How oil and coal are made
The Carboniferous period laid down gigatons of hydrocarbons. When plants were compacted and buried for millions of years, they couldn’t decompose naturally.
Eventually, they became methane, coal and oil reserves all stored underground. As we unlock these reserves, they hold incalculable worth.
We harness their power and release into the atmosphere. After we use them, it becomes part of the short and long-term carbon cycle again.
From here, it takes millions of years to become a fossil fuel again or just several to take part in the photosynthesis of a plant.
