Answer:
A major cause of the loss of culture globally is the globalization.
Explanation:
Cultural convergence; is not correct because this is a process where two or more cultures merge into one over time, but that is not on a global scale.
Trade agreements; is not correct because these agreements are based around the economy, cheaper production, larger profit, and increase of the market.
Urbanization; is not correct because it represents the increase of urban areas and reduction of rural ones, but this causes people from the rural areas to move in the urban ones so there isn't really any loss of culture.
Globalization; is correct because through this process it is only one culture that gets heavily promoted, the western culture, and because it is beneficial and attractive to the younger generations, they adopt it but also gradually put aside their own culture, contributing to gradual dying out of it.
