Deforestation, urbanization, agriculture, and mining are all major causes of habitat loss.

Agricultural runoff is the primary source of water pollution, contributing to eutrophication and contamination with pesticides and fertilizers.

Carbon dioxide (CO₂) is the primary contributor to climate change, accounting for approximately 64% of global greenhouse gas emissions.

Invasive species can impact ecosystems through competition with native species, predation of native species, transmission of diseases to native species, and hybridization with native species.

Habitat loss can lead to loss of biodiversity, reduced water purification, increased soil erosion, and other threats to ecosystem services.

Vehicle emissions are the primary source of air pollution in urban areas, contributing to smog, acid rain, and respiratory problems.

Climate change can lead to coral bleaching, shifts in species distribution, increased frequency of extreme weather events, and other threats to ecosystem services.

Invasive species can alter ecosystem structure and function through competition with native species for resources, predation of native species, transmission of diseases to native species, and other mechanisms.

Pollution can lead to eutrophication of water bodies, acidification of oceans, smog formation, and other threats to ecosystem services.

Climate change impacts ecosystems through changes in temperature and precipitation patterns, sea level rise, ocean acidification, and other mechanisms.

Invasive species can displace native species, transmit diseases to native species, hybridize with native species, and pose other threats to ecosystem services.

Pollution can impact ecosystems through direct toxicity to organisms, alteration of habitat structure and function, disruption of ecosystem processes, and other mechanisms.
