Environmental issues arise from agriculture, ranching, forestry, and fishing activities if not properly managed. Negative effects include deforestation from plowing new lands and overgrazing, soil depletion from overexploitation, pollution from improper pesticide use, overdrawing of aquifers, degradation of forests from overharvesting, and depletion of fishing grounds from excessive catches. Potential solutions involve using sustainable practices like organic farming, reforestation, regulated harvesting, and aquaculture to protect natural resources for future generations.
