A 2010 study showed that incidences of cancer in Native Americans from the Northern Plains are more likely to be fatal than for Native Americans from elsewhere due to lack of cancer screening tests. It is important to understand how climate change could increase cancer among Amskapi Pikuni community members. Our decisions and actions can influence the degree to which our community will or will not experience these impacts to our health. Being proactive and making decisions now to safeguard health will help us be more resilient.
How climate change could increase the incidence of cancer:
High levels of indoor air pollution and fine particulates may increase the risk of lung cancer.
Climate change is expected to deplete stratospheric ozone, which would increase ultraviolet radiation exposure, increasing the risk of skin cancers and cataracts.
Increased precipitation or flooding has the potential to increase toxic chemical and heavy metal leaching from storage sites. Exposure to chemicals that persist in the environment may also increase if runoff enters the water supply.
Who is most at risk?
In addition to exposure to harmful chemicals and ultra-violet radiation, many other factors influence cancer risk, including age, family history, viruses and bacteria, behaviors like tobacco use, high levels of alcohol consumption, obesity, an unhealthy diet, and sun exposure. For more information about cancer risks associated with chemical exposure, see this guide by the Agency for Toxic Substances and Disease Registry.
How can we adapt?
Make community development decisions that promote active, healthy lifestyles (see suggestions here).
Increase access to healthcare for all Blackfeet.
Properly identify and manage waste disposal and chemical storage sites and prepare them for high precipitation events and flooding. (Kim Paul, a Blackfeet tribal member, has investigated stories of unidentified contaminated waste dump sites in Blackfeet Country and described her findings here.)
Reduce the amount of chemicals in the environment so that fewer chemicals enter run-off. For example, encourage agricultural practices that reduce pesticide and herbicide applications and practices that buffer farm areas from streams and lakes to help reduce the amount of chemicals entering the water supply.
Plant trees, encourage people to stay indoors during extremely poor air quality days, and use other techniques to adapt to diminishing air quality.
The Blackfeet (Amskapi Piikani) have long believed that we are the caretakers of the land and resources where we have resided for many thousands of years. To this day, we use this land for spiritual and cultural purposes. The Blackfeet Nation strives to retain its culture in this modern era where impacts to our world are changing, and we recognize we must adapt.”
