Earlier this year, during the Rio+20 Earth Summit, UN-Habitat
(i.e. an UN agency dealing with promoting sustainable urban
development) launched its “I'm a City Changer” campaign. The end
goal for this campaign is that of greening up cities all
throughout the world, simply by convincing more citizens to
actively get involved in on-going environmental projects and
even take initiatives in implementing new ones. This video is
meant to raise awareness with respect to what will happen if
urban areas are not soon transformed in such ways that they can
meet the requirements of the ever-growing population without
putting too much stress on existing resources. “Nowadays more
than half of the population resides in urban areas and we are
living a unique phenomenon of urban population increase."
"Cities should not be considered as problems; cities are the
opportunities to face global challenges,” argued the report
released when this campaign first made its debut.
