Title: The Impact of CO2 Emissions on ‘Nuisance’ Marine Species
Introduction
CO2 emissions a have a significant effect on marine life (Hall-Spencer & Allen, 2015).
The decline in PH due to the rise in CO2 levels in the sea endangers certain sea organisms while it favors others (Doney, 2006).
The problem has necessitated the need to investigate the effect of ocean acidification on the marine taxa and especially ‘nuisance’ marine species.
The study will assess the responses of dangerous aquatic species to ocean acidification.

Body
Experiment
The study evaluated possible responses of aquatic species that have undesirable effects to humans on ocean acidification.
It was performed by analyzing current evidence on the issue.
Experimental Results
After synthesizing recent evidence, it was anticipated that increased levels of CO2 in seawater are likely to proliferate the growth and toxicity of harmful marine species such as the alga bloom and the invasive algae (Hall-Spencer & Allen, 2015).
According to the results, it is also expected that the blooms of sting jellyfish will significantly rise since they can withstand acidic conditions (Hall-Spencer & Allen, 2015).
However, marine species such as invasive molluscs and aging echinoderms are expected to respond to ocean acidification depending on their taxa and location.
Conclusions
The researchers conclude that there may be a possible rise in nuisance species as most of them are resistant to ocean acidification arising from the increased levels of CO2.

This is because acidic conditions are favorable to some species that are regarded as harmful by human beings.
Future research questions
What is the effect of declined PH on nuisance species in their local habitat?
What is the impact of global change on dangerous sea organisms such as starfish, seaweed and, lionfish and invasive ascidians?
Future experiments
Effect of carbon dioxide emissions on non-invasive aquatic species.
Transition into conclusion
Conclusion
In conclusion, possible ocean acidification due to the rising levels of CO2 in seawater leads to a rise in harmful aquatic organisms such as alga bloom and the invasive algae.
It is evident that ocean acidification favors nuisance marine species.
Therefore, this calls for the need to minimize CO2 emissions, as they are increasing the spread of dangerous marine organisms.
