Excessive use of antibiotics in animals has caused a resistance to those drugs among humans.
Nitrogen fertilisers have contaminated our water system and atmosphere with dangerous nitrates.
Life Cycle Analysis figures indicates that cow and sheeps are the least eco friendly meat that contribute to greenhouse gases emission.
Grass eaters are producing huge amount of methane, which is 25 times more potent greenhouse gas than carbon dioxide.
We have our suspicions of the industrialisation of farming, and the scandals in the industry.
Demand for meat consumption increased and so the amount of land used to create food to feed the farm animals with grains and oilseeds.
This approach has been considered to directly have affect on huge global inequalities and why so many see meat as main issue for climate justice.
Cassidy stated that if the growing food was exclusively for direct human consumption it could feed additional 4 billions people.
Meat consumption is potentially a barrier to solving hunger and malnutrition, the impact of industrially produced meat has an impact on lives of the poorest.
What are the alternatives?
One way is to introduce more of game meat, wide animals to our kitchens. Meat that used to be enjoyed by gentry, is not getting some traction.
We could argue that the most ethical are truly wide game such as rabbit, squirrel, pigeon,venison (some). Managed are pheasant and partridge.
The meat is not only sustainable but also healthy.
Venison is the leanest red meat, low in saturated fat, while high in protein, rich in iron packed with vitamin B which can lower the risk of strokes and heart attacks. It isn't overly gamey, so you could swap it for a beef.
If we cooked game meat more often we could reduce the pressure off farmed animals.
Boar is source of thiamine, a vitamin that aids muscle and heart function.
Hare is gamer most high in Vit B niacin that support energy metabolism.
Duck, source of iron and selenium, minerals that are immunity supporting.
Mussels are very eco friendly, taking relatively little energy. They also capture carbon dioxide and lock it up in the shells.
Laboratory grown artificial meat is tounted as a potential replacement, however it has its drawback of being too expensive to produce.
Insects are an option but perhaps unpalatable one.
