Somehow, these changes are affecting human health because for few years we are witnessing the growth in the new and more acute diseases which are risky for human health. But we are still neglecting all these changes and continuously carrying on our actions that degrade the environment. Consequently, the world is now dealing with the Covid-19 virus that has disrupted all the activities across the world since its outbreak.

So, WHO released a manifesto on May 26, 2020 for a healthy recovery from COVID-19. This manifesto is based on six key ideas and its main purpose is to seize the moment. This is so because the world is going through a worst recession with loss in business, jobs and incomes due to pandemic. This has brought an irreparable damage to the achievement goal of Sustainable Development. However, this pandemic also helped us find out the difficulties and inequalities, specially in the existing healthcare in the world. So, the World Environmental Health Day is being celebrated not only to spread the awareness about the factors that are related to health problems but also to encourage people to find out the solution of these problems to live a peaceful and healthy life.

What is Environmental Health?

Environmental health refers to interrelationship between the environment and living beings. Everything that we observe in our surroundings is known as environment. It includes all living things, non living things, natural things and man-made things. Environmental health is the branch of public health that describes the relationships between people and their environment. The clean environment plays an essential role for the survival of the human beings. Clearer environment promotes healthier life of people. Changes in the natural or artificial environment can affect human health.

For past few years, development and advancement in the technologies have created an artificial environment that humans are using to fulfill their wishes. But like every coin has two faces, this progress has a negative effect on environment and human health. Biggest example of this is the outbreak of the Covid-19 pandemic. According to World Health Organistion (WHO), healthier environment could prevent around one quarter of the global burden of diseases.

What we can do to protect Environmental Health?

Most of the changes that are occurring in the environment are triggered by the human activities. However, there can be some other external factors causing environmental changes. The changing of seasons, temperature in day and night, etc. are some phenomenon that occurs naturally but they can be disturbed by the interference of humans. The increasing global warming, depletion of ozone layer, birth of several new diseases, increasing pollution, etc. are the results of human activities that are affecting the environmental health adversely. So, it is very important to spread the awareness about it by observing World Environmental Health Day. We must be aware of how humans’ health and environment are interconnected and the causes that are affecting environmental health. This day also encourages people to find solutions of the problems related to the health and environment.  

The issues we are facing now are tough and that’s why they need to be taken care. The local authorities should promote environmental care by organizing different activities that improves environmental health. This pandemic also taught us the value of physical fitness, while it also make us understand the importance of hygiene, sanitizations etc. One doesn’t have to be an expert or a millionaire to save the earth. At an individual level, we can keep our environment clean by keeping our neighborhood tidy, avoiding pollutants emitting vehicles, using lesser plastic materials, using eco-friendly products, gardening and planting and most importantly following the Covid protocols.


We need a healthy and supportive environment around us for good health. People who do not care about the environment, simply do not understand how important it is to all of us. Therefore, nature conservation is very essential if we want to live in a healthy environment. If today we save our present then only we can shape our future. With the establishment of this day, environmental health awareness is increasing among the people around the world and they are coming together to fight for a healthy future. On World Environmental Health Day 2021, let’s make a commitment to take a step forward to take care of our health by keeping our environment safe.
