Ecological Impact is the effects left on organisms and their environment due to actions made by humans and natural occurrences. These changes can be beneficial or adverse to the ecosystem.

An example of ecological impact can be seen in the case of invasive species. While these organisms are brought into the ecosystem by humans to help solve a problem or are introduced by accident; they can pose a threat to the environment due to there being no predator to keep the invasive species under control. This can have a severe impact on the ecosystem by allowing the invader to continue to grow in number and force out native species from the environment.
