Bristol Seagull Populations

From "The Times Online", 30th August 2006 ...

Bristol City Council is hoping to save £25,000 from its annual budget by sacrificing the snacks from all of its meetings and hearings.

Instead, the money will be spent on dipping seagull eggs in oil so they do not hatch.

The city is home to more than 2,000 pairs of the birds - and the population is rising by an estimated 17 per cent per year. [more]

From other research online ...

Human population [Bristol] rose from 380615 in 2001 to 421300 in 2008 - a compound growth rate of 1.4614%

What does that mean about relative human and gull populations for the next 30 years?

Could we eat seagulls? [discussion]

The table on the right shows the populations of people and gulls in 2006, and how both would continue to grow on the trends that were current at that point; I'm writing this as a PHP training course example and I have not researched further the effect of oil dipping, nor any other factors that may effect either gulls (lack of perches?) or humans (lack of decent public transport systems?) into the future.
Some more interesting things!
