I was shocked to read that three out of four popular fish species eaten in Singapore are environmentally unsustainable ("Risk of your favourite fish going extinct"; yesterday).

There needs to be more education in schools and more awareness campaigns for Singaporeans to be aware of this grim reality.

More information needs to be easily available to Singaporeans about what they can do to mitigate this.
