Hi! today I will talk about the glaciers.
They are very important for all the people because they are one of  the principal spring of sweet water.
In the last years the glaciers are melt, this raise the sea level. If the sea level raise much many place on the Earth will be flood, and many people will be affected (they lose their houses, their jobs, etc).
The glaciers give origin to many rivers. If the glaciers melt completely, many rivers will dry up, and many farmers will be affected for this. If the farmers are affected all the people will be affected because the vegetals die without water.
Also the economy will affected because many things will be more expensive.
All the Earth will be affected if this happen.

I think we must be conscious with this, because without water we can't live.
In my reflection I ask ¿why the glaciers are melt? and I searched in internet, and I found this article: http://ac.els-cdn.com/S0921818106003031/1-s2.0-S0921818106003031-main.pdf?_tid=96660ada-eb61-11e3-a8a5-00000aacb361&acdnat=1401829192_6217b6a36a915576bafd71ace4c38dd2  here I found some reasons, and the people (the human race) is the principal reason.
This is very very very important because if all the people change some things about their lives we can stop the melt of the glaciers.
I like this topic because is important for all people, animals, trees, vegetals and all the live on the Earth.
