Life - from Politics to Philosophy Plato was born in Athens in c. Until his mid-twenties, Athens was involved in a long and disastrous military conflict with Sparta, known as the Peloponnesian War. But this never happened. Although cherishing the hope of assuming a significant place in his political community, he found himself continually thwarted.
More fishy Table Talk Posts The Tuna Pickle Sushi and canned tuna fans are plentiful, but our insatiable appetite for tuna has driven many of the tuna species to the brink of extinction. Why does tuna matter? Besides being delicious and wanting to preserve tuna stocks for generations to come, Tuna, like Sharks, are apex predators — top of the food chain with not many natural predators.
Taking too many apex predators out of our oceans disrupts the entire ecosystem. Tuna are slow-growing and long-lived fish, meaning they take a long time to get to an age of sexual maturity in order to reproduce. This means populations in decline take a long time to recover.
Also, current practices of taking juvenile Bluefin Tuna out of the oceans and placing them into sea-cage farms to be fattened means they are killed before they are able to produce young.
With it taking up 10kg of feed to produce 1kg of tuna, is tuna farming something we should be practising? Are the health concerns around eating tuna valid? The health concerns are around mercury levels, because mercury can affect brain and nervous system function and development, particularly in developing foetuses.
Mercury is found in the ocean and is consumed by all fish. Mercury gets more and more concentrated the higher up the food chain you go, so large predatory fish like tuna and shark right at the top of the food chain can contain harmful levels of mercury. What about canned tuna?
Labelling Woes If you consider yourself to be an ethical meat eater then chances are you know exactly where and how to select meat so that the origin and farming methods are known. When it comes to being a mindful seafood eater, it is not so easy.
To make an informed choice, we need to know: The standardised name of the fish or species The fishing technique used or method of aquaculture The country of origin or even more specific details such as the catch area Expand In Australia, country of origin labelling is now legally required for seafood products.
This is a step in the right direction for seafood traceability, however it applies only to retailers — restaurants are not required to inform customers where their seafood comes from.
The best you can do is ask questions and express your desire for more information and clearer labelling on menus. Also look out for the blue MSC eco-label when shopping or dining out. The Marine Stewardship Council MSC is an independent, non-profit organisation that provides certifications and eco-labelling for sustainable wild-captured seafood.
Label My Fish Campaign You can have your say and push for better labelling laws in Australia by sending an email to the government via the Label My Fish website.
Every email sent is a step closer to better labelling standards across the country. Usually they are thrown back into the ocean and are often dying or are already dead.
The fishing methods used to catch Tuna, Blue Grenadier or Hoki and wild-caught Prawns yield some of the highest levels of bycatch. Fished to the max — overfished species Overfishing occurs when more fish are caught than the population can replace through natural reproduction.
Overfishing has placed many fish species near extinction. Fishing methods a Fisheries use a range of different techniques to catch seafood. Some of these have a much greater impact on marine environments than others, so it makes sense to support those fisheries that employ least-damaging fishing techniques.
Some lower-impact fishing methods include pole and line fishing, dive collection and pots and traps. Fishing methods that are known to have a negative impact include bottom trawling, gillnet and dredging, which is often used to collect scallops and clams.

There are also issues of fish welfare, pollution, land degradation and impacts to native fish populations and eco-systems. Carnivorous fish raised in farms are fed wild caught fish in the form of fishmeal pellets comprising small schooling fish species.Introduction In evaluating ethical systems we can be lost in a maze of systems, details, and terminology.
Such arguments lead nowhere, shed little light on the subject, and polarize people into opposing camps.
Aug 09, · Platforms, Speech And Truth: Policy, Policing And Impossible Choices from the deplatforming-and-denialism dept. A guide on how to use the APS Values and Code to make ethical decisions in the APS. The timeworn and pedestrian answer is simply "to get to the other side." Here are some creative and original answers: The chicken crossed the road.
What Makes a Species ‘More’ or ‘Less’ Sustainable? ‘Sustainability’ is a very hard thing to define, especially when it relates to seafood. It will be instructive to examine each of these four ethical systems and then consider the role that each might play in a comprehensive ethical theory.
These particular ethical systems have been selected because, in addition to achieving noteworthy status in the philosophy of ethics, each reflects a .
