- Alternative Energy
Generally refers to energy sources other than conventional sources of fossil fuels, such as solar and wind energy, that are renewable and environmentally friendly. These not only create less pollution but are necessary developments in the face of the Earth's quickly depleting supply of fossil fuels (e.g. oil, natural gas, coal).
- Alternative Fuel
Fuel from a source other than the conventional sources (fossil fuels, coal, propane, natural gas), which are nonrenewable and associated with global warming. Some alternative fuels include biodiesel, hydrogen, ethanol and vegetable oil, with more being developed all the time. Also known as non-conventional fuel or advanced fuel.
- Alternative Transportation

The southernmost continent on Earth, about 98% covered by ice and home to a unique assortment of marine wildlife and plants as well as penguins and seals. There are no permanent human residents, but tourism and scientific research bring thousands a year to its icy shores. As global warming rises, this pristine continent is in grave danger, as is the rest of the world with ice-shelves breaking off and causing sea levels to rise at an alarming rate.
The region around the North Pole, this unique ecosystem consists of deep ocean covered by drifting pack ice. One of Earth's last pristine regions, it is home to a vast array of sea life, plants, mammals, birds and of course Santa Claus. It also stores a wealth of natural resources, including fresh water and fossil fuels. The Arctic region is threatened from all sides: overfishing, toxic pollution, oil drilling... and oh yes, it's shrinking away due to global warming, which is a problem for the whole planet.
The layer of gases that surrounds the earth. It is made up of different layers according to how far away from the surface of the Earth it is.
