Water Pollution

Water is an is very important element that our body need to continue survive. About 70% of an healthy human's body is made up of water. Because of that, you can't live without water more than a week. Lack of water lead to dehydration which reduce the amount of blood and force your heart to pump faster. With dehydration, you start to feel dizzy. Then you start to have a headache, and then fade out. As the result you can die by dehydration.

The best choice to have a healthy body is drink 8 cups of our a day. Drinking too much water is also bad for your body. However, these days, water are being pollute by human activities. Everyday, we do a lot of activities that using water like flushing toilet, wash your car, shower, and have you ever wonder where all of that dirty water will go? In some developed country, that water is cleaned and dumped into the sea. However, in some country that hasn't develop yet, dirty water is dumped into the sea without treated. As the result, the sea water get dirtier every day, and this is the first cause of water pollution.

The second cause also have to do with human daily activities. Everyday human eat and poop.  After you poop, you flush the toilet and the poop travel through a septic tank that connect to your house.  Inside this tank, the solid part and the liquid part is separated. Biological processes are used to break down the solids and the liquid is usually drained out into a land drainage system. From this stage, it can escape into the soil and nearby water bodies.

Moreover, water pollution also cause by other issue such as air pollution. Polluted air mix with mist in air which lead to acid rain.  At this time, all the toxic in polluted air are mix with water in the sea or river. Another main cause of water pollution is the death of sea animal. Dead fish, crabs, birds and sea gulls, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat (living environment).

We can't drink polluted water so we may face a huge problem without clean water. What can we do to solve this issue? The easiest thing you can do is pick up any trash you sea at the beach or avoid throwing trash into rivers or beaches. This will reduce the chance of water getting dirty by human activities. The second think is make sure the septic tank in your house work properly so it will reduce the chance water pollution caused by machine.

Deforestation

Deforestation is when people "cut down trees", or we can say that remove a large area of the forest land for many purpose: selling wood, fuel, selling land and for farming. The negative thing about this is they never re-plant the trees that they cut of.

Let's talk a little bit more about the cause of deforestation. Nowadays, the world population are getting larger. Humans need more space to live, so the first main reasons more people to clear out the forest is for Urbanization. With trees being cut down, we now can construct more buildings, roads,... And as the population grows, human also need more food and it leads to the second cause of deforestation: Agricultural Activities. Agricultural Activities is another main causes of deforestation. They are being cut down for space to grow crops and raise cattle.

In the 21st century, technology improve a lot and people require more than just space and food. Trees are cut down for woods. Woods produce goods like paper, interiors, wood can be use as fuel such as firewood for charcoal. And because of that, we can tell that Logging is one of the reason for deforestation. Human also need oil and coal in their life and that require a lot of forest space for mining. Therefore, Mining can be another cause of deforestation. One of the global issue we have today is Global Warming and it can cause forest fire. Lots of trees are lost after the fire which can lead to deforestation.


With the lost of trees, what is the bad effect for us. Here are a list of effects of deforestation.

- Imbalance Climate: Trees provide water vapor in the air, trees also provide the shade that are needed for the soil to be kept moist. Lacks of trees mean lack of all of the benefits above and this leads to the imbalance of the atmosphere and the temperature.

- Increasing of Global Warming: Trees also utilize the greenhouse gases. With the lack of trees, the amount of greenhouse gases in the air are increased and the Global Warming as well.

- Floods: The tree's roots absorb a large amount water from the rain. Lacks of trees means there are no place for storing the water and easy to cause floods.

- Wildlife Extinction: With more trees being cut down, some animal will lose their habitats and have to move to other places. This is one the cause of animal extinction. We also lost some of the plant by deforestation.


And for me, the solution to this is applying strict rule of forest pioneering. Moreover, we also need to re-plant the tree that we lost for the need of people. Planting new trees is one of the activities that Grade 11 do in the field trip.

Human Trafficking

What is human trafficking

Human trafficking is an illegal crime which  people buy other people to work for them. The people that been sold work as slave. The owner of these people can treat them very bad. They can curse at the "slave", beat them if they want to. Worse, they can outrage and treat these people as sex slave. These owner just doesn't care about the "slave's health" or even worse, they don't care about the life of these people.

Why and how does this happen.

The victim of human trafficking usually have a very poor life condition. They had been promise to to a opportunity to make their life better or  to have a job which doesn't require high level of education. These poor people easily fall in the trap of the criminals. They've been lulled and send to another country to sell as slave. Sometimes, the criminal can just kidnap the victims.

Let's find out about the history of human trafficking.

The 1400s was when the human trafficking started. Portuguese transport people from Africa to Portugal and trade them a as slaves. Later, in the year 1520, the British joined in this slave trading. And as the development of colonies, these slave trading activities increased. In the 1600s, many other countries included Spain, North American, Holland, France, Sweden and Denmark.

Moving on to the 2000s, there was a human trafficking case found in Thailand in 2008.  The victims had been shipped in the seafood container and 57 of them were death because the lack of oxygen. In 2009, there was a trafficking ring busted in Tapei, Taiwan. The were several female had been transported to the U.S using fake passports to make visas. They had been caught by the National Immigration Agency and the U.S. Department of Homeland Security.

And there were many more report of human trafficking. So what is the solution for this. The first solution is paying money to free these slaves. However, you just can't find the exact place to free all of the slave so the second solution can been done easier by educating people around you. You can introduce them to this topic so they can have a better self-awareness.
