As sea exploration makes it possible to discover new sources of food and energy and improves our understanding of life on the earth，some are in favour of it.Opponents of sea exploration think that it may bring about so much pollution that it can destroy the underwater ecosystem.Besides，with so many marine animals murdered without mercy，the diversity of sea species is being destroyed. Personally，balancing environmental risks with economic needs can guarantee harmonious sea exploration. Yours， Li Hua $$
