Human activities significantly impact marshes through urban development, agriculture, and pollution. Dredging and draining for land use disrupt natural water flow and habitats, while runoff from fertilizers and pesticides degrades water quality. Additionally, climate change and rising sea levels, driven by human actions, threaten marsh ecosystems by altering salinity and flooding patterns. Conservation efforts are essential to mitigate these impacts and preserve marsh biodiversity.
