Make least-toxic the norm. Counter vested interests that thwart health.

Action Agenda

Major farming groups and experts agree that substantial pesticide reduction and adoption of organic practices are essential for Sustainable Agriculture and food security. See PCN’s federal submission, and ask your MP to support truly sustainable agriculture.

THANK YOU for taking action! Municipalities across Canada have a concerning number of old asbestos cement water supply pipes that can contaminate drinking water. Public response means that this petition is certified — the Federal Government must publicly respond to citizens’ request that it take immediate steps to assess and act on the health risks.

Mar. 23, 2023 / A major peer-reviewed publication reports that many aspects of child development can be affected by radiofrequency “wireless” radiation, and screen time.

Leading international scientists find impacts on bonding, speech acquisition, behaviour, socialization, learning and addictions. Cancer risks are also increased.

Recommendations include use of wired technologies, that wireless radiation exposures be “ALARA” (as low as reasonably achievable), that physicians query use of tech in well-child visits, and research to prevent and investigate electrohypersensitivity.
