Climate change, primarily a water crisis.
Climate change is disrupting weather patterns, leading to extreme weather events, unpredictable water availability, worsening water scarcity, and contaminating water supplies. Moreover, increasing global temperatures cause water to evaporate and hence more frequent, heavy, and intense rains in the coming years. This will lead to more foods since more water will fall than vegetation and soil can absorb. The remaining water, or runoff, drains into nearby waterways, picking up contaminants like fertilizer on the way. Excess runoff eventually travels to larger bodies of water like lakes, estuaries, and the ocean, polluting the water supply and limiting water access for humans and ecosystems.
