  • All right, you could say I take a high moral ground while asking this question, but there it is.

    I am a strict vegetarian by choice, and my preference is guided primarily by ethics ("killing animals when they don't harm us is wrong"). But I am here not to discuss the ethics of vegetarianism (which I will be glad to discuss on My Desk), but the sustainability of being vegetarian.

    Apart from the obvious greenhouse gases increase owing to the large number of cattle population because of non-vegetarianism, there could be other aspects that hinder a progress to sustainable world.

    So, being vegetarian is not only ethical but also makes the world more sustainable. So, why isn't the world not turning vegetarian? Is it because they cannot control their taste buds? That sounds like such a crime!

    What are your thoughts?

      There is nothing wrong with killing animals to feed ourselves, because this is what they are created for. Our bodies need vegetables as well as meats.

    • Gaya3 1 year ago

      Generally the order of metal toxicity which affects the algal species is Hg> Cu>Cd>Ag>Pb>Zn. Mercury being the most toxic metal affects the enzyme systems of the algae and inhibits their functions. Copper is used to control the algal blooms in fresh water. The extent of toxicity depends on the ionic content or free Cu2+ ions available in the algal culture and not the total copper concentration.
