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.

ON THIS PICTURE, YOU CAN SEE IN DARK GREEN THE SPECIES WHICH HAVE ALREADY BEEN DISCOVERED. THIS IS COMPARED TO THE SPECIES WHICH YET HAVE TO BE DISCOVERED THAT ARE SHOWN IN LIGHT GREEN. ON THE RIGHT SIDE, YOU CAN ALSO SEE THE SPECIFIC DATA FROM WHICH THE CHART IS MADE.

This picture is a global reprensentation on what is biodiversity.
