Natural and human-made events work together in complex ways to shape how ecosystems change over time. Understanding how they interact is very important in environmental science, especially when looking at how human actions affect the environment.

Natural Events
Natural occurrences like wildfires, floods, and storms can kickstart changes in ecosystems by making room for new plants and animals. These events often reset the ecosystem, giving pioneer species a chance to grow. For example, after a forest fire, sunlight can reach the ground. This helps herbaceous plants thrive, which eventually allows a mature forest to grow back over time.

Human-Made Changes
Human actions, such as cutting down trees, building cities, and causing pollution, can greatly change ecosystems. These disturbances may lead to broken-up habitats. For example, land cleared for farming might not recover in the same way as land affected by natural events, because the soil and types of species are disturbed.

How These Events Work Together
The way natural and human-made events interact can make changes in ecosystems more complicated. For instance, areas that humans have altered can be more vulnerable to natural events, resulting in surprising effects on the environment. Additionally, practices like controlled burns can imitate natural events, helping to boost the variety of plants and animals in an area.

Conclusion
In summary, the combination of natural events and human-made changes plays an important role in how ecosystems evolve. This affects the variety of species and the strength of ecosystems. Recognizing these interactions is crucial for creating effective conservation and management plans in a world that is changing quickly.
