• List of Human Activities and its effects to Natural Resources

  • Use of Plastic
  • Emission of Carbon Dioxide and other Greenhouse Gases
  • Overhunting and overfishing
  • Logging
  • Use of Chemical Fertilizers
  • Water Pollution
  • Mining and Quarrying
• Use of Plastic


  Waste plastic is everywhere on earth, even in the oceans. The chemicals present in the plastics are released in the waters. Wildlife is most affected, and some have even died after consuming unusually great amounts of plastics.
• Emission of Carbon Dioxide and other Greenhouse Gases

  Hydrofluorocarbons (HFCs) and methane are human-induced through the combustion of fossil fuels and the use of man-made products.
• Emission of Carbon Dioxide and other Greenhouse Gases

  Global temperatures cause sea-level rise and extreme weather events like heatwaves, flooding, tsunamis, and droughts.
• Burning of fossil fuels

  Increases the amount of carbon dioxide in the atmosphere and leads to depletion of atmosphere and fuel sources.
• Overhunting and overfishing


  Overhunting and overfishing have caused a reduction in the diversity of plant and animal species on earth. Overfishing threatened many marine species and may lead to extinction. When too many fish are taken out from the ocean it creates an imbalance and lead to a loss of other important marine life.
• It usually takes a long time to recover from the damage caused by overhunting and overfishing.
• Animals are often hunted for their valuable skins, plumage, horns, and meat.
• Overhunting and overfishing do not give chance for the organisms to grow and develop.
• Logging


  Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Trees are being cut down for timber to make furniture and paper and paper products.
• Logging practices


  May result in deforestation and increases the possibility for flooding due to soil erosion. Some living organisms lose their habitats and migrate to other areas, affecting the balance of local populations.
• Use of Chemical Fertilizers


  The injection of vast amounts of phosphorous and nitrogen nutrients into natural soils, land, and water systems due to fertilizer use. The use of too much chemical fertilizers may destroy the quality of soil. The toxicity of chemicals brought by using chemical fertilizers may harm the lives of both humans and other living organisms.
• Water Pollution


  Nitrates from organic fertilizers, phosphates from detergents, organic wastes and solid wastes are the main pollutants of freshwater. Nitrates and phosphates accumulate and cause eutrophication. Eutrophication decreases the amount of oxygen present in the water. Marine waters are usually polluted by oil spills from oil rigs from ships during transfer across the sea. The oil can be harmful to plant and animal life in the waters.
• Mining


  Mining involves taking an economically useful material from the ground. Substances that are mined include ores, coal, evaporites, and precious stones and metals.
• Quarrying


  Quarrying is the cutting or digging of stone, and related materials, from an excavation site or pit and it usually leaves behind a large hole in the ground.
