You can't live without it. Here are two examples:
Plants absorb carbon dioxide and emit ogygen. You can't live breathing carbon dioxide.
Most of the fruits we eat are dependent on insects (mainly bees) to pollinate the flowers so the fruits will form. If every bee's ecosystem was destroyed and bees disappeared, we wouldn't have any fruit and very many plants would simply disappear.
Our ecosystem is many things and not just plowed land for growing corn.
