Building dams, deforestation (cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads are all examples of how humans negatively affect local ecosystems.

These activities can disrupt natural habitats, alter water flow, contribute to pollution, and fragment landscapes, which can harm local flora and fauna and disrupt ecological balances.
