World Earth Day: Why a Healthy Planet Is the Foundation of Human Health

Every April 22, the world unites —not just to reflect, but to renew. Earth Day ignites a sense of purpose—reminding us that the path to vibrant human health begins with our unwavering commitment to nurture our planet.

This year's theme, "Our Power, Our Planet," is a call to act—individually, institutionally, urgently. At Meril, it resonates far beyond a tagline. As an organization that believes good health starts with a healthy environment, Earth Day isn’t just another date on the calendar — it guides how we think and act.

The impact of environmental damage isn’t distant or theoretical anymore. It’s already affecting people’s health in visible and subtle ways.

• Diseases carried by insects are appearing in regions where they were once unknown, exposing communities with little natural protection.^[1]

• Heatwaves are becoming more frequent and severe, placing additional strain on vulnerable groups such as children, older adults, and those with existing health conditions.

• Changes in soil quality and unpredictable rainfall are gradually affecting both the availability and the nutritional value of the food we rely on.

This isn’t about future scenarios. These changes are already happening, across the world, shaping lives in real time.

Pollution doesn’t always announce itself. It builds up quietly—in the air we breathe, the water we depend on, and even the food we eat—often long before we notice the damage.

The quality of air in our cities has a direct impact on heart and lung health over time. Clean water, still out of reach for many, influences hygiene, nutrition, and the spread of disease simultaneously. And then there are microplastics—now found in human blood—raising questions that science is only just beginning to explore.^[2]

At Meril, there’s a simple but important question behind what we do: how can patient outcomes be improved while remaining mindful of the world those patients live in? 

That thinking shows up in day-to-day decisions.

• Expanding the use of solar energy across facilities to generate cleaner power

• Working toward planting 3 million trees by 2030, with a focus on restoring ecosystems alongside communities

• Putting systems in place to conserve water and reduce overall usage

• Developing green campuses that support biodiversity and local habitats

• Moving toward more responsible packaging, with circularity in mind

Sustainability here is part of how things are designed and done.

Organizations do play a large role, but individual choices matter more than we sometimes think. In many cases, it comes down to small, consistent habits:

• Walk, cycle, or use public transport when possible—it benefits both personal health and air quality.

• Cut back on single-use plastics; carry alternatives where you can

• Include more plant-based meals, even if it’s just a few times a week.

• Fix leaks and avoid wasting water.

• Return unused or expired medicines through proper pharmacy programs.

These aren’t drastic changes. Start today—one habit at a time. Consistent action will strengthen personal well-being and fuel a healthier planet.

Earth Day is a chance to pause and recognize something simple: the planet isn’t separate from us—it sustains us. The air, water, and climate we depend on shape every aspect of health.

This year’s theme, “Our Power, Our Planet,” reminds us that responsibility is shared. Progress depends on the choices made at work, within communities, and at home.

Small, intentional actions taken today will shape the future that generations inherit tomorrow. Whether through innovation, conservation, or daily habits, each step contributes to a healthier, more resilient world.

Because a healthy planet is not an added benefit—it is the foundation on which everything else begins.
