In the economic recession of 1999, and the stagnant years of 2000 and 2001, some residents of Pereira emigrated to the United States and Spain. Towards the years 2005 and 2006, Pereira recovered from decline and went into an economic boom, with new office, retail and housing development, and most importantly Megabus, the main public transportation system, opening to the public. In 2015 the new Biopark Ukumari was opened to the public in its initial phase with 2 bioregions. It is planned to have up to 8 bioregions including the Andean Mountains, African desert, Amazonas and many more, including a section designed for mechanical rides.
