O que significa a expressão S.O.S ?


SOS: SAVE OUR SEAS!
It covers more than 70 percent of the Earth’s surface. It is an essential source of food and water. Millions of species of plants, animals and microbes live there. The sea and its treasures. Our precious beautiful sea. 
The sea regulates atmospheric gases, affects the planets weather, provides foods and jobs for humans, and is home to countless species – about 80 percent of the worlds biodiversity lives in the ocean
But the oceans are in trouble, because every day we do something to threaten them. Marine pollution is a serious problem these days.  Ships dump toxic waste, tankers leak and spill oil, river systems carry pollutants such as pesticides herbicides and other poisons to the ocean.
Every year, three to four million tons of oil pollute the sea.   
Is the situation hopeless? Can we overcome the threat to the ocean? In every corner of the planet, expects, United Nations agencies and other defenders of the environment are waving the red flag: Stop the damage! The ocean is not a garbage can!   

Caro leitor! Estude e boa sorte!
