FOOD

 

as i was buying chicken i saw on the back side saying preservatives used but it dint showed what kind of preservatives was being used.and then i began researching on food preservatives.

Food preservation is the process of treating and handling food to stop or slow down spoilage (loss of quality, edibility or longer value value) and thus allow for longer storage.

Preservation usually involves preventing the growth of bacterica, fungi , and other microorganism (although some methods work by introducing benign bacteria, or fungi to the food), as well as retarding the oxidation of fats which cause rancidity. Food preservation can also include processes which inhibit visual deterioration that can occur during food preparation; such as the enzymatic reaction in apples after they are cut.

Why should I be aware of this?

We are getting more and more distanced from the source of our food. Now food not only has to travel farther and farther but, for this very reason also needs to be stored longer. To keep this food from going bad new preservative methods have evolved without which bread would get mouldy, and salad oil would go rancid before it’s used up. Moulds growing on decaying food have caused many epidemics in many parts of the world.

after researching i came to know that they use a lot of ammonia to preserve meat. and the original chicken came from the mexico.

it was grown and rain in a factory farm. chicken were vaccinated there to control disease.

food preservation provide health benifits because it preserve nutrients. but the way a lot of chemicals are used in the food made me doubt if they really provide any health benifit. i dont thing eating ammonia is benificial for the body.

How does this affect me

Chemical preservatives are harmful because our body’s digestive system doesn’t know what to do with the stuff preservatives are made of and will either eliminate it or store it somewhere. And when it reacts in our body we suffer the consequences with illness.

Preservatives are subject of endless debate among academics and food science and toxicology specialists. It is argued that most products contain preservatives in minute dozes and, therefore, can’t kill.

it is grown is a big farm. it covers a lot of land. a lot of pesticides are sprayed in that area to prevent disease. which cause the grass or the land biodiversity disturbance. it will lead to a environmental degradation.

it was grown by small farmers in mexico and then they importo usa factory. and the major profit is made by the usa factory rather than mexico farmers.

 

 

 

 

all about environmeltal science

there are so many things we dont know thats why we dont do it. and there are many things we know thats why we do it. and there are much more things we know and we dont want to do it. from this class i came to know that we( all human beings and the activities) are the creator of the environmental hazard which is causing problems to us and the animals and the mother earth.

i thing  global warming is an important issue in this century. it is causing problem to many people and wildlife and the biodiversity. we know the causes and we know the solution too. so we all human beings should be togather to work on this problem so that we can make a change and save life of the eath and animals and we people.

alternative energy info

 

in Indiana states the alternative source of energy are wind farm, and the solar panel, which ware helping the people of the Indiana to pay less bills for their electricity. if you’re thinking all this alternative energy seems uncharacteristically progressive for a place like Indiana, you need to get with the times. Wind power has become a big business, and the wind doesn’t blow only in blue states.

Wind energy is one of the most cost-effective renewable energy resources, which is vastly and widely being adopted, especially on a mass scale to be a power generation source. By the mid of 2009, no less than 80 countries were using wind energy on a commercial level.

Unlike conventional fossil fuel power plants, windmills don’t emit any greenhouse gasses and even if they are removed they don’t leave any sort of pollution behind.

Off shore wind farms and those set up at higher altitudes which produce more energy can return the investment in as little as three months, which is why they are becoming more and more popular, especially at homes.

and i thing why there is no wind farms in chicago? this is a windy city so i thing government should take advantage of this natural gift of this city . but while i was researching this issue i found out that windfarms is coming in chicago too pretty soon(zack christmas, NBC chicago).
