Climate change significantly impacts both terrestrial and aquatic ecosystems. In terrestrial environments, it alters habitats, disrupts species interactions, and leads to habitat loss through extreme weather events. In aquatic systems, rising temperatures and changing precipitation patterns can lead to ocean acidification, altered species distributions, and disrupted food webs. Both ecosystems face challenges like invasive species and altered nutrient cycles. Overall, these changes threaten biodiversity, disrupt ecosystem functions, and can have profound effects on human communities that rely on these ecosystems for resources and livelihoods.
