Hello Gangt181, The current increase of carbon dioxide in the atmosphere is as a result
of human activities that began in the late 1700s. This period sparked
the beginning of the Industrial Revolution and this is when we began to
use fossil fuels. The burning of fossil fuels coupled with widespread
global deforestation has led to a rise in CO2. Excess carbon dioxide in
the oceans causes it to become more acidic. This acidity will affect
marine species with shells like mussels and lobsters.
