An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
The current economic demand is not a cause for the increase in the leisure activities.
It causes a proportional increase in current.
Increase current by either increasing the voltage or decreasing the resistance.
more flooding (apex)
an increase of corporate profits

Plenty of food
an increase in current, hence increased power and increased heat.
An increase in biologic activity
Wind speed affects the electrical output of windmills. Strong sustained winds often produce higher electrical outputs. In the United States, all major electrical grids operate on alternating current - so it is very likely that windmills produce AC power.
