Clearcutting is

When logging companies plant new saplings in an area bigger than 1 hectare.
A timber harvesting practice where all of the trees in a given area are harvested at the same time.
When forestry services clear out the underbrush in a given area.
All the clearcutting facts below are true. Which are benefits or pros of clearcutting?
Clearcutting generates more consistent and higher rates of return for the logging companies and its investors

has no affect on the environment.
releases carbon dioxide and contributes to climate change.
is beneficial to ecosystems and animal habitats.
reduces flooding and erosion.
