Human activities like agriculture, industry, and deforestation are negatively impacting ecosystems. Deforestation leads to soil erosion, flooding, desertification, and climate change as trees are removed. Overfishing is also harming marine ecosystems - some fish species' populations have declined drastically due to overfishing, and destructive fishing methods damage habitats like coral reefs. Conservation efforts are needed to protect natural resources and ecosystems.
