Scientific monitoring is going to be terrifically important, because whatever steps we take ... we will have to monitor those steps in order to know if they're actually working.

We don't survive without plants and animals because we rely on them, we rely on plants to put oxygen into the atmosphere, we rely on ... fish and crops and cows to eat.

Scientists have been saying, for an awfully long time, that we're all interconnected. Scientists would use the word 'ecosystem' to express that idea. Obviously, people can't survive without air and water, and we rely on plants and animals for food, and plants and animals rely on us to preserve their habitats.
