DAY 3 HOMECOMING

Currently, I study I am currently studying in Cádiz, but live in I am actually from Cordoba. Today, I come am coming home to Córdoba for the weekend. I'm looking forward to see my family and my dogs.

Note: The way you said things can be understood but I just corrected and rephrased some phrases in order for it to sound more natural.

Have you ever tasted "Dulce de Leche"?

What is "Dulce de Leche"? Well, it's a jam made of milk (cow's milk), which is originally from South America. I think that "Dulce de Leche" is older than South America itself. There are many stories about how it originated, but the truth is that "Dulce de Leche" is one of the most South American products and it's a piece of our history and culture.
It's not really difficult to cook. You just have to boil milk with sugar to get it and in a while, you will enjoy one of our best products as a continent.
I know that there are two kinds of Dulce de Leche but I am sure there are more, one is the "Colonial Flavor" and the second one is the "Traditional/Classic Flavor" I prefer the colonial flavor.
Dulce de leche is also used to make another traditional candy from this land that is called "alfajor" it's like a cake but in a very small size that could fit in the palm of your hand.

So what are you waiting for? Taste Dulce de Leche by preparing it yourself!

Note: Regarding the last part, I just guessed what you are trying to say based on your choice of words. I decided to rephrase it ad I hope my assumptions are right. :)

ENVIRONMENTAL PROBLEMS

I'm going ti   to write about the next topic:

"Your Town Hall has recently decided to build a factory near an important nature
reserve. Write a letter to the mayor to protest against the building of the factory.
Include ideas about the importance of environmental balance, health problems, and a
proposal for a better location of the factory."

Dear Mayor,

I am very severely disagree with the building of the factory near an the nature reserve because there are a lot of different kinds of biodiversity in it and, it is also near the village.

If you will build the factory, there will be more pollution and noise. Consequently, there will be animals which that will died and others will go out*** be dispersed. Moreover, there will be acid rain having that will have an effect to on the plants, the animals and the population. In addition to that, people will have health problems.

Nowadays, the Global Warming is s truth, a reality. so If people could do one's bit**** part, the Global Warming wouldn't exist worsen or continue. We are using up the Earth's natural resources faster than ever.

It is for this these reasons that I think the building of the factory have ought to be farther far from the village and the nature reserve.

I am looking forward to hearing from you.

Yours sincerely,

Patry.

***What do you mean by "will go out"? Does it mean they will move out of their habitat or the animals will die out?

****'bit' is too informal for this kind of letter so I changed to word to 'part' for it to be a lot more formal

You did great, Patry. You just need to work on you choice of words as well as knowing when to put a comma, when to capitalize a word and when to put a stop to a sentence. Nevertheless, it was a nice piece. Keep up the good work! :)
