Concern about the planet is at an all time high and many people are keen to know how to reduce their impact on the environment. Although often overlooked and rarely mentioned, breastfeeding has a huge role to play in reducing pressure on our world. Breast milk is environmentally friendly, sustainably produced, healthy, nourishing and free. However, the reality is that only around 41% of babies are exclusively breastfed and 3.8 million tonnes of factory made infant formula are fed to babies around the world every year1. This article discusses how the manufacture of a breast milk replacement for millions of babies worldwide harms the environment.
Breastfeeding, formula and the environment
Breastfeeding does not harm the environment. International Baby Foods Action Network (IBFAN) explains:
Breastfeeding uses none of our planet’s scarce reserves of raw materials, water or grazing land, requires no fuel or energy to process and transport, and produces none of the carbon emissions, waste or pollution that contribute to the warming and degradation of our planet.
In contrast, production of breast milk replacement, often referred to as infant formula, is very energy and resource intensive. Making artificial baby milk requires land for raising and feeding dairy cattle, farming land for other ingredients, factory processing units, huge volumes of clean water, fuel heavy transportation systems, plastic and metal packaging, plastic bottles, teats, sterilising and heating equipment.
The environmental impact of formula
Industrial manufacture of baby milk contributes to waste disposal, pressure on natural resources, fuel consumption, overpopulation and over burdened health care:
#1 Waste disposal and pollution
A big issue facing the planet is domestic and industrial waste disposal for example there are over 190 million tonnes of waste to dispose of each year in the UK alone2. A particular concern is the amount of plastic waste which is difficult to recycle and takes hundreds of years to decompose3 Plastic pollution is increasingly contaminating the world’s oceans and even the rain contains microplastics.4
How does infant formula contribute to waste disposal?
- Agricultural waste. Making millions of tonnes of industrial formula per year requires many dairy herds for the milk from which it is derived leading to associated agriculture waste. The fertiliser and pesticides used to grow cattle feed adds to the pollution of waterways and ground water.
- Packaging waste. The formula industry produces millions of disposable cans of formula, single use plastic containers for ready-to-use formula, paper labels and promotional leaflets and requires millions of silicone teats and plastic baby bottles. An editorial in The British Medical Journal explains:
A 2009 study showed that 550 million infant formula cans, comprising 86,000 tons of metal and 364,000 tons of paper are added to landfills every year; the formula industry has more than doubled since then.
- Microplastics. Preparing infant formula in polypropylene feeding bottles is a huge source of microplastic release with estimates of 16,200,000 particles released per litre.5
#2 Depletion of natural resources
The formula industry requires substantial amounts of water and land putting pressure on natural resources:
- Water. We all need water to live but in many parts of the world access to clean water is scarce. Dairy farms need huge volumes of water for cows to drink, and for cleaning and sterilising, cooling milk, irrigating crops for cattle feed and moving manure. It is estimated that one kilogram of cows’ milk yields about 200g of formula powder and the water needed to make one kilogram of formula powder is 4700 litres/1241 gallons (Shenker et al, 2019). More clean water is needed at the correct temperature to rehydrate formula powder and clean equipment.
- Land for dairy farming. Dairy farming depletes natural resources when forests are cleared for grazing land. It is estimated that one kilogram of formula produced in Mexico involves the clearance of 12.5 square metres of rainforest.6
- Land for other ingredients. There are many additional ingredients in processed baby milk and the production of each has a huge impact on the environment. For example formula contains refined oils and these have a very high carbon footprint.7 Palm oil plantations involve deforestation—particularly of tropical rainforests—contributing to global warming, habitat and species loss89. Rapeseed and sunflower oils are associated with high pesticide use and harming wild bees.1011 Soy is an ingredient in some formulas and is cultivated for animal feed. Soy farming is a major cause of rainforest destruction and uses pesticides and chemicals for fertilisation that pollute waterways12.
As powdered cows’ milk is nutritionally inadequate for a developing infant, formula is supplemented with additives such as palm, coconut, rapeseed, and sunflower oils; fungal, algal, and fish oils; and minerals and vitamins. Although it remains unclear whether these supplements are nutritionally and developmentally adequate, their production has an undeniable effect on the environment.
#3 Fuel consumption
- Food miles. The distance or “food miles” a food item travels from producer to consumer is a measure of the environmental impact of that item. Producing over 3.8 million tonnes of formula every year from only 40-50 processing plants involves many food miles to send the finished product to end users (Shenker et al, 2019). China for instance imports formula from Europe, New Zealand and Australia due to lost confidence in local milk following the melamine scandal in 2008.1314
- Fuel consumption (industry). Making and marketing artificial baby milk requires large amounts of energy (fuel) to run farms and factories to process cows’ milk, manufacture bottles and teats, packaging cans and plastic bottles.
- Fuel consumption (home). Reconstituting powdered formula requires fuel to heat water/sterilise the product for the end user. One estimate suggests the energy of boiling kettles to formula feed in the first 12 months of life in the UK alone is equivalent to charging almost 200 million smartphones (Shenker et al, 2019).
#4 Overpopulation
Overpopulation is one of the main causes of man’s negative impact on the environment; the sheer numbers of people present in many cities puts increasing stress on the environment with demand for more and more housing land, farming land, clean water and basic resources. Breastfeeding has a contraceptive effect, which helps to space children and so reduce the number of offspring. Formula has no such effect so in this respect it can have a significant role to play in family size. In addition, breastfeeding delays menstruation (monthly bleeding) for an average of 14 months meaning fewer resources are needed by way of pads, tampons or cloths.
- Breastfeeding prevents more births than all other forms of contraception put together (it is also one of the few methods of birth control that does not need resources, packaging, health worker time, etc).
- In Bangladesh, breastfeeding prevents an average of 6.5 births per woman.
#5 Pressure on health care
Breastfeeding has health benefits for mothers and babies. Healthier populations with fewer illnesses and allergies need less health care and less medications using less resources.15
Promoting breastfeeding, reducing formula
Breastfeeding is an extremely important way to help the planet due to the environmental cost of the man-made alternative and the scale of the formula industry which currently involves around 60% of all babies born across the planet. More awareness is needed across society of the environmental value of breastfeeding as well as the health benefits for mother and child. Alongside this awareness, mothers need more support to breastfeed successfully. Shenker explains that a cultural change in attitude towards breastfeeding is needed:
A multitargeted approach is required, including investment in medical education so doctors can support and signpost mothers if difficulties arise, improved antenatal information and care enabling parents to develop feeding plans alongside birth plans, better access to screened donor milk from a regulated milk bank when supplementation is needed, and increased numbers of certified lactation consultants. Cultural change is long overdue to remove the myriad obstacles to breastfeeding faced by new mothers.
Finding support
This website has lots of information to help mothers breastfeed successfully such as A Good Start to Breastfeeding and Breastfeeding Tips for Newborns. There are also many International Board Certified Lactation Consultants (IBCLCs) and breastfeeding charities offering friendly mother-to-mother support and breastfeeding counsellors to help mothers succeed with breastfeeding.
Summary
Making millions of tonnes of a processed food such as infant formula, is very energy and land intensive, and creates huge amounts of waste products for disposal. In contrast, making breast milk doesn’t need factories or transportation systems, does not create pollution or toxic waste, doesn’t require deforestation, unsustainable farming practices or pesticide use, creates no packaging waste and is free. Breastfeeding instead of formula feeding is an effective way to reduce our impact on the earth and mothers need support and information to breastfeed successfully. Breast milk is environmentally friendly — formula isn’t.
It is time to start talking seriously about how reducing the unnecessary promotion, use and societal costs of formula milk feeding can help tackle the greatest challenge humanity has ever faced, sustaining Mother Earth.
Note: Sometimes infant formula is necessary and life-saving. This factual article about the environmental issues associated with the formula industry is not intended to induce guilt or shame for past or present feeding choices that individual mothers have made. This article is intended to raise awareness for the millions of parents yet to give birth who may be interested in this aspect of their feeding choices and how it can impact on the environment. It also aims to highlight the issue with campaigners, policy makers and those who are in a position to invest in breastfeeding support. There can be many challenges on a breastfeeding journey and many reasons for low milk supply. For help and support with breastfeeding issues contact a breastfeeding specialist.
