Deforestation of areas considered to be rich sources of genetic material could limit future agricultural and medical advances due to

• the maintenance of dynamic equilibrium 
• the loss of biodiversity 
• an increase in the ecosystem’s carrying capacity
• the depletion of the ozone layer

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

A large tract of land is purchased by a commercial agricultural company. The land is cleared of its native flora (plants), and a single crop is planted instead. What is the effect of this action?

• There is an increase in the variety of foods.
• The biodiversity of the area is reduced.
• There is a reduction in the size of the land
• The cost of the planted crop increases

Many common products, such as wooden furniture, paper, and books, are made from trees. Which of the following is a likely consequence of humans cutting down a forest in order to make use of the natural resources there? 

• the decrease of chemical runoff into the oceans
• increased acid rain
• the increase of light pollution in cities
• the destruction of habitats

Human activities that degrade ecosystems result in a loss of diversity of the living and nonliving environment.  Two ways in which humans frequently harm ecosystems and affect other organisms is through land use and pollution.

How does land use cause a reduction in biodiversity? 

• It decreases the space and resources available to certain species
• It causes herbivores to become carnivorous
• It provides a more hospitable living environment
• It causes all the natural Earth cycles to stop
