World urban population is expected to increase by 84 per cent by 2050. Overpopulation threatens basic life-sustaining resources, access to clean air and clean water as well as energy use, waste and pollution produced, which will eventually lead to diminishes quality of life. Over 80% of world population is currently living in urban areas, as our population grows bigger in number, the size of the cities grows bigger as a consequence of URBAN SPRAWL, the over development on green field puts extra pressure on our natural environment.
Climate change is projected to become the fastest growing driver of biodiversity loss by 2050, followed by commercial forestry. The consequent loss and degradation of urban and peri-urban green space could adversely affect ecosystems as well as human health and wellbeing.
