Question

Explain how human impact can lead to succession in ecosystems.

Answer 1

Answer:

Ecological succession refers to the changes taken place in a forest over a particular period of time.

Succession is usually influenced by environmental factors such as water regimes, soil type, climate, vegetation history, and invasive species.  

Humans interventions affect all of the above-mentioned factors.

Human activities such as fragmentation of forests, clearing of forests for agricultural practices, construction of dams, civilization, logging et cetera drastically reduce the biodiversity of a forest.

This reduction of biodiversity forms the foundation for a secondary succession of a forest.

Answer 2

Human impact on ecosystems is mostly negative but i did think of one example where it isn't and that is when forest like in the mountains are purposely lit on fire so that after the trees can grow back more green and less dry. This is example of secondary succession by the way.
Anyways i hoped this was able to help you(;
