Desforestation

Trees make photosynthesis, so they turn carbon dioxide into oxygen. This carbon is stored in the tree and, consequently, when trees are cutted and burned they realese that CO2 into the atmosphere, causing an increase in greenhouse gases.
According to FAO, Food and Agriculture Organization, 25to 30 percent of greenhouse gases that are realesed into the atmosphere comes from desforestation. Despite all the efforts to conserve biodiversity, desforestation continues to grow at a rate of about 13 millions hectares per year, the equivalent to 36 football fields per minute. And we can not forget that trees take thousands of years to grow, so we have to start to planting trees for the next generation.
To reduce desforestation there are some measures that we can take, sush as: increasing the productivity on agriculture areas, so that we don't have to cut trees to make more places to framing; recycle, to reduce the number of cutted trees that origin materials like paper.
