deforestation
One cost of the terrestrial losses is the deforestation.
One cost of the terrestrial losses is the deforestation.
Now I’m going to speack about terrestrial ecosystem loss. This picture is about deforestation, the net loss of forest is mainly in the south of America. However the net gain of forest is located mainly in America AND EUROPE
THE FOLLOWING MAP SHOWS HOW MARINE DEAD ZONES ARE GLOBALLY DISTRIBUTED. MOREOVER, THE BAR CHART SHOWS THE DRAMATICALLY INCREASING NUMBER OF DEAD ZONES FROM THE BEGINNING OF THE PAST CENTURY TO THE PRESENT DAYS.
AS YOU CAN SEE, THE LARGEST AMOUNT OF DEAD ZONES IS CONCENTRATED AROUND INDUSTRIAL AND RICH COUNTRIES SUCH AS THE USA, EUROPE AND JAPAN WHERE POLLUTION LEVELS ARE VERY HIGH AND FISHING IS BROUGHT TO AN EXCESSIVE EXTENT.

This is an effect on species loss. But you have also the pollution that you can show on this photos.
About marine, i ‘m going to speak about fishing . The fishing increase since 1960 and currently we have 10 million tons fishing.

On this picture you can see the marine ecosystem loss with on the left the key ecosystem services and on the right the major loss mechanisms. On the right you have dredging and boating effects. Coastal salinity chenges beacause of altered water flow for irrigation. THE POLLUTION DISCHARGED INTO THE SEA BY DIVERSE HUMAN ACTIVITIES CAUSES EUTROPHICATION WHICH REDUCES THE LIGHT AND THE OXYGEN IN THE WATER. ALL THOSE ASPECTS PLAY AN IMPORTANT AND CRITICAL ROLE IN DAMAGING MARINE ECOSYSTEMS.

This picture shows the pErcentage of habitat lost and species threatened. The biggest pErcentage of habitat lost is in Europe and US. And the biggest pourcentage of species threatened is in Africa and India.
