Answer 1

Urban greenhouse

Step-by-step explanation:

People in cities all over the country are growing small crops in cities. They may be on vacant land or even a rooftop. This brings more fresh fruits and vegetables into the city at a lower price. Since the food does not have to travel far, it saves energy and reduces the amount of greenhouse gases emitted into the air. Some disadvantages are lack of space, the need for extensive ground preparation due to poor soil quality, and use of fertilizers and pesticides.
