Industrial Agriculture vs. Sustainable Agriculture

Have you ever sat down at diner and tried to figure out how a piece of cow “magically” became a piece of steak on your plate? We've all seen farm animals, whether it was when we passed by a farm or saw them on TV, but how does this food production thing work? There are two different answers to this : Sustainable Agriculture and Industrial Agriculture.


What is Sustainable Agriculture?

Sustainable Agriculture is a way of raising food fairly. It conserves and preserves, improves or sustains biodiversity, keeps animals safe, and keeps workers paid and treated fairly.One of the strongest characteristic of Sustainable Agriculture is its conservation and preservation side. When conserving and preserving, whatever is taken out of the environment is brought back. This makes resources like water and soil become replenishable and available for the future. Also, animals that are raised under Sustainable Agriculture are treated humanely and allowed to live freely and naturally. Another important characteristic of Sustainable Agriculture is its biodiversity. Farms that produce food in support of Sustainable Agriculture have a large variety of plants and animals spread across to keep soil rich, and to go with this positive factor pesticides are use very minimally . Personally I think that if the world became more optimistic to Sustainable Agriculture more people would find it more reasonable than the opposing system “Industrial” Agriculture. Although it’s more costly and inefficient it would put us and our environment in a lower risk.


Industrial Agriculture
Industrial Agriculture (AKA Factory Farming) is a said to be a more cheaper and efficient way to meet the worlds demands for food, than the opposing: Organic Farming(Sustainable Agriculture). This method uses the least amount of resources to generate the most profit, but this all happens at the expense of our environment and causes mistreatment to animals.Industrial agriculture also has a higher risk of disease spread and uses much more pesticides than Organic Farming. In this process our world becomes less bio diverse in exchange for money and profit.





Conclusion
If the world becomes less bio diverse species will begin to disappear, when this happens several other species that rely on that species will follow and be disappear too. Yes, we are told that Industrial Agriculture is fair and yes it is cheaper, but is it worth the cost of our environment? I think not. We must be more optimistic to alternatives such as Sustainable Agriculture even if it's a more costly and difficult process.

Designer Babies

What is a designer baby?



With the help of modern technology, doctors can now inspect embryos for diseases and illnesses. These embryos are later injected into a future mother to produce a healthy baby. Besides health concerns parents can now modify these embryos to eliminate unwanted genes and predetermine gender accurately along with several other attributes such as: height, blood type eye colour and hair colour.

How is this possible?

A procedure called IVF (In Vitro Fertilization) is used. In this process a woman is given fertility drugs in order to develop more eggs in her ovaries. A few hours later a needle is inserted into the woman’s ovaries to draw out fluid that contains her eggs. The eggs retrieved from the woman’s ovary are then mixed with sperm donated by the male partner and left in an incubator for 24 hours. During these 24 hours one of many sperm cells will penetrate the shell of the egg and begin fertilization, the cells will then divide and multiply becoming an embryo. These embryos are then inspected and selected according to the preferences of the parents. After a few days the selected embryo consisting of 8 cells will be transferred back into the uterus to form a pregnancy.

Is it right?

As a catholic the thought of designing my own child seems very unethical, the selection of several different attributes is unnecessary, it's sort of like we're playing God. But there's also a bright side to this practice, which is having the power to inspect an embryo for inherited illnesses and disease but even with that, this can expose our children to new unexpected illnesses.


All in all, some family's can find this very beneficial, especially family's with history of illness and disease but besides that we shouldn't turn “real life” into a game of Sims.

Something's Fishy...

Some people have large appetites, some people have eyes bigger than their stomachs, but when fish is brought onto the table our stomachs are larger than the ocean,this may sound silly but it's true! Our oceans can't handle the world's demand for fish, 1 of 5 people around the world are dependant on fish for protein, plus the millions around the world who use fishing as a source of income.

With fishing industries getting access to fish stock granted more than denied, it's extremely hard to prevent overfishing. Large fishing fleets take over the modern fishing industry and technology is improving rapidly giving these fleets incredible size and power.These ships are now able to locate schools of fish accurately, sometimes fishing out non targeted species and younger fish.



It's bad enough that the process of fishing is already faster than fish can reproduce but how can reproduction occur when the whole species is being wiped out (even babies)? These destructive fishing techniques have forced more than 70 percent of the worlds fishing stock to be either depleted or fully exploited.

Depletion and exploitation of targeted fish is not the only threat to marine biodiversity, we are also fishing down the food web.Fishing down the food web has many consequences, when we kill fish, we change the way organisms interact; dragging nets destroys habitats and a lot of bycatch is picked up, affecting marine biodiversity greatly.The loss of predators and larger fish changes biological interaction forcing larger fish to interact with smaller fish, this creates smaller species of fish. The food web then changes, making the ecosystems that once supported these organisms incapable of doing so, forcing them to either adapt or di

.

Life that was once present in these oceans have disappeared; abundant species are becoming scarce; predators are gone; even non targeted species fall victim. Although the world is on the verge of sucking the life out of the oceans, there is still hope! Strangely, we can reimburse our oceans. More so than land, the ocean can reset. If given time all the ocean's animals would return, all the organisms that have become smaller will grow back, all the relationships between organisms would rebuild, ecosystems would support all it's organisms again, but most importantly marine biodiversity would go back to how it was some 50 years ago... IT'S NOT TOO LATE!
