The global population has increased exponentially over the past two centuries and,

grown up organically around the many old

already standing. Some urban planners have suggested replacing some of these older

buildings

with more modern ones,

while

others believe we should preserve them. The main argument for urban renovation concerns practicality and safety.

Buildings

constructed in the modern era use new designs, materials and ideas. Many older

buildings

have structural issues that are both expensive to maintain and potentially hazardous if they contain materials,

such

as asbestos, that can cause serious health issues. Replacing them with newer

buildings

therefore

has a positive impact both on the economy and on the health and general welfare of its populace.

In addition

, modern

buildings

make better use of space, a very important consideration in cramped inner-city environments. Visiting Manhattan, many new tourists are struck by how it manages to fit nearly two million people into sixty square kilometres,

while

Barcelona, which is millennia-old, needs an area over double that size to accommodate the same number.

However

, there are limits to what can be considered sensible urban redevelopment. Many older

buildings

have great aesthetic, historical or cultural value; and the economy of a large number of

cities

today relies not only on business

on tourism. People visiting

cities

such

as Rome, Istanbul and Moscow are primarily interested in old

buildings

and other historical sites. If these were to be replaced with new constructions, the cultural heritage and identity of these

cities

would be at risk, as would much of their revenue from tourism in consequence. It is

also

important that a city’s unique history and identity should be passed on to future generations.

To conclude

, some redevelopment of urban areas is both logical and necessary for practical reasons.

Nevertheless

, it is important to remember that a city’s physical history can be an expression of its identity

as well as

an asset to its economy and that any

such

redevelopment should only take place after some very careful decision-making as to a
