Human activity on land can have a profound influence on marine ecosystems. true or false?

True. Human activities such as agriculture, urban development, and industrialization can lead to runoff of pollutants, nutrients, and sediments into coastal waters, significantly impacting marine ecosystems. This can result in issues like eutrophication, habitat destruction, and altered species distributions. Additionally, activities like fishing and shipping further stress marine habitats, contributing to biodiversity loss and ecosystem degradation.
