The fact that a substance is necessary for life doesn't mean that too much of it can't harm you. Almost any necessary element will harm you if you get too much of it.
Another thing necessary for the continuation of life on earth is H2O, also known as water. And like CO2, too much of it will kill you.
And not only will CO2 kill you, it also traps heat in the lower atmosphere, thereby warming the planet.
