参考范文：
In recent years, fishing resurces in the cean have been faced with a severe situatin with the quantity f fish and their species drpping sharply.
In my pinin, it is human behaviur that is t blame. Industrial and agricultural waste such as chemicals and il is pured int the cean. What's mre, verfishing destrys the balance f life in the cean.
T handle this situatin, laws shuld be made t punish thse wh vilate the law and cause pllutin. Besides, sme fishermen may take ther jbs s that there are less peple living n fishing. Only with these measures taken can we eventually preserve fishing resurces.
