Explanation / Answer
Humans actins has an effect on the ecosystem, sometimes beneficial , sometimes neutral but most of times it shows harmful effect on ecosystem. Damage can be done by killing too many species. Like
Overhunting:
Predators like tiger, bears which always keep a check on the plants eating animals, their maintain balance in ecosystem such that all plants are not been gazed by these animals, when predeators are removed by humans these animals will over graze and cause a distrubtuion in the ecosystem.
Deforestion:
Humans uses plants in many ways, he utilizes wood for production of energy, for construction and many more, for sake of these uses humans cut down many forests rate of deforestation is keep on increasing leading to destruction of rain forests itself. This will result in degradation vegetative count, flooding, and environmental changes and many more.
BY introducing new species:
When an new animal or plant is introduced in new ecosystem, in most of the cases these new species wont able to survive since it has been adapted to other ecosystem, this new ecosystem could prove fatal, making it life span very short in new home. But when these new species get adapted to new ecosystem will prove to be problematic, it can lead to cause environmental harm, impact health of ecosystem and humans also.
