Final answer:
The true statement about disasters is that they can be natural or human-made. Humans and the environment are interdependent, with human actions sometimes exacerbating the impact of natural disasters, as seen in increased vulnerability and infrastructure failure.
Step-by-step explanation:
The statement about disasters that is true is: a. They can be natural or human-made.
Disasters have long been a topic of both concern and study in human ecology, recognizing the interconnectedness of people and their environments. As human populations grow and we inhabit increasingly vulnerable areas, natural disasters become more impactful.
Additionally, when looking at past disasters, we know significant events like hurricanes, earthquakes, and tsunamis have had dramatic effects on human lives and infrastructure.
For conservationists, both natural disturbances like lightning and human-related disturbances such as pollution are of concern because they disrupt ecosystems. Engineers and scientists continually work on ways to better protect, predict, and respond to disasters.
Finally, it's vital to note the role of human actions in exacerbating the impacts of natural events, which can lead to more severe consequences such as infrastructure failure during earthquakes due to construction issues, as artist Weiwei highlighted.
