Natural Resources: Air and Water

• Natural resources are materials or substances that occur in nature and can be used for economic gain
• They are essential for human survival and development, providing for basic needs like food, water, shelter, and energy

Four Types of Natural Resources

• Natural resources can be categorized into four main types based on their origin and renewability:
  • Air
  • Water
  • Land
  • Minerals

Air Resources

• Air is a mixture of gases that forms the Earth's atmosphere, essential for life
• Examples:
  • Oxygen: Necessary for respiration in most living organisms
  • Nitrogen: An important component of proteins and DNA, also used in fertilizers
  • Carbon dioxide: Used by plants for photosynthesis
  • Wind: Moving air harnessed for energy generation through wind turbines
  • Atmospheric pressure: Utilized in certain industrial processes and weather forecasting

Water Resources

• Water is a vital resource covering about 71% of the Earth's surface
• It is essential for drinking, agriculture, industry, and supporting ecosystems
• Examples:
  • Rivers: Provide fresh water for consumption, irrigation, and transportation
  • Lakes: Serve as reservoirs for drinking water, recreation, and support aquatic life
  • Groundwater: Water stored beneath the Earth's surface, used for drinking and irrigation
  • Oceans: Provide a source of food, transportation routes, and potential energy
  • Glaciers: Store large amounts of fresh water, contributing to river flow when they melt

Land Resources

• Land refers to the Earth's solid surface, including soil, rocks, and vegetation
• It is used for agriculture, forestry, construction, and habitation
• Examples:
  • Soil: The upper layer of the Earth's crust, supporting plant growth and agriculture
  • Forests: Provide timber, regulate water cycles, and support biodiversity
  • Grasslands: Used for grazing livestock and wildlife habitat
  • Arable land: Land suitable for cultivation of crops
  • Wetlands: Areas saturated with water, supporting unique ecosystems and providing flood control

Mineral Resources

• Minerals are naturally occurring, inorganic solids with a specific chemical composition and crystal structure
• They are extracted from the Earth's crust and used in various industries
• Examples:
  • Iron ore: Used to produce iron and steel for construction, manufacturing, and transportation
  • Coal: A fossil fuel used for electricity generation and industrial processes
  • Petroleum: A fossil fuel refined into gasoline, diesel, and other fuels for transportation and heating
  • Gold: A precious metal used in jewelry, electronics, and as a store of value
  • Limestone: Used in the production of cement, building materials, and agriculture

Environmental Care as a Student

• As a student, there are many ways to care for the environment

• These actions, though seemingly small, can collectively make a significant positive impact

• Reduce, reuse, and recycle:

  • Minimize waste by reducing consumption, reusing items whenever possible, and recycling materials like paper, plastic, and glass

• Conserve energy:

  • Turn off lights and electronic devices when not in use
  • Use energy-efficient appliances and light bulbs
  • Walk, bike, or use public transportation instead of driving whenever possible

• Save water:

  • Take shorter showers
  • Fix leaky faucets and toilets
  • Use water-efficient appliances
  • Water plants efficiently

• Reduce pollution:

  • Avoid using single-use plastics
  • Dispose of waste properly
  • Support local initiatives

• Advocate for sustainability:

  • Educate others about environmental issues and encourage them to take action
  • Participate in environmental campaigns and initiatives
  • Support businesses and organizations that are committed to sustainability

• Practice responsible consumption:

  • Choose products that are environmentally friendly and ethically sourced
  • Avoid products that are harmful to the environment or human health
  • Support local and sustainable agriculture

• Conserve biodiversity:

  • Respect wildlife and their habitats
  • Avoid disturbing natural areas
  • Support conservation efforts

• Plant trees:

  • Participate in tree-planting events
  • Plant trees in your own backyard or community
  • Support organizations that plant trees

• Be mindful of your impact

  • Consider the environmental impact of your actions
  • Strive to make choices that are sustainable and responsible

• Get involved in environmental clubs and organizations:

  • Join environmental clubs or organizations at your school or in your community
  • Participate in environmental activities and events
  • Learn more about environmental issues and how you can make a difference
