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.
