【答案】Dear fellows，
With the approaching of World Ocean Day，we would like to call on everyone to protect marine animals.
Each year，millions of marine animals die from hunting and environmental pollution.Therefore，effective measures should be adopted before things get worse.Firstly，it is necessary to avoid purchasing products made from any endangered marine animals.Besides，please don't throw rubbish into the ocean，which will pollute marine animals' living conditions.
It is time that we joined our hands to preserve marine animals and create a harmonious home for them.
