World Environment Day serves as a global platform to raise awareness about environmental issues and promote sustainable living. As the world grapples with pressing environmental challenges, it's imperative to instil a sense of environmental responsibility in the next generation. Parents, as the primary educators of their children, have a unique opportunity to shape their children's attitudes and behaviours towards the environment. By teaching their children eco-friendly habits, parents can instil a sense of environmental responsibility that will benefit both their children and the planet.

Here are some eco-friendly habits that parents can teach their children to foster a more sustainable future. These habits focus on reducing waste, conserving resources, protecting wildlife, and making environmentally conscious choices. By incorporating these practices into their daily lives, children can contribute to a healthier and more sustainable planet for generations to come.

Habits Kids Should Learn

Parents play a crucial role in shaping their children's attitudes and behaviours towards the environment. Here are 9 eco-friendly habits parents can teach their children:

Reduce, Reuse, Recycle

Teaching children the principles of reduce, reuse, and recycle can help them develop a mindset of sustainability. Encourage them to think critically about their consumption habits and find ways to minimize waste. By reducing their consumption, reusing items whenever possible, and recycling materials, children can make a significant contribution to environmental protection.

Conserve Water

Water is a precious resource that is essential for life. Teach children the importance of conserving water and demonstrate practical ways to reduce water usage. This could include taking shorter showers, turning off the faucet while brushing teeth, fixing leaky faucets, and using water-efficient appliances. By conserving water, children can help to protect our planet's natural resources.

Save Energy

Energy consumption has a significant impact on the environment. Teach children how to conserve energy by turning off lights when not in use, unplugging electronics, and using energy-efficient appliances. Explain the benefits of energy conservation, such as reducing greenhouse gas emissions and saving money on energy bills.

Plant Trees

Trees play a vital role in the environment by absorbing carbon dioxide, providing shade, and supporting biodiversity. Encourage your children to plant trees in your community or backyard. Explain the benefits of trees and the positive impact they can have on the environment.

Compost Food Waste

Composting food scraps is a simple and effective way to reduce waste and create nutrient-rich soil for gardening. Teach children how to set up a compost bin and the benefits of composting for the environment. By composting, children can help to reduce landfill waste and create a more sustainable ecosystem.

Choose Sustainable Products

Encourage your children to choose products that are made from sustainable materials and have minimal packaging. Explain the importance of supporting businesses that prioritize environmental responsibility. By making conscious choices, children can help to reduce their environmental impact.

Reduce Plastic Consumption

Plastic pollution is a major environmental problem. Teach children the harmful effects of plastic and encourage them to use reusable bags, water bottles, and containers. Explain the importance of reducing plastic waste and the positive impact it can have on our oceans and wildlife.

Educate and Protect Wildlife

Wildlife plays a crucial role in maintaining a healthy ecosystem. Teach children the importance of wildlife conservation and encourage them to respect and protect animals. Explain the threats facing many species and the steps they can take to help protect them.

Walk, Bike, or Take Public Transportation

Reducing car pollution is essential for protecting our air quality and combating climate change. Encourage your children to walk, bike, or take public transportation whenever possible. Explain the benefits of reducing car use, such as improving air quality, reducing traffic congestion, and promoting physical activity.

Digital devices have become the new pacifiers, said Zerodha co-founder Nithin Kamath, raising concerns about the growing impact of excessive screen time on children's behavior and brain development.

Posting a video of cognitive neuroscientist Jared Cooney Horvath on his social media platforms, Kamath warned that while digital devices often help parents manage their schedules, they can also create long-term dependency among children.

"For most parents, digital devices have become a pacifier; it's a way to keep 'em quiet, and it's understandable, but it ends up creating a dependency in the long run," Kamath said.

In the video, Horvath spoke about a decline in learning abilities among younger generations due to the increasing screen time. Horvath said children today appear to lag behind previous generations in areas such as attention span, memory, literacy, numeracy, and executive function, despite spending more time in formal education.

Kamath noted that his son studies at a school where digital devices are not permitted, and screen use at home is restricted to 30 minutes a day. Despite these limits, the billionaire entrepreneur pointed out how quickly children become drawn to short-form digital content.

"At Kiaan's (son's) school, no digital device is allowed, and at home, we restrict screen time to 30 minutes a day. But even then, it is crazy, the addiction to reels/clips; I normally catch him browsing through that," the billionaire entrepreneur said.

Horvath said children today appear to lag behind previous generations in areas such as attention span, memory, literacy, numeracy, and executive function, despite spending more time in formal education.

Long Screen Exposure Can Impact Vision, Brain Development

Dr Sriram Simakurthy, Chief Medical Officer, Sankara Eye Hospital, Hyderabad, flagged the risk of excessive screen exposure in children with eye health.

“Children can develop particular vulnerabilities because they spend extended periods using screens without taking breaks, and they struggle to identify their symptoms before they become serious. Children who spend extended time looking at screens will face an increased risk of developing myopia (near-sightedness),” the expert said.

Prolonged screen exposure causes people to blink less frequently, which leads to unstable tear film production that results in dry eyes and eye irritation.

Dr. Sreenath S Manikanti, Clinical Director & Senior Consultant - Neonatology and Pediatrics, Rainbow Children’s Hospital, said that kids' eye health gets harmed by excessive screen exposure through mechanisms that extend beyond digital eye strain.

“The extended periods of near-focus work, which include watching screens for too long, create a permanent requirement on the eye to focus, which leads to visual fatigue and alters normal eye development in children. The period of visual system development happens throughout children's growing years,” the expert said.

Dr. B K Madhusudhan, Lead Consultant – Neurology, Aster RV Hospital, Bengaluru, noted the impact of screen time on brain development.

“The brain development process in children gets disrupted when they spend too much time using screens because that time replaces their necessary developmental activities. The continuous use of screens results in decreased attention spans, which makes it difficult for children to maintain focus during extended periods and to complete tasks that require their full attention,” Dr Madhusudhan said.

When screen time replaces parent-child conversations, storytelling, and peer interactions, this change impacts language and communication development. These experiences help children develop vocabulary skills and reasoning abilities as well as social understanding.

“Some children also develop impulsive behavior patterns and struggle with emotional control and information processing because they spend excessive time using screens,” Dr. Madhusudhan said.

How To Prevent?

The experts advised people to balance their screen use with outdoor time.

• Take breaks following the 20-20-20 rule
• Keep a proper viewing distance
• Schedule eye examinations for children at regular intervals.

We are all aware of the fact that the use of plastics causes harm to our environment, and dangerously so. But what will happen when we realize that plastic can enter our bodies too?

As far as gynecological reproductive health is concerned, the major emphasis has always been on genetic aspects, hormonal imbalance, and even the choice of food and regular exercise. PCOS and endometriosis are both known to cause health concerns in women during menstruation and during or after sex. However, today there is another threat to the health of women’s reproductive organs in the form of microplastics and nanoplastics.

Can these enter the ovaries and result in greater damage to women’s sexual and reproductive health? The answer, unsurprisingly, is a yes. Microplastics, along with nanoplastics, have actually been detected in ovarian tissues and in follicular fluid.

Understanding The Invisible Intruder

To grasp the scale of this issue, one must first define the particles involved. Microplastics are tiny fragments of plastic less than five millimeters in size, while nanoplastics are less than one micrometer. These are so small that they remain invisible to the naked eye and can easily bypass the body’s natural biological barriers.

They can be identified as multiple polymers, including polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET), commonly used in packaging and agricultural materials. The 2024 Science of the Total Environment study, which used Py-GC/MS to confirm the presence of polymers such as polyethylene and PVC in human follicular fluid for the first time. Out of the 18 women sampled, over 80% had microplastics in their follicular fluid.

The ovaries were once thought to be a protected zone, shielded by complex filtration systems. It is now understood that these particles enter the bloodstream through food, water, and even the air we breathe. From the bloodstream, they can directly seep into the reproductive organs too. Common polymers like polyethene found in plastic bags, and polystyrene used in packaging, are now being identified in the very fluid that determines the quality and competence of a woman’s oocytes.

The Trojan Horse Effect: How Damage Occurs

From a clinical standpoint, the concern is not just the presence of the plastic itself, but the Trojan Horse effect it creates. These particles often carry Endocrine Disrupting Chemicals (EDCs). When these particles lodge themselves in ovarian tissue, they trigger several harmful processes:

• Oxidative Stress and Cellular Ageing – The presence of a foreign object in the ovary triggers the production of Reactive Oxygen Species (highly reactive molecules derived from oxygen). This is a form of cellular rusting as oxidative stress can damage the DNA of the oocytes and potentially cause poor maturation and a decline in overall egg quality at an early stage of their life.
• Hormonal Mimicry – Most plastics contain chemicals that mimic estrogen. When these enter the follicular environment, they disrupt the natural signaling of progesterone and estrogen. This can lead to irregular menstrual cycles and has been linked to conditions such as Polycystic Ovary Syndrome (PCOS).
• Mitochondrial Dysfunction – Nanoplastics are particularly invasive because they can penetrate cell membranes. Once inside, they can disrupt the mitochondria, which are known as the cell’s powerhouses. Since an egg cell requires an immense amount of energy to develop and eventually fertilize, any disruption to energy production can compromise fertility. Also, plastic is eternal; it's very difficult for the human body to dissolve it and remove it from the body.

From Environment To Egg: The Journey Of Exposure

It is important to recognize that this is a cumulative issue. Human beings are exposed to these particles through multiple daily touchpoints:

• Ingestion: Microplastics shed from plastic water bottles, especially when heated. They are also found in ultra-processed foods and certain seafood. We should immediately stop using plastic containers for storing food and water, and shifting towards glass containers and copper bottles can be more beneficial both for the environment and for the body. Heat is the primary catalyst that causes plastics to leach into food and water. Switching to glass, ceramic, or stainless steel is a vital step; also, using high-quality carbon or reverse osmosis filters can catch a significant percentage of micro-particles.

• Inhalation: In urban environments, people breathe in synthetic fibers from clothing and carpets. The main component of most clothing today is polyester, especially blankets and sheets, which come in direct contact with skin. Polyester can directly penetrate our body and cause immense harm.

• Dermal Contact: Some personal care products contain microbeads or plastic-based thickeners that can be absorbed through the skin. For this, we need to be very careful before purchasing our products; it is time we start reading product labels – simply flip the product and see the ingredients listed behind.

To What Extent is it Harmful?

While there is strong evidence that these plastics are present in the ovaries, researchers are still studying the long-term, population-wide effects on fertility. This is not a reason for panic, but it is a call for preventive action.

Pre-clinical models suggest that high levels of microplastics can reduce the ovarian reserve, which is the number of healthy eggs remaining with each passing year. In clinical settings, investigators are also beginning to explore whether the presence of these particles can explain why IVF treatments sometimes fail despite profiles being otherwise healthy. The evidence points to a dose-dependent risk, which means that if exposure is reduced now, it may protect future reproductive longevity.

The Path Forward: Advocacy and Awareness

This issue now sits at a critical intersection of environmental science and gynecology. There is a growing movement to go beyond viewing infertility as a purely medical issue and start seeing it as an environmental one. Furthermore, policy-level changes are needed to regulate the use of plastic in the food and beauty industries.

The presence of microplastics in the ovaries is a quiet, invisible threat, but it can be addressed through awareness and intentional living. By making small changes today, individuals are not just protecting their own health but also the biological integrity of generations to come.
