What Is Necessity And What Is Luxury... Actually?

I then further out my main topic and choose a question that I want to focus on; that is:

"What is necessity and what is luxury?"

First of all, this question have it's relation with and how it affect the biodiversity through consumerism. From this, it questions that how much We consume and how much We demand over the things that are around us that keeps us going, a place to live, places to go and to be alive.

So, what IS necessity actually?

- It refers to what We need in everyday basis that we could not actually be un-attach from it. For example, a toothbrush that we know we all need one to clean our teeth everyday of our lives.

And what IS luxury?

- The state of giving great comfort and extravagant living as to what we want. An inessential and desirable things that We even perhaps dream of wanting that sense of luxury. For example, having yacht for having a cruise around the open sea.

From this, I then wanting to know what people might give me the answer if I ask this question and how many answers are commonly given out here for the students in Brunei at University of Brunei Darussalam...
