The current methods of how we get our food are raising cattle,
fishing or fish farming, and slaughtering. These all have positive
and negative effects on the environment. The positive effects of
raising cattle are that the cows give us the milk and meat we need
to eat/drink in order to get the proper nutrients. The
negative impacts are that some farmers give hormones to their
cattle so they can produce more meat which gives the farmers a
better profit. Although, the hormones given to the cows are bad for
us and can make us sick. The positive effects of fishing are that
fish provide significant nutrition and health benefits for
consumers worldwide. Fish Farming is a profitable industry and many
nations use it as a major source of income. Seafood makes a great
export for many countries and fish farming provides job
opportunities for citizens. The negative impacts are
that people are over fishing and this has
led to the breakdown of some sea ecosystems. Uneaten
fish feed, excrement and chemicals used for disease and parasite
control can flow from a fish farm's pens into the surrounding
water.There is the spread of disease and parasites and a prey fish
population depletion. Slaughtering of animals, the last major
method we use to get our food. There is a pollution control during
the slaughter, preparation, and processing of the carcasses. For
human consumption, vets examine before and after slaughter to
ensure the safety of slaughtered animals. Not anybody can slaughter
animals, butchers are legally qualified and liscensed for the
profession. There is a proper dealig of the slaughter remains.
These are all positive impacts of slaughtering animals. The
negative impacts are that there is an impact of health implications
of the community and families in the absense of a veterinary
inspection. Another negative impact is that
the spoilage of carcasses
not in cool areas and presence of high temperature in the slaughter
site are exposured to pollutants such as dust and car exhaust
smoke.
