World Environmental Health Day 2023's theme

World Environmental Health Day has a specific theme that was developed by the International Federation of Environmental Health (IHEF). The theme has been chosen to align with the UN Sustainable Development Goals.


"Global Environmental Public Health: Standing up to protect everyone's Health each and every day" is the topic for World Environmental Health Day in 2023.
The Importance of Environmental Health
  • Environmental health is a critical aspect of public health and has a profound impact on the well-being of individuals, communities, and the planet as a whole. It encompasses the study and management of the environmental factors that can affect human health, both directly and indirectly. Here are several reasons why environmental health is of utmost importance:
  • Human Health: Our entire health is significantly influenced by the environment in which we live. Numerous health issues, including respiratory infections, waterborne illnesses, and exposure to hazardous substances, can result from poor environmental conditions. In order to prevent these health difficulties and raise people's quality of life, it is crucial to address environmental health issues.
  • Preventing Diseases: Many infectious diseases are closely linked to environmental factors. For example, inadequate sanitation and contaminated water sources can lead to the spread of diseases like cholera and dysentery. Proper management of environmental conditions, such as clean water and proper waste disposal, is crucial for preventing the outbreak of these diseases.
  • Climate Change::Climate change is a serious concern to human health, and it is directly related to environmental health. Climate change is associated with increased temperatures, severe weather, and altered disease patterns. To reduce the health hazards brought on by climate change, it is crucial to address environmental issues, such as lowering greenhouse gas emissions.
  • Biodiversity and Ecosystem Services: Humans depend on healthy ecosystems to provide them with services like clean air and water, crop pollination, and control over disease vectors. These ecosystem services can be disrupted by environmental deterioration, such as habitat loss and deforestation, which can have detrimental effects on human health.
  • Food Safety: Environmental health and the safety of our food supply are intimately related. Food crops and cattle can become contaminated as a result of contaminated soil, water, and air. A steady food supply and the prevention of foodborne illnesses depend on the safety of our food sources.
  • Vulnerable Populations: Environmental health problems frequently have a disproportionately negative impact on vulnerable groups, including children, the elderly, and low-income communities. It is critical to address environmental inequities since these groups may have inadequate access to healthcare and resources to protect themselves from environmental risks.
  • Global Health: Environmental health is a universal problem that crosses national boundaries. Climate change, infectious illnesses, and pollution can all have significant global effects. To tackle these issues and safeguard the health of everyone on the planet, global cooperation is required.
  • Economic Impact: Healthcare costs, lost productivity, and damage to infrastructure are just a few of the considerable financial implications associated with poor environmental health. Long-term cost reductions and economic advantages can result from investing in environmental health measures.
  • Sustainable Development: Sustainable development and environmental health are closely related ideas. To ensure that future generations can meet their requirements without endangering the health of the world, it is crucial to strike a balance between economic growth, environmental conservation, and human well-being.
Key Environmental Health Challenges

Air Pollution: Poor air quality is a significant concern, with millions of people worldwide exposed to harmful pollutants that can lead to respiratory problems, heart disease, and even premature death. Efforts to reduce emissions from vehicles, factories, and power plants are vital for improving air quality. Household air pollution was responsible for an estimated 3.2 million deaths per year in 2020, including over 237,000 deaths of children under the age of 5. The combined effects of ambient air pollution and household air pollution are associated with 6.7 million premature deaths annually.

Water Quality: Water sanitation and purification initiatives are crucial because contaminated water sources can result in waterborne diseases, despite the fact that many people still do not have access to clean and safe drinking water, which is a fundamental human right. According To the World Health Organisation in 2021, over 2 billion people live in water-stressed countries, which is expected to be exacerbated in some regions as a result of climate change and population growth. In 2022, globally, at least 1.7 billion people use a drinking water source contaminated with faeces. In 2022, 73% of the global population (6 billion people) used a safely managed drinking water service – that is, one located on premises, available when needed, and free from contamination.

Climate Change: The ongoing climate change catastrophe is having a significant impact on both the environment and human health. The physical and emotional well-being of people is seriously threatened by climate change, severe weather, and ecosystem changes.

Biodiversity Loss: The decline in biodiversity has an influence on human health in addition to ecosystems. For the development of novel medications, disease prevention, and food security, a wide variety of species is necessary.

Hazardous Chemicals: Long-term health effects from exposure to dangerous chemicals in our environment are possible. Stricter rules and proper chemical management are essential for lowering these dangers.

Taking Action on World Environmental Health Day

World Environmental Health Day provides an opportunity for individuals, communities, and governments to take action and make a positive impact on our environment and health. Here are some ways to get involved:

Education and Awareness: Start by becoming knowledgeable about environmental health issues for both you and others. To increase awareness in your community, disseminate knowledge through workshops, conferences, and social media.

Sustainable Practices: Use sustainable lifestyle choices in your regular activities, such as recycling, saving water and electricity, and using the bus or carpooling to reduce air pollution.

Support Clean Energy: Promote the use of sustainable and clean energy. Support laws and programs that encourage the use of hydroelectric, wind, and solar energy.

Reduce Plastic Use: Use reusable containers, bottles, and bags to limit your use of plastic. A serious threat to the environment's health is plastic pollution.

Community Involvement: Participate in neighbourhood environmental projects including planting trees, cleanup efforts, and community gardens. These activities can improve your community's well-being.

Advocate for Policy Change: Encourage your government to implement and uphold laws that safeguard the environment and the general public's health. Join environmental advocacy organizations and communicate with decision-makers. This reminded us on World Environmental Health Day that our actions have a significant impact on the environment and our health. It is a call to action for people, groups, and organizations to work together to address the serious environmental health issues we are currently facing. We can create the conditions for a healthier, more sustainable future for everyone if we take action to decrease pollution, save resources, and protect biodiversity. Keep in mind that every decision matters, and that by working together, we can significantly impact the preservation of our world for future generations.
