<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>

Explanation:
Personally, I didn’t know that it was being terraformed. I should start watching the news. Anyway, my opinion is that it’s probably just going to turn out like Earth. I feel like anything scientists can get their hands on, they will probably treat it like a lab rat. Hmm, maybe it’s that they’re terraforming it for the rich; and leaving the rest with catastrophic Earth (which is ruined), sadly, I don’t think anyone really cares about the planet anymore because everywhere there’s a problem. And why do we have to pay for food that was purposefully grown and brought out to the world for free? You can probably tell, I don’t like the idea of Mars being terraformed. Maybe they should just leave it as it is, or clean up the Earth before they mess up another planet unfortunately.
