Ecological impact refers to the effect that human activities and natural events have on the environment and living organisms. This can include changes in habitats, pollution, and the loss of biodiversity. For example, when forests are cut down for agriculture, it can lead to the destruction of homes for many species, including birds and small mammals. Additionally, the use of chemicals in farming can contaminate soil and water, harming both plants and animals. Understanding ecological impact is crucial for developing sustainable practices that protect our planet and ensure that future generations can enjoy a healthy environment.
