Cities are growing in size and in population. As they grow, will they have a harmful impact on
the environment? Not necessarily. Many city planners have solutions to make cities and the
people who live in them healthier and happier, while at the same time, having a positive
impact on the environment. Three ways to improve cities include creating green spaces,
developing mixed-use areas, and encouraging building owners to transform their rooftops
into gardens. Green spaces have a positive impact on a community. They are protected
areas that remain undeveloped, such as parks or other open areas. Increasing the number
of green spaces in a city has several advantages. Green spaces make a city more attractive,
as plants and other features such as streams and rocks- are left in their natural state. Green
spaces also provide peaceful recreation areas for city dwellers. People can walk, hike,
bicycle, and picnic in these areas away from the hustle and bustle of city life. Trees also
shelter the area from the noise and traffic of the city while improving the air quality. Another
way to improve the quality of life in cities is the development of mixed- use areas. Mixed- use
areas combine several purposes in one space. A mixed- use area, for example, may contain
offices and businesses, apartments, and entertainment facilities. Ideally, mixed- use
developments attract people who want to live and work in the same area. The benefits to the
community are significant because mixed- use areas allow people to reduce the amount of
time they spend in cars driving to work and running errands, which in turn reduces air
pollution. Creating mixed- use areas with pedestrian- and bicycle- only streets further
lessens the impact on the environment, and it can also encourage better health and fitness
as citizens spend less time in cars. Finally, encouraging building owners to convert their
rooftops into high- rise gardens and farms can bring about dramatic changes to city life and
improve the environment at the same time. Rooftop gardens insulate buildings. For example,
in areas that have hot summer weather, rooftop gardens can cool buildings so that they don't
require as much air conditioning. This reduces energy use as well as the cost to building
owners. Rooftop gardens that are used to grow organic fruits and vegetables as opposed to
those grown with chemical compounds can also improve the quality of life for city dwellers,
especially if they live in areas where access to fresh produce is limited. Limiting the use of
harmful pesticides through organic gardening is good for the planet and for human health,
too. Green spaces, mixed- use areas, and rooftop gardens are just a few of the ways that we
can lessen the impact of cities on the planet. By instituting these and other methods to make
cities more livable and environmentally friendly, we can look forward to a happy and healthy
future as our cities grow.
