Throughout North Dakota, little yellow flowers dot thousands of miles of roadsides. These canola plants, found along most major trucking routes, look harmless. But they are fueling a controversy: They prove that large numbers of genetically modified plants have escaped from farm fields and are now growing wild. About 80 percent of canola growing along roadsides in North Dakota contains genes that have been modified to make the plants resistant to common weed-killers.
If you can wade thru the technical reportage, the discussion section is rather fascinating (if you're into goat-breeeding...):
"A young descendant female is usually chosen according to its mother's and grandmother's family, taking into account its desirable productive traits as well as its abilities to endure the tough conditions.
Animals coming from the same family/pool will live together and move together more easily and naturally. Such “familial” behaviour is extremely beneficial to the cohesion of herds under free-ranging exploitation and especially during the movements on the pasturelands (transhumance).
On the contrary, introduction of new animals from other herds can induce significant disturbance in the herd movements by breaking the cohesion of the group. This practice of herders of course has the effect of reducing the genetic diversity...
The latest example of that persistence is legislation proposed in Washington state that would require genetically engineered foods, or food items that contain genetically engineered foods, to be labeled so consumers can make an informed choice about what they buy.
We levelled the land of forests and all life in them and carefully, mathematically plotted the land with big agriculture and big machinery to produce more for profit, nor more for nutrition. This is the result:
Agricultural fields can bear a stunning resemblance to linear, patchwork quilts – at least, when viewed from the air – as these 15 examples show!
And thus changes in popultion and farming.livestock practices change with clilmatic changes - as today:
"Cultivation was practiced in park savannas, an agroforestry system with protected wild fruit trees interspersed in the fields. During the first millennium AD, extensive cultivation with long fallow periods was practised. With the beginning of the second millennium AD, fallow periods became shorter and the influence of cattle herding on the vegetation increased, changing the composition of the woody vegetation. Decreasing precipitation and anthropogenic pressure eventually led to the much lower species diversity of the modern woody vegetation.
"The piece directly attacks the notion that carbon dioxide emissions are warming the globe, concluding with:
Every candidate should support rational measures to protect and improve our environment, but it makes no sense at all to back expensive programs that divert resources from real needs and are based on alarming but untenable claims of ‘incontrovertible’ evidence.
"Over the past four decades, coverage of food and agriculture has waned in the mainstream press at the same time as the impact of a more industrialized food system on public health has become increasingly severe,” said editorial boardmember Ruth Reichl. “Without detailed investigations into food and agriculture, our understanding of humanity’s impacts on the environment is incomplete and related policy changes ineffective.”
When Elanco studied the drug in pigs for its effectiveness, it reported that “no adverse effects were observed for any treatments.” But within a few years of Paylean’s approval, the company received hundreds of reports of sickened pigs from farmers and veterinarians, according to records from the FDA’s Center for Veterinary Medicine.
This is good news: tick-borne diseases are a major cause of weakness and death of livestock here in the tropics.
"Developing a vaccine to help control East Coast fever in Kenya could lead to a vaccine for Texas cattle fever, which is a problem for cattle producers in the United States, says ADRU entomologist Glen Scoles.
"That's because these parasites and the ticks that transmit them are so similar," Scoles explains. "Proteins we identify in one organism can also be studied in the other."
Many people say that giving smallholder farmers a stronger position in market chains is one of the best methods of helping them out of poverty, and that applies particularly to the neglected, orphaned, underused etc crops that are our bread and...
Modest changes are possible in response to increased populatons; changes in climates:
"The Results indicate that the most significant variables for the adoption of both of these conservation adoption are training and small ruminants holding. Variables such as education and perception of soil degradation are determinants only for the adoption of zaï technique...
