No Forest No Oxygen
Nitish Priyadarshi

Deforestation, or the removal of forests, is a major problem that has devastating effects all over the world. Europeans began clearing forests more than 500 years ago. The invention of modern machinery made the process even easier. By the end of the 19th century, most of the deciduous forest of North America, Australia and New Zealand had been cleared. In the 21st century, tropical forests are being cut and burned at alarming rates in South America and Southeast Asia. Asia as a whole has already lost about 90 percent of its forests.
With forest resources--"the lungs of the Earth"-- under attack in many regions, some have raised concerns about the planet's oxygen supply.
