what has growing demand for food, fuel and other resources led to?
deforestation
afforestation
conversion of grasslands
oceans acidification is increasing due to fossil fuel combustion
ocean acidification is a huge problem as oceans are a huge carbonsink, increased acidity means more carbonic acid dissolves in calcium carbonate negativly affecting marine life and some creatures need it to make shells e.g. phytoplankton
coral reefs also rely on calciumcarbonate and a reduction will see them begin to dissolve and lead to permanent damage going past the critical threshold
humans have influenced climate change by adding to the greenhouse effect by burning more fossil fuels
this leads to more drought and death of trees releasing more carbon, a case study for this is the Amazon drought events:
severe drought between 2005 and 2010
plants and animals used to moist conditions died
photosynthesis slowed down = less carbon taken out atmosphere
