Human activities are damaging our marine environment, and ocean pollution threatens human health, a piece of new research has uncovered. The research was conducted by an international research team that published their results in the journal Annals of Global Health. They wrote about the widespread damage to the oceans by the actions of humans, which in turn also cause damage to human health.The researchers also made several recommendations regarding solutions to lessen these damages.
The study detailed the latest scientific findings of the critical role that the oceans play in our health and the health of our planet. It also examined the key factors damaging ocean health. With the increase in temperatures worldwide, the melting of sea ice also increases. It causes an increase in harmful bacteria and algae (藻类) into waters that were unpolluted in the past.
Coastal populations are threatened by the rise in sea level and the increasing frequency and violence of coastal storms. The increase of carbon dioxide levels in the atmosphere increases ocean acidity (酸度), which destroys sensitive food chains in the ocean. Climate change also worsens ocean pollution.
According to the study’s author Philip Landrigan, who is also a professor and Boston College Global Observatory on Pollution & Health director, the pollution in the ocean is a major problem. It is getting worse and is directly affecting human health. Landrigan also adds that the ocean’s plastic pollution is not the entirety of the problem.
According to Landrigan, the toxic pollutants that are dumped into our oceans are finding their way into people’s bodies. The pathway is mainly through the consumption of polluted seafood. The most severely affected sectors include those fishing communities and small island countries. Their lives are dependent on the health of the ocean.
The research team suggests several measures to turn the situation around and save our oceans and our hea
