Any Vegetarians/Vegans here?

4) The land needed to cultivate soia and other feed for animals also come at the expenses of less forests..

Soys and other feed for the animals undertake the same processes to give clean air as trees in forests.

6) The smell of meat cooking make veg. people sick..

Good, perhaps you would die.

What a load of nonsense. Soys and other feed do undergo photosynthesis and capture CO2, but unlike trees they are harvested/ transported etc. and that creates a lot of CO2 emissions. Additionally CO2 captured by trees is then stored as wood, whereas with grains it is released back into the environment when digested by an animal both as CO2, and more importantly as methane, which is 20 times more potent green house gas than CO2. All farming therefore puts CO2 into the air and according to the FAO agriculture contributes 18% globally to our CO2 emissions, and potentially considerably more in developed countries. The emissions from eating grains directly are therefore considerably less than feeding them to animals and eating meat.

Additionally, what is wrong with you? Wishing another person to die just because they disagree with you in debate on the internet?

Adding plants to a diet is merely supplementing a meat based diet with plants, therefore plants could be considered a "supplement"

EXACTLY. Its moronic to think supplementation is wrong, or to single them out as somehow apart from the rest of ones diet. Plants indeed could be considered a supplement to a meat diet, if you consider meat to be the starting point of a "natural" diet. My point is that for humans there is no such thing as a natural diet. Vitamins supplements are for vegans just another part of our diets that are required for obtaining certain vitamins. For omnivores that don't take supplements, eating meat is just a part of the diet that contains certain vitamins. Your argument that a diet that requires vitamin supplements is not healthy makes as much sense as me arguing that a meat diet that requires plants is not healthy. You are not arguing for a meat diet that excludes plants, and I am not arguing for a plant based diet that excludes vitamin supplements. All these foods just have different ethical, environmental and health impacts. For the latter this is determined by EVIDENCE, not just because certain parts of a diet are labelled as a supplement. And all the evidence shows that vegans are healthier.
