Understanding the climate of the past, and knowing what we know about climate changes today, it does give us an idea that this type of an ecosystem is a hotbed of diversity, and they are highly susceptible to changes, whether due to the climate, the chemistry of water or carbon dioxide in the air, Holliday said. Fanboyphilosopher(Neil Pezzoni)/Wikimedia Commons/CC BY-SA 4.0.
