The problems of the oceans As we know, the ocean covers 2/3 of the planet's surface and delivers up to 1/6 of animal protein, are eaten by the inhabitants of the Earth. About 70% of all oxygen is produced during photosynthesis of phytoplankton. Chemical pollution of the ocean is extremely dangerous, because it leads to the depletion of water, food resources, the disruption of the oxygen balance in the atmosphere. During the twentieth century greatly increased emissions in the world's oceans posable synthetic substances, products of chemical and military industry.Проблемы мирового океана Как известно, мировой океан занимает 2/3 поверхности планеты и поставляет до 1/6 белков животного происхождения, которые употребляют в пищу жители Земли. Около 70% всего кислорода вырабатывается во время фотосинтеза фитопланктона. Химическое загрязнение океана крайне опасно, потому как ведет за собой оскудение водных, пищевых ресурсов, нарушение кислородного баланса в атмосфере. В течение ХХ века сильно увеличились выбросы в мировой океан неразложимых синтетических веществ, продуктов химической и военной промышленности.
