Today I'm going to talk about a very seroius topic: Desforestation
And I found a really intresting article about it:
To go to the article Click here
Now a days, the "desforestation is clearing Earth's forests on a massive scale"! There is only left 30% of Earth's forests, imagine in 100 years, how do you think it would be ?
The main cause of desforestation is agriculture, mainly to provide money for families. The agriculture cuts and even burns trees to have more space for their plantation. And in some cases this happens illegally! People also build roads to acess more trees to cut.
The problem is that many of these trees are used to make materials we use in our daily life,such as, paper, glue, and many others, so how do we solve this issue? We need find alternative ways to make these kind of materials we cannot continue destroying our forests, eventhough one day we know they may end if we don't change and stop cutting them.
But not all the desforestation is intencional, some of them happens naturally, like, natural fires.
Like I said desforestation is really bad, not only because it cuts down many trees, but because it also destroys the habitat of many innocent species. It can change the climate too, because when we take out the trees, the soil is exposed and not protect from sun - bloking, so it dries out quickly.
In my opinion, a way to reduce the desforestation, like I alredy said is to create alternative ways to produce, materias made of trees(wood), but also balance the desforestation, and replace the trees that we cut off. The replacement of trees already happen, but it's not enough to replace all the trees we already killed!
My conclusion is that trees are very important and should not be cutted off!!!

#2 Pollution!
To go to the site Click Here
I choose this topic, because it´s affecting a lot our world, and damaging it.
Pollution is a introduction of a contaminant to a natural environment, but as some people may think, not only humans that are responsible for all the pollution in our planet. All animals when they breath, release carbon dioxide, that cause partially affect air pollution and damage the planet atmosphere.
There is not only one type of pollution, there is: air pollution, land pollution, sound pollution, light pollution and finally water pollution.
The land pollution, is the type of pollution all of us contribute, the house or industrial garbage. But depending where this gargabe is going, it can damage or benefit the environment. If it´s destination are dumps and landfills, it going to damage ( a lot) our environment. It can also happen that garbage ends up on rivers, causing water pollution.But the ones that are collected for recycle are going to benefit the planet, by reusing the materials and not polluting.
Water pollution happens when solid or chemicals are introduced to the water. An example is on places where have agricultural production that uses pesticides and fertilizers, and it happens surface runoff, making all the fertilizers go into the water. This type of pollution may affect on marine life, animals may not distinguish garbage from food and eat it, by accident.
The air we breath have the same composition, but when they are added differently, it happens the air pollution. Like I said in the begginning, animals contribute for the amount of carbon on the atmosphere, but that don´t change much, the factor that affect very dangerously our environment, are: cars, industries, planes, etc.
The noise pollution happens when sound coming from cars, industries, planes, motorcycles, reach a really high level. These sounds can affect our health, by causing stress, high blood pressure, etc. But this noises do not only affect land, it can also affect marine animals, by the noise of ships. It even kill some marine species that depend on natural underwater world.
And finally the light pollution. The light, I think that on this point the human beings cannot imagine life without it. But for the other species in our world, that light can really harm them, specially the birds, that with the presence of artificial light, they sing and eat at different hours they are suppose to. And the turtles. The new born turtles that just hatched their eggs use starlight reflected on the waves to go to the ocean, but with the lights on, in the street they can confuse their way, and go in the wrong direction. This turtles can even die, when a car hits them.
And the conclusion is that, we need to take care of our planet. We need to avoid more pollution. For that we can, recycle our garbage, turn off the lights when we are not using them, instead of gasoline, use alcohol, that pollutes less, and don't trow trash on rivers. If we do that, we can live in a BETER WORLD!!!

#1 Improve your brain with music!!!
To go to the link Click here
I`am going to talk about a science article, if you want you can check it on the hiperlink above.
Do you love music?
Your parents don`t let you listen to music while doing homework or studying?
Well, this article is directly for you.
I also love music that why this article really interested me, and now i`m sharing it with you guys.
First of all, listening to enjoyable music makes you learn better. So that might mean that studying while listening to music is NOT a bad thing. It also helps connecting the two hemispheres of the brain. How? You might be wondering. Well, the brain just like I said is divided in two, the right hemisphere and the left hemisphere. The right hemisphere is responsible for the creativity and your artistic side, the left hemisphere is responsible for your language and math. So if you listen to music with rhythm and lyrics it will stimulate both sides of your brain, the rhythm your right and the lyrics your left.
It also helps by making you more creative, and stimulate dreaming, learning and relaxing. But for that to happen you need to listen the type of music you most enjoy. But scientists have proved that if you listen to classical music it stabilise your blood pressure. It can activate positive emotions.
Music is so incredible it can help people who suffer of Alzheimer. This disease damage your memories, but if you listen to music it can stimulate your memory, improving brain functioning.
Well, the conclusion of all of these is that MUSIC IS VERY IMPORTANT!!!
