The Link Between Fossil Fuels, Single-Use Plastics and Climate Change
By Katie Day and Trent Hodges
When we think of plastic pollution, we think of images of plastic bags on the beach, suffering marine life and the almost invisible smog of microplastics in our ocean. What often gets overlooked is the fact that conventional plastic is made from fossil fuels, and is a product of the oil and gas industry.
Traditionally made from petroleum byproducts, plastic in the U.S. is now most commonly sourced from the nation's production of "abundant and affordable" natural gas. Natural gas liquids (NGLs) ethane and propane get extracted and sent to a "cracking facility" where ethane is made into ethylene (the foundation of polyethylene—the most common plastic in the world, frequently used for packaging, bottles and synthetic clothing), and at a dehydrogenation plant, propane is made into propylene (the foundation of polypropylene—a plastic commonly found in food packaging and vehicle manufacturing).
"The reason is simple: because of shale gas, it is more cost effective to produce ethylene in U.S. than just about anywhere else in the world."
— Excerpt from American Chemistry Council
The U.S. natural gas boom has made plastic feedstocks really cheap and readily available. An estimated $50 billion will be invested into new and expanded U.S. plastic production facilities, increasing production by roughly 50 percent in the next 10 years, and tripling the amount of plastic exports by 2030! That includes 400 new plastic processing facilities, in addition to plastic manufacturing facilities and plastic additive processing facilities, which can produce some significantly harmful chemicals including pthalates and brominated flame retardants.
In fact, in the U.S. alone, producers of polyethylene are expecting to increase production capacity by as much as 75 percent by 2022. Industry explains that this increase of production is fueled by expected increases in demand for disposable plastics, such as soft drinks and packaging, by millennials in developed countries, and growing consumer markets in developing countries. This means that much of the U.S. manufactured plastics are planning to be exported to developing countries, where waste management services may not be properly equipped to handle current, let alone a surge in non-biodegradable solid waste.
This is disheartening news, but just as the proposal for offshore oil drilling off the U.S. ignores the fact that the world is moving towards renewable energy, the plastics industry fails to recognize the proliferation of social and political changes such as bag bans, foam bans and society's refusal to accept an inundation of single-use plastic.
The movement to reduce single-use plastic pollution has gone global. At the local level, cities across the U.S. have banned and restricted the unregulated use of wasteful single-use plastics, fueled by campaigns that Surfrider chapters and passionate communities have fought for. On the international side, in January 2018, the European Commission announced a Europe-wide strategy to reduce plastic pollution and ensure that all plastic in Europe is recyclable by 2030.
Even the UN Environment Program has taken a strong stance against plastic pollution, and started a global campaign to reduce marine debris from microplastics and single use plastics by 2022. Though none of these actions alone signal an end to single-use plastics, they do show the increased resistance among cities, nations and the international community to reject products that are used once and thrown away to the detriment of our waters, land and wildlife.
Plastic pollution is an issue that demands worldwide cooperation, similar to climate change, as they are two sides of the same coin. As a product of extracting and refining fossil fuels for energy, the amount of plastic produced is influenced by the demand for and production of oil and gas. Industry analyses find that the production of plastics from fossil fuel is only cost effective when the components not used for plastics are used for energy production, treating plastic more as a byproduct of the industry. Therefore, if we transition away from fossil fuels, and towards renewable energy and a healthy climate, we also encourage industry to transition away from producing wasteful single-use plastics.
"Plastics manufacturers assume demand for disposable plastics will continue to rise, despite evidence that global awareness of plastic pollution is growing and cultural attitudes are changing. Industry investments reflect a further underlying assumption that supplies of cheap hydrocarbons will remain the norm for decades to come, even as the global community has begun to phase out the very fossil fuels upon which plastics producers depend."
— Excerpt from Center for International and Environmental Law
This makes the fight against single-use plastic pollution more compelling and holistic, realizing that good choices in renewable energy and climate friendly decisions may also help reduce single-use plastic production and pollution, and vice versa.
We need your help to reduce the consumption of single use plastics and fossil fuels!
- Support bans on harmful single-use products through local campaigns.
- Support Ocean Friendly Restaurants and local businesses that avoid plastic waste while spreading awareness of the issue.
- Reduce your reliance on greenhouse gas emissions by driving less, investing in high-efficiency lighting and appliances, and buying locally.
- Adopt a single-use plastic free lifestyle by investing in reusable cups and cutlery, purchasing loose produce instead of packaged produce, and saying no to plastic straws, bags, bottles, and takeaway containers.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.
