The fast growth of Toronto increases the demand for building materials such as concrete and steel for larger constructions and wood and bricks for the smaller ones. The growing population and a large number of tourists and international students that use the restaurants, bars, cafes, groceries and supermarkets lead Toronto to rely on external food supplies. Products from animals such as meat and milk come from other parts of the country while a significant part of the fresh vegetables are imported from US and Mexico. Petrol is the main source of private transportation energy in Toronto so that there is a constant flow of this product into Toronto from Quebec. Part of the public transportation works by electricity which increases the need for more sustainable ways of producing this type of energy. Immigration is one factor that contributes to the quick change of the density of population in Toronto. With people coming from different parts of the globe, looking for better opportunities and quality of life, all the other essential elements must be adapted to supply the growing demand. Outputs: Toronto is an important business and educational center so that it exports services and information to other areas in development. Although a large part of the wastes in the city is either recycled or compostable, huge amounts of waste are produced and taken to the green landfill in St Thomas to generate gas. Stocks: As for the water supply, Toronto is served by the adjacent Lake Ontario which was formed in the last glacial era. As everything in nature, it’s continuously in change; but, if compared to the other elements, its transformation is so slow that it can be considered stable in a period of time. ![enter image description here][1] [1]: https://edxuploads.s3.amazonaws.com/14159798466653261.jpg
