From How Many Marine Mammals Did Your Plastic Grocery Bag Kill Today? posted by: Jennifer Mueller Care2

With DisneyNature opening a new film about the ocean on Earth Day, scientists confirming an Atlantic garbage patch that rivals the one in the pacific, I think we are going to be hearing a lot more about plastics in our oceans. The attention will be well deserved but I struggle with is what to do next. Surfrider and others suggest we all reduce our plastic use and therefore plastic trash. Great. But, is that going to do it?

The city of San Francisco and the entire country of China banned plastic bags entirely. What do YOU think we should do about PLASTIC in the OCEAN?

Ingestion of avocado - Persea americana
has been associated with:
--Myocardial Necrosis mammals and birds and
--Sterile Mastitis lactating mammals.
.Dogs, cattle, goats, horses, mice, rabbits, guinea pigs, rats, sheep, budgerigars, canaries, cockatiels, ostriches, chickens, turkeys, and fish are susceptible.
.Caged birds appear more sensitive to the effects of avocado, while chickens and turkeys appear more resistant.
The poisonous ingredient in avocado is persin.
Ingestion of fruit, leaves, stems, and seeds of avocado has been associated with toxicosis in animals;
- leaves are the most toxic part.
The Guatemalan varieties of avocado
have been most commonly associated with toxicosis.
.Goats develop severe mastitis when ingesting 20 g of leaves/kg, whereas 30 g of leaves/kg results in cardiac injury.
.Sheep: acute cardiac failure developed in sheep fed avocado leaves at 25 g/kg for 5 days; 5.5 g/kg of leaves fed for 21 days or 2.5 g/kg for 32 days caused chronic cardiac insufficiency.
.Budgerigars fed 1 g of avocado fruit developed agitation and feather pulling, while 8.7 g of mashed avocado fruit resulted in death within 48 hr.
Diagnosis of avocado toxicosis relies on history of exposure and clinical signs. There are no readily available specific tests that will confirm diagnosis.
Clinical Findings: In lactating animals, mastitis occurs within 24 hr of exposure to avocado, accompanied by a 75% decrease in milk production. Affected mammary glands are firm, swollen, and produce watery, curdled milk. Lactation may provide a degree of protection against myocardial injury at lower doses.
In nonlactating mammals, or at higher doses, myocardial insufficiency may develop within 24-48 hr of ingestion and is characterized by lethargy, respiratory distress, subcutaneous edema, cyanosis, cough, exercise intolerance, and death.
may develop edema of the head, tongue, and brisket.
.Birds develop lethargy, dyspnea, anorexia, subcutaneous edema of neck and pectoral regions, and death.
