Passage Three
For many years, people in American cities have depended on farmers in rural areas to grow fruits and vegetables. ____1____Sean Conroe and Amber Banks both grew up farming and gardening. They wanted to start a farm in the middle of Seattle, Washington. Amber Banks says, there are a lot of neighborhoods that don’t have access to healthy, fresh produce. And if they do, it can be very expensive. ____2____ Sean Conroe created a website to get volunteers and donations. Within a week, they were offered a plot of land between two houses. He says twenty volunteers worked for six weekends turn the grassy land into a farm. They call their project Alleycat Acres. One of the goals of the urban farm is to show city people the joys of growing food. They also invite school groups to the farm to help out. ____3____Seattle has declared two thousand ten“The Year of Urban Agriculture.” But the growth of these farms is limited. That is because Seattle, like a lot of other cities, has legal restrictions on urban farms. The City Council is now considering changing those laws.
