I decided to became a vegetarian.
People become them for various reasons.
My number one reason is my health.
Another reason people have is out of respect for sentient life.
That is also an important part of becoming a vegetarian.
Indeed.  Political, Environmental, and Economic reasons also play a large roll in important reasons why people become vegetarian.
It is a great lifestyle to follow.
A vegan diet excludes all animal products as well.
