Understanding the consequences of natural and man-made vulnerabilities and hazards is essential to protecting human health and environmental systems. This entails analyzing and assessing how ecological systems affect the spread of diseases as well as how chemicals produced by humans affect human health or animals. Everything from controlling the usage of pesticides to the caliber of the drywall used in construction might be included.
It is a field of medicine that is attracting more and more attention on a global scale as more studies show that environmental health impacts not only individuals but also local economies and the cost of public health care. Environmental health, in its simplest form, is the study of how environmental influences can negatively impact human health and how to recognize and manage such effects.
Environmental hazard types
Every single day, environmental threats un sustainable development present themselves to humans in different ways. Let’s divide them into the following four groups to better understand environmental health:
1. Biological dangers
The relationships between organisms in their environment give rise to biological dangers. Bacteria, viruses, fungi, spores, pathogenic microorganisms, tuberculosis, malaria, and other species are a few examples of biological risks.
We refer to these illnesses as infectious diseases when they are spread between two or more species. The actual cause of these viruses and diseases in people is that they are being infected by other organisms, which is a normal but dangerous process.
2. Risks to health
These are physical events that take place naturally in the environment, such as landslides, blizzards, tornadoes, droughts, earthquakes, volcanoes, and earthquakes. Not all physical risks are seen as concealed happenings.
For instance, some things, like UV radiation, happen every day in the open. Ultraviolet radiation is seen as dangerous since excessive exposure causes DNA damage and leads to health issues in people like skin cancer and cataracts.
3. Risks from chemicals
They might be either naturally occurring or man-made in ecological systems. Mercury and lead, which are regarded as heavy metals, are examples of chemical risks that occur naturally. Numerous synthetic compounds that people create, such as insecticides, plastics, and disinfectants, are included in the category of “human-made chemical dangers.”
Some united nations SDGs even produce environmentally dangerous natural compounds, such as the substances in dairy and peanuts that cause allergic reactions in people.
4. Cultural risks
They are occasionally called social dangers. Your location, behavioral choices, profession, and socioeconomic level all contribute to them. Cultural risks include things like smoking cigarettes, which is bad for human health. Smoking cigarettes is regarded as a behavior choice.
According to your unsustainable development, living in a neighborhood where crime is prevalent is considered a risk. Your diet, exercise routine, and primary mode of transportation all have an equal impact on both your general health and the natural system around you.
5. Accommodation and Travel
Environmental health also considers the caliber and state of housing and transportation. The current emphasis on getting rid of lead and asbestos from buildings is one instance of how environmental health has changed and shaped the construction united nations SDG.
If a local community doesn’t have access to any public transportation or lacks the infrastructure to make use of nearby possibilities and services, transportation could become a problem for environmental health.
