Water pollution

Pollution in the world is a global problem that is affecting us today. There are campaigns to raise awareness of what is happening to the world and because of that i wanted to talk about this problem.

Water pollution, water incorporation of foreign matter such as microorganisms, chemicals, industrial waste and other types, or sewage. These substances impair water quality and make it useless for the intended uses.

The pollution problem arises now more sharply than in the past, for much of the waste have inorganic origin and are not attacked by bacteria disintegrating.

The effort to find a solution is hampered by population growth and the rapid industrial development.

Water pollution remains a problem as population growth continue to increase pressure on the environment. The infiltration of toxic waste in underground aquifers and saltwater intrusion in coastal aquifers of fresh water has not been interrupted.

The depletion of aquifers in many parts of the world and the growing demand for water will produce conflicts between the agricultural, industrial and domestic use of it. The shortage will impose restrictions on water use and increase the cost of consumption. Water could become the energy crisis of the early twenty-first century. Contamination of fresh and coastal waters, along with overfishing, has eroded to the point the fish fisheries resources would be necessary to close the fishery for a period of five to ten years for species to recover


Water pollution has affected human health.

The use of contaminated groundwater for drinking and cooking has led to health problems such as diarrhea, hepatitis, and occasional outbreaks of typhoid and cholera.

The inadequate water supply and poor sanitation cause more than 500,000 infant deaths a year as well as high levels of illness and disability in the region. In many countries, cholera is prevalent, especially in those where sanitation facilities are poor such as Afghanistan, China and India.

We need water and we do nothing to not pollutant!!


Title:Benefits of technologies

I. Technologies helps people
A) Work

B) Home

II. Safe time
A) Do your activiies

B) Quick process

Well technology has many benefits. The technologies are important to our everyday I things we find difficult to live without them in this time because they make easier our work and help us to entertainment. Technologies are everywhere.
Technologies help people in many ways one of them is at work. Technologies help you to make your work more accurate and easy. The technologies also help us at home because they do our homework easer too. For example in the kitchen if we had not a can opener would be very difficult to open the can. This technology makes easy this activity but they are more activities technologies could help us.

The technology has many benefits over other of these would be that this saves time because it can make your activities by itself eg cut the grass this activity currently takes a long time and actually are varieties of automatic lawnmowers that do all the work by themselves . The technology will also streamline processes before we used typewriter and if you get a mistake you will start again but now we do everything in the computer that are more practice.
Whatever the technology facilitates our lives and save time they are very important for our work and our home we need it to live in this modern world.

My experience in English 8

Well, at first, this class for me was really boring because I did not understand the things we had to do, like create a blog, how to upload the homework in the blog and things like that. The problem is that I do not like to do homework; I think the class could be better if we do the homework in class with the teacher because I always have a lot of question. However, later the classes start to be more dynamic and less boring because I like to chat in the class and to upload homework’s in the blog.

On the other hand, I learned many things in this level like a lot of vocabulary, how to create a tree diagram; identify the main idea and the concluding sentences. I have to say that it was a great experience because a learned a lot and I meet new friends.

Global Warming

Global Warming is caused by many things. The causes are split up into two groups, man-made or anthropogenic causes, and natural causes.

Natural Causes
Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.

Man-made Causes
Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.

Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation, right? That means more methane because there will be more burning of fossil fuels, and more agriculture. Now your probably thinking, "Wait a minute, you said agriculture is going to be damaged by Global Warming, but now you're saying agriculture is going to help cause Global Warming?" Well, have you ever been in a barn filled with animals and you smell something terrible? You're smelling methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem with the increasing population is transportation. More people means more cars, and more cars means more pollution. Also, many people have more than one car.

advantage and disadvantage of cellphone

Advantages: first, with cellphone you can send messages and you don't need to always call the person. Second you can listening to music this is good because sometimes you have to distrac and finally cellphones are portatil. they are small and you can go with it to wathever part.

Disadvantages: Frist, most of the cellphone are expensive, so not everybady can have one. Second, cellphone sometimes are insecures because if you has one somebody can steal you and finally is easy to make a mistake with cellphones because you can send de message to the wrong person.

earthquake in philippines

Philippine scientists put the preliminary magnitude at 6.5.

The quake was felt in Legazpi city in Albay province, site of the restive Mayon volcano, and southern Leyte province. There were unconfirmed reports of a power outage.

The quake hit at 10:11 p.m. with an epicenter in the ocean 114 miles northeast of Catarman in Northern Samar province, at a depth of 35 miles, said Ishmael Narag, head of the seismology section of the Philippine Institute of Volcanology and Seismology.

No tsunami warning was issued because of the depth of the quake, Narag said.

Edna Meregildo, a government social worker who lives in Catarman, said she was washing the dishes when the ground shook, followed by a power outage.

"It was quite strong. I exclaimed, 'God, please stop this,'" Meregildo told The Associated Press by telephone.

Arvin Unay, a staffer of Northern Samar's provincial disaster management unit, said the quake toppled a vase in his office but no damage was reported in his province.

Cedric Daep, an Albay provincial disaster-response official, said he ordered his men to check for possible landslides triggered by the quake in mountainous areas and in villages at the foot of Mayon volcano, but had heard of no immediate problems


E-mail advantages. Is convenient because you send any time of day or night. For example, in your free time you can send or receive e-mails. You can send everything like PDF files, music, photos, among others. E-mail saves time like e-mail arrives inmediately and you can send everywhere when you´re using the e-mail. Finally. E-mail is easy to stay in touch because you can write to friends easily and edit easily too.

e-mail have some disadvantages. For example, is less personal because you can´t see the person´s face and is not in live. Another disadvantage is easy to make a mistake like send messages to the wrong person and send very personal/confidential information and finally. Need equipment like have a fast computer. If you don’t have a good one the e-mail will be too late and need internet because if you don’t have you can’t send the message.
