Say you get bitten by a venomous snake you can have snake milkers take the venom from the same or another snake and they can make an anti venom to save your life. Now you may think all the uses for snakes are good, but allot of them are fatal to the snake. Now some people think that once a snake is milked it loses it venom forever. This is not true when a snakes old venom is taken out the snake just makes new venom. Even though the milking presses is not fatal to the snake lots of other things are.
Some people kill snakes just for their skins or too eat.
Some people kill baby snakes and stuff them in jars too sell too tourists. They even take live baby pythons and other snakes and sell them too people who don't care about them. They even take different parts of snakes for spiritual practices. Snakes should not be used for such harmful things. Not all uses for snakes are bad and this is only my opinion.
