upon healthy oceans and seas. Much of
the oxygen we breathe is generated by marine
life, while ocean currents transfer heat, playing
an important role in maintaining a moderate
climate.
However, the marine ecosystems that keep the
oceans healthy are subject to increasing stress.
Many of the stress factors are either caused, or
worsened, by human activities on land. As we
burn more fossil fuels, more carbon dioxide is
emitted, trapping heat that warms the oceans.
Ocean waters absorb about a quarter of that
carbon dioxide, which dissolves and increases
ocean water acidity
