The COVID-19 pandemic requires a response to remain healthy. Strict measures like quarantine aim to curb spread, but approaches like frequent nucleic acid testing of asymptomatic individuals may backfire by causing infections and quarantining of non-infectious people. Once recovered and asymptomatic, are people still infectious? Mathematical reasoning shows asymptomatic, recovered individuals are non-infectious. They cannot infect themselves or show symptoms, so a "healthy carrier" is impossible. This applies to Mary Mallon, the first "healthy carrier", correctly attributed to hygiene, not Mallon herself. Asymptomatic,recovered individuals are non-infectious. Recovered from infection and asymptomatic, they would be even less infectious, like vaccination.Nucleic acid testing of asymptomatic individuals is unnecessary, cannot confirm infectivity, and may infect. Infectivity should be determined by health and symptoms, not testing.

The North Sea has been studied for oceanography for 150 years. Interest has focused on artificial ocean alkalinization to mitigate climate change,which may impact environments by disrupting alkalinityintegral to biogeochemistry.

The BlueHealth project examines blue space impacts; aims understand health relationships, quantify impacts, and inform policymakers. It creates evidence through reviews, data analysis, surveys, and interventions.
