People are being invited to sit down to eat with their neighbors in a nationwide lunch party designed to promote community spirit. The Big Lunch is the idea of the Eden Project in Cornwall. It aims to persuade people up and down the country to hold street lunch parties.

Tens of thousands of vegetables, fruits and flowers were used to construct a giant 2,000-square-foot lunch invitation in London’s Convent Garden. More than 9,000 cauliflowers and 800 bananas were used.

According to the organizers, people who decide to take part in the activity will get support from large companies which will supply many of the necessities, including plants to be given out to people to grow. The organizers think that the Big Lunch is a great opportunity for people to get together and spend time with their neighbors, friends and families. Events like this also help build strong communities. People can show their talents, get over their embarrassment, shake hands and get to know their neighbors, and realize that the neighborhood where they live can be a great source of happiness and enjoyment.

The Eden Project’s leader, Tim Smith, says, “It’s a good way to face this recession. Imagine a day on which millions of us, throughout the UK, sit down to have lunch together with our neighbors in the middle of our streets, around our tower blocks, and on every patch of common ground. We’ll have cooked our own food, made our own entertainment, and created our own decorations. It will be a day to share bread with our neighbors, and put a smile on Britain’s face.”
