Describes any form of precipation with an unusually low pH value. The low pH value is the result of pollutants, such as sulfur dioxide and nitrogen oxide, which chemically alters water droplets. The burning of fossil fuels increases occurences of acid rain.
The presence of unnatural human products in the atmosphere as a result of human activities (e.g., the presence in the air of the by-products of burning fossil fuels).
The forgiveness of debts in exchange for setting aside land for conservation or preservation; this swap is of interest to many less developed countries that have tallied up large debts to more developed countries and feel pressure to repay them.

The gradual warming of the Earth's atmosphere due to pollutants (greenhouse gases), primarily from more developed countries, which keep the warmer air closer to the Earth's surface.
These resources take thousands of years to be produced and cannot replenish themselves.
A controversial form of alternative energy, _______ _____ needs the nonrenewable resources such as uranium or plutonium for its production and creates long-lasting, dangerous waste products. It is, however, the most powerful energy source known.The two types of this power are fission and fusion.
Resources that have the ability to replenish themselves in nature relatively quickly, thereby being infinitely available to consumers.
The eventual depletion of the fossil fuels on which energy-dependant economies rely heavily.
A mine in which tunnels are dug horizontally under the surface of the Earth and shafts are placed deep into the Earth.
The use of the sun's heat to create electricity. It is one of the best renewable resources available because of its accessibility and cleanliness.
The killing off of landscape to built a new one, ________ uses land for economic purposes in the sense that the intention is to destroy the previously existing landscape.
Tragedy of the Commons
Garrett Hardin's term for the idea that humans will inevitably do what is best for themselves despite what is best for the public good.
