She is one of many who have taken the vow of living below her means for a week to raise money for Live Below The Poverty Line, an initiative of the Global Poverty Project and The Oaktree Foundation.

In doing so, from yesterday, the 21-year-old has pledged to spend no more than $2 on food each day for five days [ending August 6].

Ms Hord says she hopes to raise $2500 for the project, which will fund educational programs for people living in remote parts of Cambodia.

The final year student of musicology at the Sydney Conservatorium of Music said it was important to raise awareness about the estimated 1.4 billion people around the world who are living in extreme poverty, forced to survive on as little as $2 a day.

Ms Hord said she would live on items including eggs, bread, pasta, carrots and oats.

``The project gives us 1.4 billion reasons to start making a change against food wastage,'' she said.

``I used to work as a professional clown. My job there was to make people laugh, to make them smile, to make them joke.

``Now I want the world to sit up and do something, to make change, to stop treating 1.4 billion people like a joke.

``Since I signed up I've been very aware of what I eat and drink. I constantly find myself working out how long an item would last like my $4 piece of banana bread would have to last two days or my glass of house white would be the only thing I could ingest for three.''
