When we talk about food farming, we usually think of green fields in the countryside, far from the city.
Last year, Sam Chee (work) on a very different kind of farm, in the center of Toronto. He grew fruit, vegetables and herbs. But not many people knew the farm was on top of a building, fifty (meter) above the ground.
The tops of buildings are often just wasted space, Sam can use this space to grow food. He tells us it works, "We grow everything in big pots and boxes—there are hundreds of them. We save rain (water) the plants when the weather is dry."
The rooftop farm belongs to a restaurant called Green Garden. About half the restaurant's vegetables (produce) there. It is the rooftop farm that makes Green Garden special. Sam and his workmates don't need to buy vegetables from anywhere.
The food from the rooftop farm is (real) fresh, too. "When the fruit and vegetables are ready, we can pick and use (they) right away. They taste much (good) than those from normal farms," says Sam. "I hope that there (be) more rooftop farms in the city soon. It could be the farming of the future."
