What term can be used to describe the relationship between two factors when they have the same trend over time, such as increasing global population and global copper production?
Why did the development of the Haber process allow the global population to increase?

Fertilisers became much more expensive than before
Why is it essential that the humans alive on Earth today do not use up all of the Earth's resources?
So that future generations of humans can meet their own needs
