliding and the nature of ecosystem responses. Among these factors, deforestation and land-use change have the potential to influence the frequency and magnitude of landsliding because of their direct effects on vegetation attributes that influence slope stability. The extent and conditions under which mountain ecosystems are resilient to these changes—that is, the amount of disturbance they can absorb before changing into states with different structure and function—are not known. Addressing this issue is crucial for the long-term conservation of mountains capes.

我跟你有一样的疑惑，文中只能说明人类活动单独可以影响landsliding activity 或者与climate一起协作影响 landsliding activity，人类活动怎么能改变气候变化对滑坡活动的影响呢？
