Deforestation

There are many different natural problem are happening now in the world. You can see that there are many organization and revolution come out to protect and improve the environment issues. One of the very popular and dangerous issues is Deforestation.
So what is deforestation? This is the destruction of natural due to human activities like logging, cutting trees for fuel, slash-and-burn agriculture, clearing land for livestock grazing, mining operations, oil extraction, dam building, and urban sprawl or other types of development and population expansion.An estimated 18 million acres (7.3 million hectares) of forest — roughly the size of Panama — are lost each year, according to the United Nations' Food and Agriculture Organization (FAO).
What is the cause of deforestation? People usually cut trees for sell, housing, urbanization, timber,. and they don't know how important those trees are. First,deforestation happens can lead to the loss of species, animals will lost their "home", some might die, and this lead to animal extinction, also, smaller plant will die too.Next, carbon emissions,trees help absorb greenhouse gasses and carbon emissions ( by human civilization and contribute).The loss of a big amount of tree will make the carbon and greenhouse gasses enter the atmosphere. Third, soil erosion, the soil can dry out, leading to problems like increased flooding and inability to farm.Soil erosion can also lead to silt entering the lakes, streams, and other water sources. This can decrease local water quality, contributing to poor health in the local population.
What can we do to help? You can apply yourself into many organization that urges people to plant and protect the tree. Persuade and tell everybody about this issues. Also, i think that the government should have stricter laws to decrease this issue.Schools should have more assembly or study about the trees and the importance of it for children to understand it when they was younger.
