Many cities are trying to become greener. They are planting more trees along streets and near schools. Trees give shade on hot days and help make the air cleaner. Green spaces also give people places to walk, rest, and play.
Cities are changing their roads, too. Some streets now have safe bike lanes. More people can ride bikes instead of driving short distances. This can reduce traffic and air pollution.
Public transportation is another part of a green city. Buses and trains can carry many people at one time. If more residents use them, fewer cars are needed on the road. Some cities are also using buses that run on electricity.
People can help with these changes in simple ways. They can bring a reusable bag, save water, and put trash in the right bin. They can walk, ride a bike, or take a bus when possible. A greener city needs both good city plans and daily action from its residents.
