It wouldn’t be unreasonable to suppose that plants mitigate any environmental harm by purifying the air as they absorb CO2 and emit oxygen.
Plants can remove “substantial volumes” of CO2 from a room, according to PhD research by environmental consultant Curtis Gubb, but the quantity depends on the type of plant, how many there are, how light the room is, and how much water is in the soil.
According to him, “The amount of water the plant receives impacts its ability to function and eliminate CO2, in a similar way to how dehydration or drinking too much water affects a person’s ability to function.”
He believes you’d still need to buy a lot of them – even creating a vertical garden or “green wall” – and have extra lighting for them to minimize CO2 levels. Dracaena “Golden Coast” plants and peace lilies performed best in his research.
Everything we do leaves a carbon footprint, according to Wong, who also contends that people shouldn’t “stress out” over their environmental influence in the grand scheme of things.
However, he suggests that if customers want to be as sustainable as possible, they should inquire about the use of peat with their suppliers, stay away from houseplants like poinsettias and sprayed cacti that are “designed to die,” and grow plants from seeds and cuttings to allay any environmental worries.
Not that those issues are major ones, he adds. However, every little amount counts.
Are indoor plants harmful to the environment?
Although they may not be having children (several economic meltdowns, a pandemic, and an impending climate crisis aren’t exactly exciting), millennials are nonetheless filling the job of caregiver. Just so happens that the objects of that care are indoor plants. The average gardener is younger and more varied than ever, according to the National Gardening Survey, with previously underrepresented groups including people of color and apartment dwellers rapidly joining the trend.
The appeal of houseplants is rather straightforward: They look wonderful and serve as small reminders of the beauty of nature. They also have a beneficial impact on one’s health. According to studies, having houseplants around makes individuals feel more at ease and has a calming impact. Additionally, they might be beneficial for ailments ranging from dementia and anxiety to depression, and some can make your environment better by purifying the air. You receive all of that in return for sporadic watering and repotting.
It’s a wonderful act of self-care to bring plants into your home, but it’s crucial to distinguish between being surrounded by plants and being green. If anything, the rising demand for houseplants in recent years has prompted actions that might be detrimental to the environment in the long run. In order to meet the demand for houseplants, which is now a roughly $2 billion industry that is expanding quickly, several farmers have tried to grow plants more quickly and ship them farther away, leaving a huge carbon footprint in the process.
How then can you maintain your home’s flora, well, green? Here are some tips for making your apartment jungle environmentally friendly.
Why are house plants harmful?

In addition to being aesthetically pleasant and adding a splash of color to otherwise dull homes or offices, houseplants can help to reduce indoor air pollution because to their capacity to absorb volatile organic compounds (VOCs). These substances are gases or vapors released by solids and liquids that may be harmful to people’s short- and long-term health. However, a recent study has revealed that some indoor plants actively release VOCs into the environment in addition to emitting oxygen and drawing out dangerous VOCs.
The Department of Horticulture at the University of Georgia organized a study to determine the sources of VOCs, the amounts of VOCs emitted by four common indoor potted plant species, and the variations in VOC emission rates over the day and night. The four plants they selected were the Areca Palm (Areca palma L.), Weeping Fig (Ficus benjamina L.), Snake Plant (Sansevieria trifasciata Prain), and Peace Lily (Spathiphyllum wallisii Regel) (Chrysalidocarpus lutescens Wendl.).
Each plant’s samples were put in glass jars with outlet ports connected to traps for measuring volatile emissions and intake ports connected to charcoal filters to supply cleansed air. To ensure that there were no pollutants, the outcomes were compared to empty containers. The Peace Lily contained a total of 23, the Areca Palm 16, the Weeping Fig 13, and the Snake Plant 12 volatile chemicals. Some VOCs are substances found in pesticides used on a variety of species during the production stage.
And it turns out that other factors other than the plants themselves are also contributing to the emission of VOCs. Along with the plastic pots the plants were housed in, which were the source of 11 volatile organic compounds (VOCs), living microorganisms in the soil were also to blame for the volatiles’ release into the atmosphere. Several of these VOCs are known to have harmful effects on humans.
The study also discovered that all species’ VOC emission rates were higher during the day than at night, and that this was true for all classes of emissions as well. This was anticipated because a number of factors, including the presence of light, alter synthesis and affect the rate of release.
The study came to the conclusion that while some VOCs are known to be removed by decorative plants, they also release a variety of VOCs, some of which are known to be toxic to people and animals. The researchers did add, however, that because the persistence of these substances hasn’t been sufficiently investigated, it is unknown how they would affect people.
The plant in the corner doesn’t seem to be as appealing anymore, does it? But take this into account before you throw any plants away. You should be grateful that plants at least absorb some VOCs in addition to producing them if the plastic pots were revealed to be the source of 11 VOCs. The amount of plastic that likely surrounds you at this now cannot be stated to be the same. Perhaps water that plant instead.
The research, Volatile Organic Compounds Emanating from Indoor Ornamental Plants, is published in the HortScience journal of the American Society for Horticultural Science.
What ways do plants hurt the environment?
This piece is the sixth in a series on invasive species being published by The Conversation Africa.
The majority of individuals concur that invasive plants are undesirable. Plants classified as invasive are those that people have unintentionally or deliberately introduced outside of their natural habitat. These species have the potential to spread quickly and harm local species.
The diversity of native species, water availability, and soil nutrient quality are all impacted by invasive plant species. Once an alien plant has colonized a habitat, it alters the ecosystem’s features. By altering the levels of light, solar radiation, and temperature in the infected regions, it achieves this. For many animals, the type and accessibility of food, shelter, nesting locations, basking sites, and perches changes.
They can also significantly modify the natural vegetation, affecting soil erosion, water availability, fire frequency, and nutrient cycling. For instance, in the Western Cape Province of South Africa, natural fynbos habitat has been invaded by pine trees that have grown outside of forestry plantations. The temperatures that lizards need to thrive in these invaded settings are often colder, and there are fewer lizard species overall.
A few instances have indicated certain advantages of alien flora. For instance, they may offer resources for animal species or supply local residents with firewood. However, the positive effects usually do not outweigh the negative ones. Through intricate interactions and processes, invasive plants have an effect on native species. It is challenging to foresee what kind of influence invasive plants will have without a thorough understanding of these aspects.
In South African environments, where invasive alien plants are a major concern, how much is known about these processes? We read every South African paper we could find on the effects of alien plants on animals in order to identify the solution, and we then reported our findings in a recent study. We concentrated on ectothermic, or “cold blooded,” animals, such as reptiles, amphibians, and invertebrates. For them to live, grow, and reproduce, the environment must exchange heat with it. These animals often travel shorter distances than mammals or birds, which makes them more susceptible to invasions by non-native plants.
Do houseplants benefit the environment?
The greatest plants for lowering indoor air pollution at home are identified by Rebecca Jeffreys.
Some may contend that a plant transforms a house into a home. If you take care of it properly and don’t hang your head in shame every time you go past it waving its brown leaves at you, it will look fantastic in any corner of the room and be more sustainable than a bouquet of flowers. But more often than not, people purchase home plants purely for aesthetic reasons, oblivious to the numerous advantages they offer.
According to the World Health Organization, pollution causes the deaths of 7 million people each year. For context, 8.136 million people were estimated to reside in London in 2011. And despite the fact that we believe our four walls will shield us from the pollution outside, research has revealed that harmful toxins may also be found indoors. Fortunately for us, research has shown that some indoor plants can operate as a natural filter to reduce indoor pollution. In fact, over 50 different varieties of houseplants have been discovered to remove toxins and gases, according to NASA-conducted research on the benefits of indoor plants.
Additionally, plants have been proved to reduce stress levels at home and at work. As if that weren’t enough, they also tout the following additional health advantages:
1. They improve your sleep 2. They support cold prevention 3. They aid concentration 4. They contribute to greater wellbeing.
The top 10 plants that can enhance the quality of the air in your house are listed below:
What drawbacks are there to having plants inside?
Indoor plants’ drawbacks and disadvantages
- Allergies. Research has showed that many popular houseplants may filter the air of hazardous chemicals, according to NASA, which researched the purifying properties of houseplants.
- poisonous black mold The majority of houseplants need a lot of water and are often wet.
- Pests.
What plant is most environmentally friendly?
You probably have at some point in your life fallen for an air cleansing system or device that is not natural or doesn’t really perform what is stated on the box, from air purifiers to air filters and HEPA vacuums. The EPA lists indoor pollution levels as one of the top five environmental dangers to the general population. Indoor pollution levels may be up to 100 times greater than outside pollution levels. Therefore, it is critical that you address these pollutants in your living and working places.
What is the remedy? Eco-friendly, air-purifying plants are the solution, even though it may seem obvious or make you wonder why you hadn’t considered it before. In 1989, NASA’s Clean Air Study did the legwork for us, determining that plants were the most efficient air purifiers in space stations, a conclusion that is still relevant for modern interior air purification.
They discovered that certain plants were particularly good at eliminating dangerous airborne pollutants like benzene, formaldehyde, trichloroethylene, xylene, and ammonia, which have been associated to symptoms like headaches, nausea, and eye irritation.
The most effective plants for air purification, according to NASA research, are listed below.

Are plants a better air cleanser than filters?
We regret having to inform you, but no. In any actually achievable number of houseplants, and most definitely not in an average number of plants way. Sadly, it is largely untrue that plants can successfully purify indoor air.
Of course, plants take in carbon dioxide, undergo photosynthesis, and release oxygen back into the atmosphere. The underlying hypothesis was that plants could be able to absorb other air pollutants, such as volatile organic compounds, in addition to carbon dioxide (VOCs). This is accurate in theory. However, houseplants don’t qualify as air purifiers because of how slowly they can remove VOCs from the air.
