Human–wildlife conflict has been defined by the World Wide Fund for Nature (WWF) in 2004 as "any interaction between humans and wildlife that results in negative impacts of human social, economic or cultural life, on the conservation of wildlife populations, or on the environment". [6]
Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.
Overall, the effects of climate change increase stress on ecosystems, and species unable to cope with the rapidly changing conditions will go extinct. [28] While modern climate change is caused by humans, past climate change events occurred naturally and have led to extinctions.
To humans, it feels like the apocalypse has suddenly arrived. According to the biannual Living Planet Report published Wednesday by the World Wildlife Fund (WWF), mammals, fish, birds, reptiles ...
Biodiversity loss has bad effects on the functioning of ecosystems. This in turn affects humans, [45] because affected ecosystems can no longer provide the same quality of ecosystem services, such as crop pollination, cleaning air and water, decomposing waste, and providing forest products as well as areas for recreation and tourism.

Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda. Natural vegetation along this coastal shoreline in North Carolina, US, is being used to reduce the effects of shoreline erosion while providing other benefits to the natural ecosystem and the human community.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
By 1500 AD, a mere 200 years after the first human settlements, ten species of the giant moa birds were driven to extinction by the Māori. This rapid extinction underscores the significant impact humans can have on native wildlife, especially in isolated ecosystems like New Zealand.
