20世纪末的法国马赛,由于工厂将污水直接倒入海中,导致水生植物没法透过暗污的海水晒到太阳,最终连同以它们为“家”的水生动物一起消失了。为此,人们建起污水处理厂,使海水恢复了清澈,但水生生物“重归故土”的生长速度却慢极了。为了建“新房”吸引水生生物前来入住,一些创意无限的环保科学家,居然玩起了废物利用,将报废的飞机、汽车、钻井平台甚至航空母舰,投入海底,造出了千奇百怪的人工鱼礁!航空母舰、战斗机、坦克鱼礁出于有钱、任性,一些国家居然用退役航母、报废的坦克或者战斗机来做鱼礁!这些装备往往很重,一旦沉入海底,便稳如磐石。当海流 Marseilles, France, at the end of the twentieth century, because the factory dumped the sewage directly into the sea, causing the aquatic plants not to bask in the sun by the dark soils, eventually disappearing together with the aquatic animals that they made their “home.” To this end, people built a sewage treatment plant, so that the water was restored to the clear, but the aquatic life, “return to homeland,” the growth rate is extremely slow. In order to build “new house” to attract aquatic creatures come to stay, some creative environmental scientists, actually playing the waste utilization, the scrapped aircraft, cars, drilling platforms and even aircraft carriers, into the sea, creating a strange artificial fish Reef aircraft carriers, fighters, tank reef out of money, self-willed, some countries actually used retired aircraft carrier, scrapped tanks or fighter to do reef! These are often heavy equipment, once submerged, rock solid. When the current
