what are some examples of how we interfere with ecosystems. For each example, explain how it happens, why we do it, and then mention short and long term effects of it

We cut down trees in the ecosystem for wood or to make buildings. This kills animals because they no longer have their habitat. Short term effects would be less trees because we can always plant more and a long term is extinction of animals because of habitat loss. Another example is pollution.We drive cars and buses that produce a lot of pollution. We do this to get from point a to point b, a short term affect would be  pollution in the air, a long term is ruining the earths o-zone which let in radiation.
