Why is a forest considered a valuable ecosystem service?

• Services (like absorbing CO₂, providing habitats...) are worth more than the wood products made from cutting them down

• The $ from wood products made from cutting them down is worth more than the services (like absorbing CO₂, providing habitats...)

• Forests do not provide any ecosystem services

• Forests provide an equal value regarding the services they provide and the $ that can be made from selling the wood from cut down trees
