The ozone layer absorbs ultraviolet radiation that can be very harmful to all forms of life. In 1974, however, scientists discovered that chlorofluorocarbons (CFCs), a chemical used in aerosol sprays, refrigerants, and the creation of synthetic materials, break down when they enter the stratosphere, and produce a chlorine atom, which then contributes to breaking down the ozone layer. In 1985, British Antarctic Survey scientists discovered a massive hole in the ozone layer above Antarctica.
In 1967 Yorkville Village, Toronto was a neighborhood inhabited by many aspiring artists, hippies, greasers, bikers, youth, and others looking to embrace the counter culture lifestyle. This lifestyle attracted many youth who travelled from all across Canada to experience the environment Yorkville offered.

In October of 1998, environmental groups organized protests against Home Depot, the world’s largest do-it-yourself hardware and supply store. The protests were in response to the purchasing and selling of old-growth wood (OGW), or wood from endangered, never before forested regions.

These particular products, as well as the pelts themselves were exported to other countries for further use. The hunt of these animals was also beneficial to ensure the number of cod fish remained high.
