Conservationists argue that watershed protection and other ecological functions of forests are more economically valuable than timber. Timber companies argue that continued production supports stable jobs and local economies. If you were a judge attempting to decide which group was right, what evidence would you need on both sides?

it is true
If I were the judge and had to decide witch group was right I would first need to survey several members of that particular community on how it affects them either way. Then I would gather all the revenue information and how many jobs were created and compare itto how removal of timber would impact the area. After having all the information I gathered I would then be able to make an educated decision
