Deforestation by burning has been described as a "double whammy" to the environment, meaning it has 2 negative impacts. Why is this description accurate? 

• Forest burning releases CO₂ while decreasing oxygen, which disrupts cycles
• Deforestation reduces the amount of oxygen in the atmosphere, which depletes the ozone layer
• Forest clearing is often followed by land development, which often leads to increased noise pollution
• Deforestation increases the number of plant and animal species by destroying habitat
