A forest science program provides important knowledge regarding the value of forests and how these areas are pivotal to global ecosystems. Individuals who study forest sciences learn about the growth and development of forests, the climatology of woodlands and factors that influence the health of forests.

Spain, officially the Kingdom of Spain, is a sovereign state and a member state of the European Union. It is located on the Iberian Peninsula in southwestern Europe. Spanish universities regulate access to their own degrees and they fix the academic fees. They can also offer unofficial postgraduate degrees. The capital city Madrid has possibly the largest number of bars per capita of any European city and a very active nightlife.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
