Global Warming and the Hidden Costs of Aviation

Global Warming and the Hidden Costs of Aviation

A recent study
reveals that aviation might pump 20% more carbon dioxide into the atmosphere by
2025 as previously estimated. Vexing is not the possibly underestimated figure;
but the fact that this study was only recently uncovered: As covered by The Independent
or Spiegel
Online, the British environmental association Aviation Environmental Federation now
presents the study on their webpage although it was already presented last
summer at an international conference in Barcelona. Jeff Gazzard, a spokesman
for the Aviation Environmental Federation, is convinced that this omission to
make the report publicly available was deliberate. The study contains alarming
piece of evidence that challenges the rather liberal approach to aviation of the
Kyoto Protocol: Only domestic aviation emissions are accounted for in a countries’
emissions totals, while emissions from international aviation are omitted (see Kyoto
Protocol, Decision 2/CP3).

Towards Ethical Foie Gras?

Often the source of our worries about eating animals and the basis of arguments against it seems to turn on the pain and suffering of the animal in question. With advances in biotechnology such as cloning and genetic manipulation it may at some point be possible to engineer animals that do not feel pain or suffer but still produce meat of the kind that we are accustomed to eating. Producing such animals on a large scale would significantly reduce the total amount of suffering and may enable us to eat meat with a clear conscience.

Sleeping policemen and garden sheds

Big Brother, it seems, has been asleep on the job.  Even though it is said that we in the UK are more subject to surveillance than any other society, peered at by cameras wherever we go about our innocent business, today’s headlines tell us that this intrusion is not even fulfilling its purpose of catching the people whose business is not so innocent.   The police apparently don’t like watching miles of boring video (and who can blame them?), so they don’t do it much,  and the massive investment in equipment has brought street crime in London down by only 3%.  Perhaps that is some consolation to people whose objections to surveillance are not just those of cost.  Even if the cameras are there, at least nobody is bothering to watch us.

The Apeman and the Scotsman: the slippery slope to humanzees

In the Scotsman this week there is an interview with a scientist who
has claimed that a loophole in the draft UK Human Fertilisation and
Embryology Bill is likely to lead to the creation of hybrid human-apes
or “humanzees”.

In essence this argument is a slippery slope objection to the proposed
changes in the powers of the UK regulatory authority for embryo and
fertilisation research.

The Choice to Have Artificial Blood: Less than the Best?

Controversy has erupted around whether experiments to test artificial blood should stop. Experimental blood substitutes raised the risk of heart attack and death, yet U.S. regulators allowed human testing to continue despite warning signs, says a scathing new report.

Blood substitutes, or artificial blood, could be stored for years without refrigeration, and be used in battlefield situations. It would carry no risk risk of infection with hepatitis or HIV. It would be an acceptable alternative to Jehovah’s Witnesses who refuse life saving blood transfusions.
In a new report, researchers pooled data from 16 separate studies of five different blood substitutes, involving over 3,700 patients. Researchers found a 30 percent higher risk of death overall for patients who received transfusions using the blood substitutes. The risk of heart attack was nearly tripled in the groups receiving blood substitutes.

“Experts speculate that hemoglobin in the blood substitutes scavenges nitric oxide from the blood, causing blood vessels to constrict and sticky platelets to build up. That increases the risk of heart attacks.”

Reverse Prostitution: cognitive biases and conditional cash transfers

Stuart Rennie writes a thoughtful blog on bioethics.net, Can
you buy changes in health behaviours? on how the World Bank backs an anti-AIDS experiment paying
young people to not contract sexually transmitted infections. The basic idea is not new, conditional cash transfer
programs in poor countries have had successes in improving health and education but applying it to sexual health moves it into more
controversial territory. Is there anything wrong with “reverse prostitution”?

Football screens and genes: Should genetic discrimination in sport be banned?

In the Guardian this weekend, it is reported that at least one UK football club has been contemplating using genetic tests to screen potential recruits,in the hope of identifying future star players. This comes only one day after legislation was passed in the US Senate prohibiting insurance companies and employers from using genetic information in hiring or insurance decisions.

New hope or false hope for vegetative patients?

A BBC documentary screening this evening on the ‘Inside Out’ program reports on what it describes as a breakthrough for patients in a vegetative state. It is based upon research by a group of neuroscientists in Cambridge, who have used sophisticated brain scans (functional magnetic resonance imaging (fMRI)) to look for signs of consciousness in patients who have previously been thought to be completely unaware of their surroundings.

The Dignity of the Carrot

What are you allowed to do to plants? At least in Switzerland you are not allowed to do research that deeply offend the dignity of plants. The Swiss federal Gene Technology Law stipulates that any scientific research should respect the "dignity of creation". All plant biotechnology grant applications must now state how they take plant dignity into consideration, confusing researchers.  The Federal Ethics Committee on Non-Human Biotechnology (ECNH) have issued some guidelines (pdf) which make the situation even more confusing. Neither humans nor plants are likely to be helped.
