The world seen through green eyes

The greening of global landmarks for St Patrick’s Day will help draw tourists to Ireland but is also part of a strategy to build the brand reputation of the food and drink industry, writes Ray Ryan

Global landmarks such as the Pyramids of Egypt, Sydney Opera House and the Empire State Building in New York will go green today.

And so too will other iconic sites including the Leaning Tower of Pisa, Niagara Falls, the London Eye and Table Mountain in South Africa.
