Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Also Humans may destroy natural landscapes as they mine resources and urbanize areas. This is detrimental, as it displaces residing species, reducing available habitats and food sources. ... This can negatively effect an ecosystem because the introduced species may outcompete native organisms and displace them.
