Explanation:
The effects are felt much greater for older adults who have lost a spouse due to it being compounded on the grief that the older adult is feeling from the loss of their spouse.

One organism that was influenced is fish in the ocean thanks to the Plankton. Because of the increasing amount of CO2, the plankton which lives off of it has started to multiply and take away more and more air from the water which is causing fish to die out. Thanks to this, huge amounts of water are full of dead fish and are polluted almost beyond repair. This is also seen in the coral reef area which has started to die out.
Another one affected on land is the polar bear which has more and more difficulty finding food and have even been reports that they've turned even to eating eggs of other animals because the way the CO2 is affecting the freezing of the sea they have problems finding food.
