Globalisation
Although on the whole globalisation could be seen as a good thing because cultures are mixing and learning about each other. However the reality is that American own a large proportion of the world's media and they mediate their images into other cultures which causes for confusion and mixed messages on the dominant ideologies in cultures of what is seen as beautiful, success for example. This also means that a lot of cultures that are not American or Western/ originate from Europe can be ignored and pushed aside with the main representations of people being that of western ideologies.
As mentioned above, media tend to split the world into what they see as important and what they want to portray. Other cultures are destroyed or simply ignored as they are not seen to contribute to what the US media would argue is important coverage.
A small proportion of the worlds population own any power in the images which are reproduced and delivered to us. For example Rupert Murdoch owns much of the worlds tv and media:
Sustainability now is used a way to sell products to individuals as they are packages as being "green" as more people are now concerned with the environment. Companies are creating products which make people feel as though they are doing good, but they also in turn just end up being litter too.
