Madam Speaker, there will indeed be major environmental consequences. Take, for example, water consumption. Water consumption is one of the environmental concerns, but there is also water pollution. Waste water has to be treated. There is also waste management. Waste has to be handled properly and safely stored. There is also atmospheric pollution, air pollution and greenhouse gas emissions. There are tons of different forms of pollution and repercussions associated with the presence of humans that will be felt if we increase the population more quickly than what nature can handle.
