Raising animals for food also includes feed-crop production which requires extensive water energy and chemical use as well as energy for transporting that feed live animals and animal products.
The total process for bringing such vast quantities of meat egg and dairy products to our plates comes at a substantial cost to the environment.
As a result of animal agriculture's impact on climate change organizations like the Natural resources Defense Council and the Sierra Club support eating more plant-based meals.
A Carnegie mellon University study found that eating plant-based meals even just one day a week reduces more greenhouse gases than eating exclusively local foods every day (a practice some people admirably
though mistakenly think leads to a major environmental impact due to the reduced travel miles to transport the food).
About a half-billion fewer animals are now being raised for food than just several years ago reducing animal agriculture's global impact.
With more than nine billion animals currently being raised for food in the United states each year if we all eschewed meat even one day a week
With more people sharing our mutual responsibility to reduce carbon footprints by shifting to plant-based meals we have reason to be hopeful for our planet's future.

UC San francisco researchers have completed experiments that overturn the scientific consensus on how the brain unger circuitgoverns eating.
and that the activation of Agrp neurons directly drives eating. But the new work shows that the Agrp-POMC circuit responds within seconds to the mere presence of food,
and that Agrp neurons motivate animals to seek and obtain food, rather than directly prompting them to consume it. o one would have predicted this.
It one of the most surprising results in the field in a long time, said Zachary Knight, Phd,
It has been known for 75 years that a region at the base of the brain called the hypothalamus exerts profound control over eating behavior.
which suppresses the desire to eat more food. Yiming Chen a graduate student in Knight lab, was expecting to build on the prevailing model of the hunger circuit
when he began experiments using newly developed fiber optic devices that allowed him to record Agrp-POMC activity in real time as mice were given food after a period of fasting. o one had recorded actually the activity of these neurons in a behaving mouse,
2015 online issue of Cell, just seconds after food was given to the mice, and before they had begun to eat,
if we gave a hungry mouse some food, then slowly, over many minutes, it would become satiated
If you simply give food to the mouse, almost immediately the neurons reversed their activation state.
and smells the food, before they even take a bite. The researchers found that the Agrp-POMC circuit could be quickly eset,
if the food were taken away. The magnitude of the transition from Agrp to POMC activity was correlated also directly with the palatability of the food offered:
peanut butter and chocolate, both of which are preferred much by mice over standard lab chow, caused a stronger and more rapid reversal of Agrp-POMC activity.
The Agrp-POMC responses also depended on the accessibility of the food. A slower and weaker transition was seen
if the mice were able detect the presence of peanut butter through smell, but couldn see the food.
These results show that, while slow, hunger-induced changes in hormones and nutrients activate Agrp neurons over the long term,
these neurons are inactivated rapidly by the sight and smell of food alone. A major implication of this discovery
Knight and Chen said, is that the function of Agrp neurons is to motivate hungry animals to seek
and find food, not to directly control eating behavior itself. The fact that more accessible and more palatable, energy-rich foods engage POMC neurons
and shut down Agrp activity more strongly suggests that the circuit also has nticipatoryaspects, by which these neurons predict the nutritional value of a forthcoming meal
and adjust their activity accordingly. Both of these roles of the Agrp-POMC circuit make sense,
if an animal has obtained successfully food, the most adaptive brain mechanism would suppress the motivation to continue searching;
likewise, since energy-dense foods alleviate hunger for longer periods, discovery of these foods should more strongly tamp down the hunger circuit
and the desire to seek additional nutrition. volution has made these neurons a key control point in the hunger circuit,
but it primarily to control the discovery of food, said Knight. t controlling the motivation to go out
and find food, not the intake of food itself. So far, clinical trials of drugs that target Agrp-related pathways have been said disappointing,
and he believes the new research may provide a new perspective on these efforts. hat probably drives obesity is the rewarding aspect of food.
When you want dessert after youe finished dinner it because it tastes good, and that doesn require hunger at all,
Knight said. inding that this circuitry primarily controls food discovery rather than eating changes our view of
not necessarily the decision to take the next bite of food. Other members of the Knight laboratory participating in the research were Yen-Chu Lin,
