The correct answer is C.
The Greek colonization period took place between the 6th and 8th centuries BC, in the Mediterranean Sea and Black Sea regions. This demographic process was centrally desgined, and the metropolis made the decisions about how it should be conducted. Many of the Greek settlements became strong cities afterwards.
The main reason that triggered this colonisation, was the demographic explosion that had taken place and the scarcity of farms and their production which could not cope with the population expansion in some regions, and this caused the desire of finding new regions to establish themselves. The decision of establishing a colony in a certain location depended on its potential, first of all, the kind of raw materials that could be taken to the metropolis and also the type of final goods that could be produced afterwards. Colonies were a big source of wealth for the Greeks.
The problem starts already earlier:wildlife experts can only estimate the number of species in the world generally!
This is the case because there are simply too many species, and it takes time to documents them; because some areas (ocean bottom for example) are very hard to access and because sometimes it's hard to know whether we're talking about a new species or a variation within the same species.
so if we even don't know how many species there are, it's even harder to know how many are endangered.
