Visualizing The World’s Loss of Forests Since the Ice-Age
How much of Earth used to be covered by forests, and what portion is covered today?
The effects of deforestation on the climate are already being seen and felt, and these repercussions are expected to increase with time. That’s why more than 100 world leaders pledged to end and reverse deforestation by 2030 at the COP26 climate summit.
As today’s graphic using data from Our World in Data highlights, the world’s forests have been shrinking since the last ice age at an increasingly rapid pace.
Earth’s Surface Area: 10,000 Years Ago
To examine the deforestation situation properly, it helps to understand Earth’s total available surface area. After all, our world can feel massive when glancing at maps or globes. But of the roughly 51 billion hectares in total surface area on Earth, more than 70% is taken up by oceans.
What’s left is 14.9 billion hectares of land, not all of which is habitable. Here is how the land was allocated 10,000 years ago, after the last ice age and before the rise of human civilizations.
Uninhabitable land on Earth (10,000 years ago):
- Barren land (19% or 2.8bn ha)—Includes deserts, salt flats, exposed rocks, and dunes
- Glaciers (10% or 1.5bn ha)—The vast majority concentrated in Antarctica
Habitable land on Earth (10,000 years ago):
- Forest (57% or (Read more...)
