 * Pesticides have been linked to many different types of cancer in humans from breast cancer (DDT) to non-Hodgkins lymphomas and soft-tissue sarcomas (phenoxy herbicides).
 * Chronic low-level exposure to pesticides has been linked to low-grade symptoms such as headaches, dizziness, nausea, and mental confusion.
 * Linkages have also been identified between home and garden pesticide use and leukemia and brain cancer in children.
 * Agricultural spraying is by far the most common use for pesticides in Canada.
 *  Agri-business uses herbicides to kill weeds, insecticides to kill bugs, and fungicides to keep crops fungus-free all the way to the supermarket
 * . Now pesticide companies are even developing biotechnologically engineered seeds for crops that will be resistant to the chemical company's product - like canola bred to be resistant to the effects of Monsanto's herbicide glyphosate (know commercially as "Round Up Ready Canola").
 * Forest companies use herbicides to kill deciduous trees and bushes and to clear an area before planting a commercially desired species.
 *  They also spray insecticides against forest insects - often with disastrous results.
 * When the budworm outbreak in New Brunswick in 1952 was sprayed with DDT, the outbreak spread over an area four times the size of the initial spray zone.
 *  By keeping foliage alive and killing the budworm's natural predators, the spray programme kept the budworm outbreak (normally a cycle of five to seven years) in a state of artificial, permanent epidemic for over forty years.
 * Tons of pesticides are sprayed on Canada's lawns, playgrounds, parks and golf courses for cosmetic reasons.
 *  In other words, there is no economic "pest".
 * People have been conditioned to believe that a lawn marred by dandelions is unacceptable.
 *  Municipalities spend money they can ill afford to waste on herbicides. Insecticides are also sprayed by municipalities in urban areas.
 *  Winnipeg is the most heavily sprayed city in Canada, due to the yearly effort to control mosquitoes.
