Brain-Eating Amoeba and Global Warming

Jack Dikian
August 2011

We heard of the second death of a 9-year-old Virginia boy after contracting an infection linked to a water-borne "brain-eating amoeba" (although not a true amoeba, the organism is often referred to as an amoeba for convenience). According to the Centres for Disease Control and Prevention (CDC) a 16-year-old Floridan also died not long after swimming in St. John's River a month ago.

Autopsy results confirmed the cause of death as an inflammation of the brain and its lining. The CDC reports of 32 infections, known as Naegleria fowleri between 2001 and 2010 and several hundred cases worldwide since its discovery in Australia in 19651. The Science Discovery Channel2 identifies Naegleria fowleri as the fifth in the top-ten infectious diseases – amongst Rabies, Ebola, and Polio.


The microscopic organism that's found in freshwater lakes, rivers, and hot springs enters the human body via the nose. From there it travels a short distance of a few inches to the brain where it attacks brain tissue.


Whilst the Naegleria fowleri infection has been reported around the world, most of the cases in the United States have been linked to freshwater sources in the southern states. The amoeba proliferates in stagnant freshwater lakes and ponds during hot weather. Because this is a heat-loving amoeba some have even connected this to global warming – claiming reasonably that as water temperatures go up, we may see an increase of these cases.


Onset symptoms of infection start within 2 weeks after exposure. The initial symptoms include, but are not limited to changes in taste and smell, also headache, fever, nausea, vomiting, and stiff neck. Secondary symptoms include confusion, hallucinations, lack of attention, ataxia, and seizures. After the start of symptoms, the disease progresses rapidly 3 to 7 days, with death occurring from 7 to 14 days.3

Headlights Against Carbon Tax

August 2011

Over the years people (sometimes many hundreds of thousands of people) all over the world have taken part in protests against the government of the time, rallied for a cause, marched to right a wrong, and other. Many don’t necessarily identify themselves as activists but have reached a point where they believe enough is enough.

Most people protest because they are angry about the government’s lack of performance, broken promises, and/or how the government how the government is managing various economic issues, such as services like water and electricity, jobs, and housing.

Certainly here in Australia we have had our share of protests. Consider for example the Eureka Rebellion, 2010 Australian gender equality rallies, Aboriginal Tent Embassy, Franklin Dam. Fortunately most of protests in Australia have been largely peaceful and lawful.

Today (August 2011) saw the first anniversary of when the Australian Prime Minister Julia Gillard declared, “there will be no Carbon tax under the government I lead”. The National Road Freighters Association organized a convoy recruiting vehicles as they made their way through towns en route to Canberra. The protest was initially instigated by the live export ban to Indonesia but grew into a 'Convoy of No Confidence'. Motorists who weren’t able to travel to Canberra quickly joined the rally by turning their headlights on in support of those able to join the protest in Canberra.
