Deforestation by burning in the Amazon rainforest 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 in the Amazon is often followed by land development, which often leads to increased noise pollution

• Deforestation in the Amazon increases the number of plant and animal species by destroying habitat
