Lecture Notes: Changes in World Map if Sea Levels Drop by 1,000 Meters

Introduction

  • Familiarity with Maps: Most people recognize the traditional 2D world map.
  • Altered Perceptions: North Korea reportedly sees the world with itself at the center.
  • Effect of Removing Countries: Minor changes make the map seem unusual.

Hypothetical Scenario: Sea Level Drop by 1,000 Meters

  • Major Global Changes: Reveals underwater formations, creates new land.
  • Impact on Countries:
    • Islands connect, countries expand.
    • Coastal and low-lying areas gain land.

Effects on Specific Regions

Oceania

  • Australia:
    • Merges with Indonesia, forming a new landmass.
    • Tasmania merges with mainland.
    • Estimated land increase by 10-20%.
  • New Zealand:
    • North and South islands merge.
    • Unrecognizable shape.

Southeast Asia

  • Land Connectivity:
    • Sumatra, Java, Borneo, and the Philippines connect to mainland.
    • Vietnam and Thailand remain largely the same.
  • East Asia:
    • Japan connects with Russia and China.
    • South Korea becomes landlocked.
    • Taiwan joins China physically.

South Asia

  • Bangladesh and Maldives: Gain significant land, solving rising sea level issues.
  • Sri Lanka: Connects to India, potential economic boost.

Central and Northern Asia

  • No Changes: Landlocked countries like Bhutan, Nepal, and Central Asian "-stans".
  • Russia: Gains land towards the Arctic, potential economic benefits.

Africa

  • Mainland Africa: Slightly larger, no significant changes.
  • Islands:
    • Madagascar and Seychelles grow notably.
    • Yemen connects to Africa via Eritrea and Djibouti.
  • Red Sea Scenario: Turned into a lake.

Middle East

Polar and Remote Regions

  • French Southern Territories and Heard & McDonald Islands: Merge into larger land masses.

Europe

  • Dramatic Changes:
    • Entire continent merges into a single landmass.
    • UK connects to Ireland and the mainland.
    • New region 'Doggerland' reemerges.
  • Continental Bridges:
    • Iceland to Greenland, and Greenland to Canada.
    • Europe connects to North America.

North America

  • United States: East coasts broaden, Florida connects to the Bahamas and Cuba.
  • Mexico: Similar changes to the US.
  • Canada: Size potentially doubles, Hudson Bay disappears.

South America

  • Argentina: Sees noticeable growth.
  • Falkland Islands: Merge with Argentina.

Conclusion

  • Most Changed Countries: Possibly New Zealand, Norway, and the UK.
  • Encouragement for Viewer Engagement: Prompt to comment on the most changed country.
