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 CO 2 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
