This week, the human population reached a new milestone – 7 billion. The exact time of birth of the 7-billionth baby was unknown but births in general around the world on Monday 31st October 2011 were celebrated.
Amid the celebrations however, are an increasing number of voices concerned with the strain that humanity’s growing population is placing on the environment and resources around us. These fears are particularly relevant for poorer, developing countries where people do not always have reliable access to the basic elements needed for survival e.g. water, food, fuel and shelter.
