Ms. Mamitu was exceptionally lucky in that she was brought to a hospital here in Addis Ababa that offered free surgery by a saintly husband and wife pair of gynecologists from Australia, Reginald and Catherine Hamlin. Reg is now dead, while Catherine is the Mother Teresa of our time and is long overdue for a Nobel Peace Prize.
After that operation, 42 years ago, Ms. Mamitu was given a job making beds in the hospital. Then she began helping out during surgeries, and after a couple of years of watching she was asked by Dr. Reg Hamlin to cut some stitches. Eventually, Ms. Mamitu was routinely performing the entire fistula repair herself.
Over the decades, Ms. Mamitu has gradually become one of the most experienced fistula surgeons
. Gynecologists from around the world go to the Addis Ababa Fistula Hospital to train in fistula repair, and typically their teacher is Ms. Mamitu.

Wind turbines.. some antagonism to them being erected in beautiful Scottish Iles.
Myself, I think they look rather grand, dont amount to destruction.
Wouldnt like to live within earshot, the whooshing
is apparently crazy-making.
Gotta be some price to pay for electricity.
David Bellamy is very anti.
Whats important is to keep a clear picture of pollution.
Minor pollution is things like plastic bags and wind turbines. They 'spoil' the pristine look of a place. Major pollution is where land disturbance or chemicals degrade the biosystems in such a way that remediation is near impossible and bio-functions are disabled.
I would include swimming as a biofunction. A few plastic bags in a river are minor pollution, they dont by themselves prevent swimming in or drinking of the water. Their presence, however, is a fairly reliable sign that other, less visible, major pollutants are present. Things like sewage, oil, pesticides, herbicides, are likely to be there along with the visible plastic.
...In the 17th century we had 90,000 windmills in Britain... they say the new turbines kill 0.2 birds per year
birds dead beside windturbine Spain - the caption says removing dead birds. Its not clear that these 3 birds were killed at this spot, beneath this rather small turbine. The Bellamy freaks might be capable of exaggeration... or eagles might be especially vulnerable to these 120m blades...
It does seem a tad gross to erect over 130 in South Lewis
, Harris and North Uist National Scenic Area, even tho its mighty windy up there. Some say that tourists wont come to scenic sites blighted by towers. The transmission lines and pylons may be worse.

Who killed the big beasts in Australia long ago? Some, like Tim Flannery, have said it was people, others such as Judith Field say it was climate..PNAS..
a site at Cuddie Springs
in Western New South Wales, where both megafauna bones and the tools of people are found together..
Judith Field: It is really important because the dates from this site, the earliest record of cultural material is at 36,000 and the latest record of megafauna at the site is around about 28,000 to 30,000,,dissolved the bones and analysed them for their rare earth element contents. ..we took four horizons, two from the human or the archaeological levels and two from the pre-human record ..we can now argue that the dates from the sediment and the charcoal associated with the bones are actually contemporary with the bones and are 36,000 years old and 30,000 respectively.
Robyn Williams: So you are saying, on the basis of this one site, that you think the extinction of the megafauna was not caused by human beings but was caused by something else, presumably climate.
Robyn Williams: So they could have been living together for 10,000 or 20,000 years
Judith Field: Yes, so we’re talking a minimum time range of 15,000 and that’s really important ..there’s absolutely no evidence to connect people to extinction of the megafauna through habitat disruption..
They seemed to have disappeared round about 30,000 years ago and that’s about at the beginning of the last glacial maximum..
..one of the other interesting things about Cuddie Springs is in the 30,000 year horizon: not only do we have a diminished range of species and megafauna, we also have the first appearance of seed grinding stones
