All these questions are common and reasonable. Many vegans held these beliefs at some point in time.
Nature does not require us to eat animals even though it did play an important role in our evolution. Humans are not obligate carnivores – unlike cats for example. From a physiological perspective, it is not necessary to eat animals and is therefore a choice – one that we can critically examine unlike our ancestors. Furthermore it is healthy and nutritionally complete to live on a vegan diet even during pregnancy, lactation, infancy, childhood, and adolescence, and for athletes.
Veganism is growing very fast in Australia and many popular celebrities are now vegan. Unlike a fad however, veganism is a positive philosophy of compassion for all sentient beings. It is a commitment to being our best until we know better… then being even better! Unlike difficult diets, veganism is an awareness of a global problem and a conviction to live according to a solution as best as possible.
Of course you could, you just need to know why it is important to you. Many people go vegan overnight, others transition, but all of it happens because people learn why it is important to ‘get there’. If you need support or help contact us! There are social groups to join and transitional support for people wanting to go vegan.
Unfortunately many vegetarians are unaware that they still contributes towards animal death.
Whether vegetarians eat meat or not, by purchasing eggs from modern factory farms they contribute to the demand for all male chicks to be killed shortly after hatching. This is because they don’t lay eggs or get used for meat.
Cows are impregnated to produce milk, then their calves are killed as young as 3 days old, or taken away from their distraught mothers and killed at about 6 months age for veal. Cows live up to 20 years age naturally, but all cows including dairy cows are deemed unproductive and killed for pet food at around 5 years age.
