Climate Change is Impacting Your Life in More Ways Than You Think
It's not just an environmental problem…
We know climate change poses a real and serious threat; scientists have observed Earth’s temperature steadily rise by one degree Fahrenheit over the last 100 years (1). But when we think of climate change, an image of a polar bear on a dwindling iceberg usually comes to everyone’s mind. There’s so much emphasis on the environmental impacts of climate change, we often forget that climate change is also negatively impacting our health. How? Read on…
Even though you can’t see it unless it’s a super smoggy day, air pollution is a huge threat to our health. Burning coal, oil, and gas are big contributors to climate change, and they also release harmful air pollutants like particulate matter, nitrogen dioxide, ozone, and sulphur dioxide into the atmosphere. These pollutants have been linked to serious diseases, and can cause severe symptoms in people with heart and lung conditions. When you breathe in, these pollutants get trapped in your nose, travel to your airway, and even enter into your bloodstream. Exposure to these pollutants have been linked to death in people with heart or lung disease, heart attacks, irregular heartbeats, aggravated asthma, decreased lung function, and increased respiratory symptoms (2). It is estimated that 4.2 million people a year die from air pollution (3).
Extreme Weather Events
Nowadays, it’s hard to not hear about extreme weather on the television or radio no matter what time of year it is. Extreme weather events like heat waves, drought, floods, and hurricanes are increasing both in intensity and frequency due to climate change. The Center for Climate and Energy Solutions created an interactive map that highlights just how many extreme weather events occurred in the past decade. The Guardian also has published a visual guide of the human toll from 2018 climate disasters. In 2018 alone, Europe faced both heatwaves and freezing weather, Argentina suffered through droughts that decimated croplands, India experienced record high flooding, and the United States endured hurricanes and fires. That same year, 10,373 people lost their lives due to disasters, and 61.7 million people were affected by natural hazards (5). As climate change continues, these numbers will only get worse.
Increased Vector-Borne Disease
Very few things can ruin a beautiful summer day, but a swarm of mosquitoes is definitely one of them. Just the thought of their buzzing has us lathering on bug spray and lighting citronella candles! Unfortunately, with worsening climate change, we are in for a lot more buzzing.
Changes in temperature, rainfall, and humidity brought on by climate change have allowed vectors like mosquitoes, ticks, and rodents that carry infectious agents to migrate to new areas (6). With the expansion of their habitats and breeding grounds, these vectors are coming into contact with more people, and more interactions with people means more chance of infection. We’ve seen higher incidences of diseases like malaria, Lyme disease, and West Nile virus in recent years. To make things worse, a warming climate also allow vectors and the microbes inside of them to grow and reproduce at a faster rate (7).
What You Can Do
While the statistics on climate change are sobering, there’s a lot you can do to protect your health! Being prepared and taking small precautions can keep you safe no matter what a changing climate throws at you.
- If you are travelling to a heavily polluted area, you can limit exposure to harmful pollutants by wearing an air mask. Look for masks called a “particulate respirator” with the word “NIOSH” and either “N95” or “P100” on the package information. Make sure to replace your mask with a new one every few days (if the mask if reusable to begin with).
- If you live in a buggy area, apply bug sprays before going out to ward off disease-carrying insects and reapply when necessary. Check out our insect repellent guide to find out which repellent is right for you!
- And if you live in an area that is prone to natural disasters, purchase or assemble an emergency kit to store in your home. There are kits that are specific for flooding, hurricanes, heat waves, and other natural disasters. Make sure to have these kits readily available know how to use them.
