Synergy Session: The Problem with Pesticides
Friday, February 12th
McCann Centre, Memorial University, St. John's
About the session:
Pesticides – insecticides, herbicides and fungicides – have played a role in expanding agricultural production for seventy years. They have been used to kill pests of all kinds, including insects, plant pathogens, weeds, molluscs, birds and microbes that destroy property, spread disease or cause a nuisance. Although there are benefits to the use of pesticides, there are also drawbacks, such as toxicity to humans and other animals. These drawbacks have tended to be underestimated until recent years. According to the Stockholm Convention on Persistent Organic Pollutants, 10 of the 12 most dangerous and persistent organic chemicals are pesticides. The use of pesticides has been connected to cancer, birth defects, fetal mortality and neurological disorders.
Pesticides have been found in pristine ecosystems far from the sources of application, including at both Poles. Pesticides not only affect target and non-target species (including species at risk) but contaminate human food supplies and sources of medical compounds. In the last few years, pesticides have contributed to a decrease in both domestic and wild bee populations by one third; this impacts human food production, as one third of food supplies depend on pollination by bees.
What is the situation regarding pesticides in Newfoundland and Labrador? What links have been established between pesticide use and health or agricultural problems in the province? What alternatives are there to pesticide use that might have less impact on health and agriculture? Are new policies needed to establish a better balance between the use of pesticides and their negative impacts on populations and crops?
