Humans impact on the environment can be either positive or negative
In a positive way, humans are classified as animals and they breathe out carbon dioxide for plants use. Plants need carbon dioxide for survival
In a negative way, humans build houses and engage in industrialization activities. To do this, humans need to clear land. This involves the destruction of plants and forests. When there are no plants or trees, it leads to global warming and climate change which destroys the environment. Hope I helped. Have a nice day
