Study on Livestock Pollution Not Sound

Much has been said about cattle that increase carbon and methane levels in the atmosphere. Test were done on cattle in the European Union. Options were considered on how the emissions could be reduced. It was found that dairy and beef cattle contributed 60 per cent of pollution for the whole livestock industry.

Because little can be done about body waste emissions, efficiency factors were at the center of the study. Poor land use was the second highest factor in global greenhouse gas emissions after direct production. Pollution for wasted food followed inefficient use of land.

As usual the investigators did their calculations on how much pollution could be lessened if their advice was adopted by the livestock industry. It was estimated that the lowest impact would be a reduction of 12 per cent. Optimists in the group said 60 per cent.

Somehow consumption of meat was to be reduced. Just how this was to be done was not made clear. With people in developing countries adopting a taste for Western food potential meat consumption will probably increase, even if in the EU less is consumed.

It was found that changing to grain fed beef from grassland beef would decrease pollution. This is a questionable hypothesis considering more high quality grain would have be grown to feed more cattle. It is a very expensive way of producing beef as well. This finding was based on the assumption feed lots would be constructed on poor grazing land and good grazing land was left alone. This in itself would be a decrease in overall production efficiency. To reduce greenhouse gasses consumers would ultimately have to pay the price. Like the carbon tax, few countries will introduce a more costly meat production system purely because it will raise the price for consumers.

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...

Study of Tooth Enamel Indicates Neanderthal Diet Was Carnivorous

 A new study on Neanderthal dietary practices has just been published in the journal PNAS by researchers from the French National Centre for Scientific Research (CNRS) and several German scientific institutions. They were able to determine that a Neanderthal who lived in a cave on the Iberian Peninsula during the Middle Paleolithic period (50,000 years ago) ate exclusively carnivorous food using a newly developed method for studying the chemical signatures of ancient tooth enamel. This isn't the first study to find this, either. Despite this, it is a one-of-a-kind and significant discovery because it was made through the development of a novel analytical method that could be used to learn more about the diet and way of life of Neanderthals who lived in other parts of Eurasia in the distant past.   To investigate the diet and eating habits of Neanderthals, numerous research projects have been initiated. However, they have resulted in contradictory outcomes. The CNRS researchers...
