An angry resident, wrote the following regarding the despicable treatment of elderly patients at the Steve Biko state hospital.
“I had it with Steve Biko state Hospital at Casualty’s
They are one of the worst hospitals in Pretoria.
There is no care for any elderly person in that hospital, but there are elderly people abused in that hospital.
We sent this old lady two weeks a go with a stomach bug to Steve Biko
hospital, but with no bruises and this is how they sent her back to us.
Those bruises are from manual handling!
You are not fit to be called a nurse, you are the scum of the earth.”
In the spirit of Christmas, people have opened their hearts and wallets to help farm attack victims.
During a farm attack near Leeudoringstad on the farm Rietkuil Mr.
Thys Grobbelaar, (81) and his wife Rita, (76), Rita, were seriously
injured while their daughter Karin Nel (53) sustained injuries, and
their grandson, Joe Astle (24) was shot in the mouth.
Mr. Louis Meintjes, president of TAU SA has launched a fundraising
drive to assist Nel and her son Joe, when it emerged that they were in
state hospitals and not receiving appropriate treatment, due to the
shortage of doctors.
Joe was seriously injured. He was shot through the cheek, which
caused him to lose his teeth, his tongue was severely cut, and a bullet
remains lodged near his eye.
Within hours after the shocking incident, Mr. Meintjes, and TAU’s
regional chairman in the Western Region, Mr. Theunis Kruger set out to
assist the family. After the initial transport and transfer costs were
paid, Joe was transferred to a private hospital. Mr. Meintjies received
promises of support for this family and donations are expected from the
generosity of caring people. It is unsure at this stage what surgery and
treatment Joe will require and as there is no medical aid, the costs
can be extremely high.
The Anncron Clinic has offered a consultation and an anesthetist has
volunteered to assist. Several surgeons have indicated that they will
charge a reduced life in an attempt to save the young man’s life.
TAU’s vice president and chairman of the safety committee, Mr. Henry
Geldenhuys, said the fund will be ongoing and used for similar incidents
in the future. He called on the public to continue sending
contributions in order to register a national fund for victims.
Contributions for Mr. Joe Astle’s medical care can be deposited into the following account

A new species of dinosaur is described, on average, every ten days. As many as 31 species have already been reported this year and we can expect a few more before 2016 is over. Of course, figuring out what counts as a distinct species is a tricky problem. Palaeontologists are argumentative by nature, so getting any two of them to agree on a definitive list of species is probably impossible. But by anyone’s count, there were a lot of them – 700 or 800 that we know of, probably thousands in total. So how did the dinosaurs become so diverse?
First we need an idea of just how many dinosaur species there were. One study tried to estimate the total diversity of dinosaurs by using the species-area effect – the idea being that if we know how many species one small part of the Earth can support, we can extrapolate how many must have existed worldwide. These calculations suggest that at the end of the Mesozoic, 66m years ago, the standing diversity of dinosaurs – all the species alive at one point in time – was between 600 and 1,000 species.
This seems to be a reasonable estimate, in that if you counted up all of the living land mammals weighing more than 1kg (the size of the smallest dinosaurs) and then added the extinct species from the past 50,000 years, such as wooly mammoths, ground sloths, and giant kangaroos (correcting for losses to diversity caused by humans) you would end up with a similar figure.
However, this is just the number of species around at one point in time, and the dinosaurs were around for a very, very long time. Over the course of the Mesozoic, dinosaurs constantly evolved and went extinct. Doing some quick and rough estimates, and assuming 1,000 species of dinosaurs lived at any one time, and then that the species turned over every million years – that’s 160 times over the 160m-year reign of the dinosaurs – we end up with 160,000 species. Which is a lot of dinosaurs.
This is, of course, a very rough estimate. It depends on a lot of assumptions, such as how many different species the planet can support, and how quickly they evolve and go extinct. If we assume a lower standing diversity of 500 species and slower turnover, with species lasting 2m years, for example, we end up with around 50,000 species. On the other hand, perhaps standing diversity of 2,000 species is reasonable for the warm, lush, Mesozoic, and perhaps they only lasted just half a million years. That gives us over 500,000 species. So it seems reasonable to guess that there were between 50,000 and 500,000 species of dinosaurs – without including Mesozoic birds, which might double the diversity.

Why so many species, then? It comes down to three things. Dinosaurs were good at specialisation, localisation, and speciation.
Specialisation
Dinosaurs were specialists, and by specialising to exploit different niches, different species could coexist without competing. In western North America, the giant predator T. rex coexisted with little meat-eating dromaeosaurs. Enormous, long-necked sauropods browsed alongside horned ceratopsians, which grazed on ferns and flowers. There were smaller plant-eaters – pachycephalosaurs and ornithomimids – as well as heron-like fish eaters, and even anteater-like insectivores.
And within these niches, there was further specialisation. T. rex was large and had massive jaws but fairly stocky limbs, and was well-suited to preying on the slow-moving but heavily armed Triceratops. T. rex‘s cousin, Nanotyrannus, was smaller but had the lanky legs of a marathon runner, and probably chased down faster prey. This specialisation meant that - based on my recent studies of the fauna – as many as 25 dinosaurs could live side-by-side in one habitat.
Localisation
Localisation refers to how different places had different dinosaur species. Mongolia had one set of animals – tyrannosaurs, duckbills, and ostrich dinosaurs – inhabiting a lush delta that flowed through the middle of a desert. Just a few miles away, little horned dinosaurs and parrot-headed oviraptors inhabited the dune fields. Dinosaurs also show differences across continents, with different species inhabiting different parts of North America, for example. Between continents, the differences are even more extreme. During the Late Cretaceous, North America and Asia were dominated by tyrannosaurs, duckbilled dinosaurs, and horned dinosaurs. But Africa and South America, cut off by oceans for tens of millions of years, had an entirely different set of species. Instead of tyrannosaurs, the horned abelisaurs were top predators. Instead of duckbills, the long-necked titanosaurs were the dominant plant eaters.
Speciation
Dinosaurs evolved new species with remarkable speed. Radioactive dating has made it possible to date the rocks containing dinosaur fossils, and from that, to estimate how long dinosaur species lasted. The rocks forming the Hell Creek Formation in Montana, for example, were deposited over a period of around 2m years. At the bottom of these strata, we have one species- Triceratops horridus, and at the top, we have a second Triceratops prorsusevolving from the first.
This implies that a species lasts a million years or less – a short time, at least in geological terms. Studies of other formations, and other horned dinosaurs, tend to suggest that other species were similarly short-lived. In the badlands of Dinosaur Park in Canada, we can find fossils that show three different sets of dinosaur – the first replaced by the second, the second by the third – evolving in 2m years. Dinosaurs evolved rapidly, driven by shifts in the planet’s seas, climates, and continents, and also the evolution of other dinosaurs. And if they didn’t, they went extinct.
We’ll never know exactly how many dinosaurs existed. It’s so rare for an animal to fossilise and be preserved that many tens of thousands of species, maybe hundreds of thousands, are probably lost to us forever. And yet the remarkable thing is that the pace of dinosaur discovery has actually increased over the years. Most of the species that have ever lived are lost, but we have thousands left to find.
This horrific scene witnessed at Blythedale Beach forces any
patriotic South African to involuntarily vomit, just a little, in your
own mouth.
The way we mistreat our beautiful beaches/coasts reflects a hurtful
lack of respect we have for ourselves as Africans. Ma’ Africa stirs
angrily at this abuse of her goodness.
No
doubt, this is an omen. It reveals the disturbing trend of the moral
character of our people and the challenges ahead as a country. We
suffered for our liberation, and now we vomit, urinate, shit and litter
on the very shores of the African land that has embraced us.
So much for the dignity, our parents fought for.
What is the mindset of these feral people who feel empowered to
behave this way? Are they just carefree? Are they embittered at life?
Are they oblivious to their behavior? Are they brazenly setting the bar
for what is the new norm in South Africa? Either way, it is clear their
descent into wretchedness is disturbing.
Close to 6000 people moved into the village just after 22:00 last night. No police support.
Emergency services could not gain access to attend to a stabbing.
Three bodies were found on the beach, abandoned, this juxtaposed with
early morning sex throes reverberating from the bushes nearby.
These bodies lie cold, like the future, our children can expect
should we continue to let our government silently sponsor the
destruction of moral values and the lack of accountability in our ailing
country.
Of course, there are those who will say that littering occurs in
every country and is a sore issue in many cultures …but why can’t we be
better I ask? Where is our pride?

Has South Africa’s entitlement culture resulted in people getting used to living with trash?
After all, someone is getting paid to pick up after you, right? Or,
even worse …my parents picked up rubbish under apartheid, so I detest
doing that now out of resentment.
Let’s
be respectful and be responsible stewards of our country, and treat our
environment like we would like to be treated ourselves.
