Economy & Systems & Capital & Resources & so on...

The different economic systems around the world have several similarities, the main one is that they produce and distribute goods and services by using natural, human and manufactured resources to satisfy people's needs and wants in the must effective and efficient way. 



As any system, the economic systems need inputs (resources) and produce outputs (goods and services). The resources for economic systems are called capital, and this capital is classified in 3 types:

• natural capital- natural resources that have a big value and help in supporting life.  It includes tangible natural resources (like trees), and processes (like biogeochimical cycle)
• human capital- the workforce of humans that manufacture those resources
• manufactured capital- some other goods produced in a previous stage of production, which are the raw material of other businesses.

From those three, the one we're focusing more is the natural capital, because it yields natural income. One evidence of the importance of natural capital is that the World Bank calculates a country's wealth by also considering the way it administers its natural resources, along with the other criteria.

This natural capital can be divided in 4 main types:

• Renweable
• Non-renewable
• Replenishable
• Recyclable

We've learned that  replenishable resources have characteristics between renewable and non-renewable, but it depends on how much time it takes to regenerate.
