1. Russia:

Russia is nearly twice the size of Canada. Its sheer scale allows it to be a dominant energy superpower.

  • Natural Wealth: Holds the world’s largest reserves of natural gas and 20% of global forest cover.
  • Geographical Fact: Lake Baikal in Russia is the deepest freshwater lake, containing 20% of the world’s unfrozen surface freshwater.

2. Canada:

Canada is unique for its massive freshwater reserves and maritime extent.

  • Freshwater: It contains more lakes than the rest of the world combined.
  • Strategic Growth: Despite its size, it has a very low population density, with most people living near the US border.

3. China:

China’s geography is highly varied, ranging from the Tibetan Plateau to the Gobi Desert.

  • Borders: It shares the most international land borders (14), a crucial point for International Relations studies.
  • Economy: As the world’s leading manufacturer, its geography facilitates massive trade through its eastern coastline.

4. United States:

The US has a highly productive landscape that supports the world’s largest economy.

  • Agriculture: The vast Central Plains make the US a leading global food exporter.
  • Regions: Includes non-contiguous states like Alaska (its largest state) and Hawaii.

5. Brazil:

Brazil’s geography is synonymous with environmental stability.

  • Biodiversity: The Amazon Basin is vital for the global carbon cycle and houses 10% of known species.
  • Agriculture: It is a global leader in coffee, soy, and sugarcane production due to its tropical climate.

6. Australia:

Australia is the largest country in Oceania and the 6th largest globally. It is unique because its territory covers an entire continent.

  • Geographical Features: It is predominantly semi-arid, with the Great Dividing Range in the east and the Great Barrier Reef (the world’s largest coral reef system) off the northeast coast.
  • Resources: Australia is a global leader in mineral exports, particularly iron ore, coal, and lithium, making it a key trade partner for India’s industrial growth.
  • Ecosystem: Known for its high rate of endemism, meaning many of its species (like Kangaroos and Koalas) are found nowhere else on Earth.

7. India:

India is the 7th largest country by area but holds the #1 rank in population as of 2026.

  • Geographic Diversity: Spans from the Himalayas (young fold mountains) in the north to the tropical Indian Ocean in the south.
  • Strategic Location: India sits at the heart of the Indian Ocean Region (IOR), controlling major Sea Lines of Communication (SLOCs).
  • Demographics: With 47 billion people, India has the largest workforce globally, which is a major driver of its status as the world’s 5th largest economy.

Global Significance of Large Territories

  1. Climate Regulation: Russia’s Taiga and Brazil’s Amazon are the world’s primary carbon sinks.
  2. Resource Security: Large countries often control critical minerals (Canada), energy (Russia), and food supplies (USA/Brazil).
  3. Geopolitical Leverage: Size provides “strategic depth,” making these nations central to global trade corridors like the IMEEC or INSTC.
