Study Notes

Plant Resources

  • 13,500 species of plants serve as foods, construction materials, raw materials, and ornaments.
  • Forests provide timber and logs for furniture and construction materials.
  • Rattan and bamboo are ideal for handicrafts and furniture.
  • Wild orchids, ferns, and other plants are sold as ornamental plants or bred to produce commercial varieties.

Mineral Resources

  • Minerals are naturally occurring, inorganic elements or compounds in solid, crystalline form.
  • The Philippines is rich in metallic minerals such as nickel, cobalt, silver, gold, zinc, iron, and copper ores.
  • The country's metal deposits are estimated at 21.5 billion metric tons.
  • Nonmetal deposits in the Philippines include clay, limestone, marble, guano, asphalt, feldspar, sulfur, talc, silicon, and phosphate.

Aquatic and Marine Resources

  • Corals are important to the health of reef ecosystems due to their symbiotic relationship with photosynthetic algae called zooxanthellae.
  • Aquatic and marine resources can be protected and conserved by:
    • Avoiding products made from sea organisms.
    • Supporting organizations that protect the ocean and the environment.
    • Participating in coastal cleanup activities.
    • Supporting fishermen's awareness of regulating fishing seasons and preventing overfishing.
    • Refraining from using plastics.
    • Using reusable containers and bags.
    • Learning how to recycle.
    • Helping to clean up the beach after swimming, surfing, and diving.

Forest and Agricultural Resources

  • The Philippines' forests are being depleted at an alarming rate, with an estimated loss of 1500 square kilometers from 2002 to 2020.
  • Mangroves are vital parts of coastal ecosystems, serving as breeding grounds for fish and other aquatic organisms.
  • Mangroves provide organic nutrients for marine life and help stabilize shorelines and lessen the effects of typhoons.
  • Many mangrove forests have been destroyed by human activities, with some areas converted for aquaculture practices.

Explore the diverse ecosystems in the Philippines' coastal areas, including coral reefs, mangroves, and seagrass beds. Learn about the importance of mangroves as breeding grounds for aquatic organisms and their role in coastal ecosystems.
