* What is happening? What is the change or event that you are referring to? For example, are we talking about:
* Pollution: What type of pollution (oil spill, plastic, agricultural runoff)?
* Climate change: Rising temperatures, ocean acidification, changes in salinity?
* Overfishing: Removal of certain species?
* Construction: Building a dam, dredging a channel, or creating a new habitat?
* Introduction of invasive species: A new plant or animal entering the ecosystem?
* Where is this happening? Is it a specific location (like a lake, river, or coral reef) or a broader region (like the Great Barrier Reef)?
* What aspects of the aquatic environment are you interested in? Do you want to know about:
* Plants: Algae, seaweed, mangroves, etc.
* Animals: Fish, shellfish, invertebrates, marine mammals, etc.
* Water quality: Temperature, salinity, oxygen levels, nutrients?
* Ecosystem function: Food webs, biodiversity, nutrient cycling?
Once I have this information, I can give you a more accurate and specific answer about how the aquatic environment will be affected.
