Preservation of seaweed beds is seen as an important issue. However, the seaweed withering phenomenon is also a major problem that deserves attention. As the reduction of the seaweed beds continues it has been found that grazing by sea urchins and herbivorous fishes are the principal causes..To remove sea urchins directly by fishermen and divers is effective but is a burden for fishermen. Thus, from an environmental protection perspective, there is a need for public assistance. In order to decrease the population of herbivorous fishes, their consumption should be actively promoted.After such countermeasures are taken, monitoring must definitely be conducted and the quality of the countermeasures evaluated. Flexible management should be adopted, allowing other approaches if the results of the evaluation prove the countermeasures inadequate.

One of the guiding principles of understanding the processes and impacts of climate change is concerned with looking back in time to see how climates and ecosystems have changed, or put another way, the past is the key to the present, which in turn is the key to the future. By understanding the past we can wholly understand the present, we can then project this understanding towards future 'what if ?' scenarios.The Eastern Arc Mountains are well known for their great floral and faunal diversity, and why it may be able to retain such biological wealth under past climate change is finally going to be tested by a new research.

Off the coast of Ikitsuki Island, Nagasaki Prefecture, there is an artificial upwelling structure designed as a pilot project of the Fisheries Agency, where results such as the formation of a new fishing ground for sardines and the making of an offshore fishing ground are forthcoming.In addition to these merits, it should contribute to the reduction of CO2 in the atmosphere, because marine snow which yields CO2 accumulates for ages in the sea and its deep layers.
