When it comes to farming fish most people think this is the way of the future. That fish farming will help solve the problem of over fishing. Since over fishing in the ocean began, various fish stocks have collapse. This has left whole fishing towns with nothing. However, in some cases farming fish can have just as severe effects.
One of the most popular fish stocks to farm is the Atlantic salmon. Atlantic salmon is higher on the food chain compared to other fishing stocks like Tilapia. Atlantic salmons diet mainly consists of other fish. Tilapia and catfish, on the other hand, are mostly vegetarians. We get the fish to feed these farms full of salmon from the ocean. Fish like anchovies and sardines are caught by the millions and made into fishmeal. So the oceans are still being over fished. The fishmeal is then sent to various fisheries to support the growing number of fish farms in America. When it comes to feeding the salmon it takes approximately three pounds of wild fish to produce one pound of salmon, as stated by edf.org.
There is also the problem of pollution for most of these fish farms. These fish farms consist of many fish jam packed into a small area. As the fish grow there feces builds up quickly, and there is nowhere to put such a quantity of excrement. In the wild, the current will break down the poop quickly, and no build up will occur. Another problem for fish farms is the mercury content of this fish is more concentrated. This is mainly due to them only being fed fish. Wild salmon populations do eat fish; they also maintain a diet of many other organisms.
Where fish farming is making strides is in the catfish and Tilapia market. However, they still have problems with pollution it is not as severe. Monsterfishkeepers.com states that it only takes 1.2 pounds of food to produce 1 pound of Tilapia. Tilapia is lower on the food chain, so they do not need fishmeal as much as salmon do. However, more fishmeal is starting to be added to the diets of Tilapia to gain weight faster. The same thing is currently occurring with catfish.

Very many years ago, when the world was green and the environment was pollution free, livestock and poultry were fed foods that were unadulterated or polluted by pesticides or hormones. Advancement in science and technology and the material needs of the human being has pushed him to devise new methods to increase his production, be it food grains or livestock. So eating meat today is totally different to eating it long ago, as today’s meat is adulterated and contaminated meat, which is very harmful to us.
The farming techniques in vogue today increase production but the environmental damage they cause has to be borne by the future generations of our planet. In the United States, which is a huge consumer of animal food, raising livestock is a huge burden on the environment as the food and water to raise animals requires more than half the available resources in the United States.
This livestock farming industry also contributes to pollution in a big way by polluting our rivers and lakes but also cause soil erosion, which can turn disastrous in the future.
Almost ninety percent of the entire farmable land of the country is used for livestock farming. That is almost half of the land mass of the United States.
Other factors that cause heavy environmental degradation is methane emission, the chief contributor to methane emission is cattle.
Livestock farming or raising animals for food has caused irreparable damage to the country’s water resources as the huge volumes of animal excrement end up in our rivers or lakes.
The available raw materials and fossil fuels in the United States is consumed by this animal farming industry and this industry alone consumes a whopping 33 percent of available fossil fuel resources.
Forests are destroyed to make space for animal farming. The moral aspect of this involves cruel treatment of the animals themselves, add to this the overhead costs involved in animal farming then eating animal meat is like an inhuman way of killing our economy and our planet itself. So make a pledge today to say no to animal meat in your food and turn to alternative healthier way of living like vegetarian diets. Make the decision that will change the planet for good and make a … Read More
