How do global issues related to population and resources reflect changes over the past 50 years

There have been change in the past 50 years that have profoundly impacted sustainability.  Global issues.  The global impacts of large-scale industrialization and materialism.  Population growth and increased life expectancy, especially in development of the world.  Globalization of trade and transport.  Impacts of science and technology exponentiation.  Increased corporate influence in relation to government and private citizens.

Explanation:

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
