A child’s immunity needs to develop naturally
Vaccines actual y strengthen the immune system. Because they
introduce a weakened form of a virus into the body, vaccines help the
immune system by teaching it to identify and defend against infections
in the future. Children need to be vaccinated at a young age because that’s
when their immune system is the most susceptible. However, young
and old people alike need an immune system boost with a vaccine.

Vaccines contain toxic chemicals such as
mercury, aluminum or formaldehyde
While some vaccines contain potential y toxic substances, these
chemicals become toxic to the human body only when present at
certain levels. All vaccine ingredients are present in very low quantities,
and they don’t cause any harm in these small amounts. Mercury used
to be present in negligible amounts, but due to public outrage, it was
removed entirely from vaccines in 2001. A vaccine contains only 0.1
mg of formaldehyde, which is far less than the 500 mg the human body
makes every day for DNA synthesis.

A baby’s immune system can’t handle that
many vaccines
On any given day, a child will fight between 2,000 and 6,000 immune
challenges, which is far more than the number of antigens or reactive
particles in all of the 14 scheduled vaccines combined. Even if a baby
were to take them all at once, the vaccines would only slightly tax their
immune system -- less than 0.1% of its total capacity. Immunizations
are negligible in comparison to the countless bacteria and viruses that
a baby fights off every day.
4
The side effects aren’t worth it
Children have been vaccinated for decades and, despite what you
may have read, there is no one reputable source or credible study
linking immunization to long-term health problems. Significant side
effects are extremely rare (around one in a million cases), and are far
outweighed by the advantages.
. . .
Some vaccines can lead to mild symptoms resembling
the infections they are designed to prevent.
In the very rare cases where these symptoms occur,
the person’s immune response is to the vaccine’s
content, not the disease itself.

Hygiene and better sanitation are responsible
for the drop in infections, not vaccines
While these socioeconomic elements are important and significantly
lowered the population’s death rate, their effect on infectious diseases
isn’t nearly as great as that of vaccines. It was a vaccine, not running
water and soap, that eradicated polio. The immune response is to the
vaccine’s content, not the disease itself.
Vaccines infect children with the diseases
6
they’re supposedly trying to prevent
There is only one instance in which a vaccine was shown to cause
disease -- the Oral Polio Vaccine (OPV), which in some cases caused
patients to develop poliomyelitis due to the live virus being used. OPV
is no longer used and was replaced by an injection that doesn’t contain
live viruses.
Vaccines are a conspiracy designed by big
7
pharma for profit
Pharmaceutical companies make money from vaccines, like all
companies do from their products. Compared with drugs that require
daily doses, vaccines are only administered once a year or once in a
lifetime, which offers far less economic incentive than other drugs.
Besides, if more people don’t use vaccines and get sick, that would make
pharma companies even richer.

Vaccines are designed to protect you but are just as important for
protecting those around you -- especial y vulnerable groups like the
elderly or those who can’t be vaccinated due to medical considerations.
By choosing not to vaccinate, you put others at risk, which interferes
with their right to a healthy life. Even if it’s just for yourself, vaccines
aren’t nearly unique in this -- laws also mandate wearing seatbelts, for
instance, or local smoking bans.
9
Vaccines are no longer required -- there aren’t
any more diseases left to fight!
The Polio virus (like many others) is still around and could easily
start re-infecting unprotected individuals when re-introduced to the
country. A better example is measles, which was very rare in the United
States until outbreaks occurred as a result of Americans traveling to
countries where the disease remained widespread.
When there are adequate vaccination rates, most types of outbreaks
can be prevented.

Vaccines cause autism
We’ve already gone through this, but it deserves another mention.
Hopeful y, this long-disproven idea will eventual y go away.

risky and may seriously harm you.
Many people use so-called detox diets to cleanse their bodies of
toxins -- or so they think.
There’s only one real type of detox: the kind performed in hospitals in
order to treat a person suffering from dangerous levels of drugs, alcohol,
or poison. In any other context, ‘detox’ refers to unproven alternative
medicine hacks like diets, supplements, or colon irrigations meant to
flush toxins out of your system.
Essential y, detoxin
g is supposed to remove ‘toxic’ things that have
accumulated in the body. Needless to say, there’s no scientific evidence
behind these practices. The supposed toxins are never specifical y
named, and instead are general y referred to as “poisons”, “pol utants”,
and “toxins”. Like true snake oil salesmen, detox practitioners like to
use vague statements to trick people.
Detox programs may involve a variety of approaches, such as:
• Fasting;
• Exclusively consuming juice or some other liquid for days at a
time;
• Eating a very restricted selection of foods;
• Using various dietary supplements or other commercial products;
• Cleansing the colon (lower intestinal tract) with enemas,
laxatives, or colon hydrotherapy (also called “colonic irrigation”
or “colonics”);
• Combining several of these together, or utilizing other approaches.

You can find of articles online on all sorts of detoxes[34]. Some are relatively benign, such as the “carrot juice cleanse”, but others are
downright dangerous. Many programs permit no food, just tea and
lemonade, and sometimes including more exotic ingredients like maple
syrup and cayenne pepper.

these diets remove any toxins.
The only thing that they achieve is weight loss but that’s, of course, to
be expected when a person stops eating food. Even the weight loss bit is
a smokescreen, as detox helps you lose fluids, not fat[35].
In fact, using this diet can harm you in the long run because it robs
the body of important nutrients like protein, vitamins, and minerals.
According to the Harvard Medical School[36], the laxative component of the diet can lead to dehydration and electrolyte loss as well as an
impaired bowel function. Other side effects[37] may include fatigue, nausea, and dizziness over the short-term, and loss of muscle mass and
a heightened risk of heart attack in the long-run.
Most other popular body cleanses make similar promises and follow
more or less the same low-calorie, nutrient-poor diets. It’s important to
understand why this is happening, and that just because you’re losing
weight doesn’t mean it’s good for your body.
. . .
A lot of people who fall for detoxing are drawn in by
the mirage of healthy living. They see detoxing as a
quick fix, a miracle cure, or a much-needed reset
that will let them feel refreshed and anew.

Want a detox? Just ask your liver
Good news! You already have the perfect al y against toxins: your
body! Your body is an expert at getting rid of waste, and it’s doing fine
whether you’re doing a detox or not. The key is your liver.
Out of the hundreds of functions your liver performs, ensuring
toxins are safely removed from your blood is one of its most critical
jobs. Your body is exposed to potential y toxic chemicals (only toxic
if their concentration in the blood passes a certain threshold) when
coming into contact with certain environmental pol utants such as
pesticides, but also as a result of normal digestion. For instance, when we
digest protein, ammonia is released as a byproduct, which is eliminated
through urine. Any wastes your liver cannot use are converted and
either carried out by bile into your small intestine or by the blood to
your kidneys.
But the truth is that these toxins don’t build up in your liver, kidneys,
or any other part of your body, and if they did, you’d be in major trouble
-- and no detox program would be able to help. It’s basic biology.
In 2009, a group of young British scientists -- part of the pro-
science charity Sense About Science -- compiled the
“Detox Dossier” [38].
This was an investigation into “some of the many products,
special diets, tonics and supplements which are widely
promoted as being able to ‘detox’ you after the festive season.”
The authors of the report felt the public was being duped
by dodgy science claims such as detox so they contacted
the manufacturers of 15 detox products. What did these
producers mean by detox?
None had any clue!
48
Detox
A fad
There is not one credible scientific paper that endorses a detox
product, diet, or remedy. A review recently published in the Journal of
Human Nutrition and Dietetics[39] sums it up nicely:
“To the best of our knowledge, no rigorous clinical investigations of
detox diets have been conducted. The handful of studies that have been
published suffer from significant methodological limitations including
small sample sizes, sampling bias, lack of control groups, reliance on
self-report and qualitative rather than quantitative measurements.”
That being said, of course a healthy diet will help your body function
better -- but this is no detox. Ultimately, the best ‘detox’ is not smoking,
exercising regularly, and enjoying a healthy balanced diet that is rich in
fruits and vegetables.

Climate Change Denial
Climate change
The Earth’s climate is changing, this change is unnatural, and we humans
are causing it. That is the extent of what we know so far.
Lastly, it’s time to address a problem much more complex than
what we’ve dealt with so far: climate change. Sure enough, a counter
movement has also emerged: climate change denial. Groups of people
(often with vested interests) are spreading unwarranted doubts, opposing
the overwhelming scientific evidence, denying that this change is
happening and/or that humans are responsible. The evidence linking
climate change to human activity is so clear it resembles the relationship
between smoking and cancer risk -- in fact, there is more statistical
relevance linking human activity to climate change than smoking to
cancer. Therefore, climate change denial can only be regarded as a
pseudoscience[40].
r /> Surely Earth’s climate has changed
before?!
The Earth is no stranger to climate change. From the narrowly-
avoided “snowball Earth” 650 million years ago [41] to the ice-less Cretaceous period, our blue dot has had its fair share of changes. But
our era is unlike any other -- there was no dramatic event or natural
phenomenon like a volcano eruption that can explain this change -- it’s
simply happening too fast.
Natural changes on this scale tend to happen in geological time, on a
scale of tens of thousands of years to millions of years -- whereas most
of the changes we’ve seen have happened in the past 30 years.
52
Climate Change Denial
We’ve also observed far more than a correlation -- the causation
mechanism is also pretty clear: the large amount of greenhouse gases
we’re outputting, particularly CO2, is what’s causing climate change.
There have been tens of thousands of studies on this, with only a handful
(often dubious works) casting any doubt on the conclusion that climate
change is, indeed, happening[42].

happening?
If you were to pile up all these studies, which tend to have around
20 pages, you’d end up with a pretty impressive mountain of paperwork
supporting climate change[42].
Jokes aside, there are very clear indicators that climate change is
happening, and that it is linked to human activities:
a) temperatures are rising: this[43][44] is the most direct piece of evidence.
The planet’s average temperature has risen by about 1.62 degrees
Fahrenheit (0.9 degrees Celsius) since the late 19th century, when the
Industrial Revolution kicked in. This doesn’t mean that every single
place is warmer than it used to be, or that every single day is warmer
than usual -- it’s important to make the distinction between weather
(atmospheric conditions over a short period of time) and climate (an
“average” of the weather over a longer period of time).
Just because we occasional y have cold days doesn’t mean climate change
isn’t happening. On a large scale, the Earth is definitely heating up.
b) oceans are heating up: it’s not just the atmosphere or the land that’s heating up -- global waters are absorbing much of this heat as wel [45].
