Land to sea ratio
The land to sea ratio on earth is constantly changing.
Currently, land occupies about 28.9% of the earth.
That is, the land-to-sea ratio is typically 29:71.
However, it is not possible to easily derive this value by simply looking at the world map and calculating.
The boundary between land and sea is very vague, so you need to carefully examine the following factors.
- Transportation network
- Population distribution
Generally, the number calculated in consideration of the above factors is 29:71, but it is strictly fluctuating.
