Pollution
=========

Write the function :py:func:`carbon_dioxide` that takes an amount of
liters of oil to make gas, and returns the number of kg of |CO2| (carbon
dioxide) that will be produced with this amount of oil, knowing the
following conversions:

- 1 barrel of oil contains 158.987 liters of oil
- with a barrel of oil, 74 liters of gas can be produced
- 2.3 kg |CO2| are generated for each liter of gas

.. |CO2| replace:: CO\ :sub:`2`

Save this function into a file named ``pollution.py``.

See the following examples:

.. literalinclude:: pollution.txt
   :language: python3
   :lines: 3-11
