Urban build-up is on the brink of a total environmental calamity. Rising levels of pollutions in air, water and excessive heat have made living difficult. Of these, heat in cities makes air dull and heavy. Foul and hot air have turned cities into large heat centres. Heat trapped within the concrete jungle makes it difficult for residents. Due to high rises, heat is unable to escape. The air is never fresh. Human activities worsen the situation. Collectively, factors like excessive use of vehicles, the release of greenhouse gases and the use of Air Conditioning(AC) have worsened the situation.
