2. Global warming
The mother of all apocalyptic fears
Increasing temperature causes dehydration and low BP
if night time temperatures do not drop, extreme heat can be a killer.
Poor air quality causes respiration problems like asthma
Increase in CO2 – plants fast growth – diseases
Vector remained dormant during winter gets activated with full power and cause
severe cholera
Anthrax , zombie disease , zika , tick borne illness , cholera , heat stroke
Other diseases on the rise due to extreme weather include hantavirus , schistosomiasis
, river blindness, and tuberculosis . It also causes the rise in hay fever, as when the
weather gets warmer there is a rise in pollen levels in the air.

5. Nuclear radiation
Radiation poisoning, also called "radiation sickness" or a "creeping dose“ due to
ionising radiation
Cause mutation to DNA resulting in cancer
if the exposure to the air comes after some time, radioactive material does not pose
a health risk
Radioactive cesium, on the other hand, can stay in the environment for more than a
century.
Bone marrow death , Prodromal syndrome , Gastrointestinal death , Central nervous
system death , pulmonary insufficiency ,Cancer induction In utero (within the womb)
effects on human development , Transgenerational genetic damage
Nuclear war of Japan – Dysentery ,Typhoid, Infectious hepatitis, Salmonellosis
,Cholera ,Meningococcal meningitis , Tuberculosis ,Diphtheria , Whooping cough,
Polio ,Pneumonia etc (40 rems)

7. Overpopulation
The fear of an overpopulated globe has been around since the
18th century, when Thomas Malthus predicted that population
growth would cause mass starvation and overtax the planet.
With the global population at 7 billion and counting, many
conservationists think population growth is one of the key
threats to the planet.
Not everyone agrees
Many think population growth will stabilize in the next 50 years,
and that humanity will innovate its way out of the negative
consequences of the overcrowding that does occur.

9. Mosquitos
Malaria is caused by a parasite that infects mosquitos. People get it from the bite of an
infected mosquito. Malaria caused about 627,000 deaths in 2012, according to WHO. Sub-
Saharan Africa took the brunt with 90 percent of all malaria deaths. Malaria is not
contagious.
Mosquito-borne diseases are probably the greatest threat to humans as they
include malaria, elephantiasis, Rift Valley fever, yellow fever, and dengue fever.
flooding and drought - Flooding creates more standing water for mosquitos to breed;
Measles is a contagious viral disease that can be prevented through immunization. In 2010,
it killed about 139,300 people around the world, according to the CDC.
These extended seasons are creating climates that are able to sustain vectors for longer
periods of time, allowing them to multiply rapidly, and also creating climates that are
allowing the introduction and survival of new vectors.[5]
No proper toilets and sanitation facilities

11. Microorganisms
Bacteria. These one-cell organisms are responsible for illnesses such as
strep throat, urinary tract infections and tuberculosis.
Viruses. Even smaller than bacteria, viruses cause a multitude of diseases
— ranging from the common cold to AIDS.
Fungi. Many skin diseases, such as ringworm and athlete's foot, are
caused by fungi. Other types of fungi can infect your lungs or nervous
system.
Parasites. Malaria is caused by a tiny parasite that is transmitted by a
mosquito bite. Other parasites may be transmitted to humans from
animal feces.
12. Food contamination
Another way disease-causing germs can infect you is through
contaminated food and water.
This mechanism of transmission allows germs to be spread to many
people through a single source.
E. coli, for example, is a bacterium present in or on certain foods — such
as undercooked hamburger or unpasteurized fruit juice.
The diseases caused due to food contamination may have a stronger
impact as the microbes acquire nutrition directly from the food source
13. Genetic disorder
A genetic disorder is an illness caused by changes in a person’s DNA resulting in
mutation.
Mutation can be due to environmental factors, such as cigarette smoke and exposure to
radiation, which cause changes in the DNA sequence.
These changes can affect the nitrogenous bases (A, C, G or T) or changing the
sequences of DNA or even chromosomes.
Example : Cancer, Down’s syndrome , diabetes
statistics 80% rare disease are due to genetical factor
14. Nutrition
Lack of nutrition causes malfunction of immunity
Radish and cabbage are anti cancerous
To be optimally healthy, we require adequate intake of water, fibre, and
phytonutrients.
Nutrient-rich foods include fresh vegetables, legumes, fruits, whole grains, nuts, and
seeds. Organic eggs and wild fish are also healthy, micronutrient-rich foods.
Prevent highly processed foods , soda, white flour, junk food , soft drinks.

17. Physical stress
It leads to scar tissue formation and joint dysfunction that may cause problems
with mobility and flexibility over the long term.
Leading obesity due to inactivity
Examples :wearing a backpack over only one shoulder, talking too long on the
phone while leaning to one side strains shoulder and neck
The way to avoid : stay physically comfortable ,Designing an optimal work
environment, taking regular breaks, and not taking asymmetrical position
during work
Bending the spine exerts pressure on lungs

20. Engineered disease
Natural diseases aren't the only ones to fear.
Earlier scientists engineered drugs against pathogens but in recent days
researchers are engineering diseases without a remedy for creating
biowar.
The results sparked fears that engineered deadly diseases could
inadvertently escape from the lab or be intentionally released, leading
to a global pandemic.
In 2011, the scientific community was outraged that researchers had
engineered a mutant version of the bird flu H5N1 that was transmissible
in ferrets and transmitted via the air.
