Which human action would help reduce global warming

A Use more fertilizers to increase production
B Eat less red meat so fewer cattle need to be raised
C Ride a bicycle rather than walk to school
D Clear more forest to produce more farmland

B Eat less red meat so fewer cattle need to be raised

Reducing the consumption of red meat can help decrease the demand for cattle farming, which is a major contributor to greenhouse gas emissions. This can help reduce global warming by reducing the amount of methane released into the atmosphere.
