  • Genetic engineering, sometimes called genetic modification, is the process of altering the DNA? in an organism’s genome?.
  • This may mean changing one base pair? (A-T or C-G), deleting a whole region of DNA, or introducing an additional copy of a gene?.
  • It may also mean extracting DNA from another organism’s genome and combining it with the DNA of that individual.
  • Genetic engineering is used by scientists to enhance or modify the characteristics of an individual organism.

The occurrence of these stranded ice masses is thought to be the result of gradual accumulation of outwash atop the irregular glacier terminus.

An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation, known in popular terminology as the Ice Age.[1] Individual pulses of cold climate within an ice age are termed "glacial periods" (or, alternatively, "glacials", "glaciations", "glacial stages", "stadials", "stades", or colloquially, "ice ages"), and intermittent warm periods within an ice age are called "interglacials" or "interstadials", with both climatic pulses part of the Quaternary or other periods in Earth's history.[2]


In the terminology of glaciology, ice age implies the presence of extensive ice sheets in both northern and southern hemispheres.[3] By this definition, we are in an interglacial period—the Holocene. The amount of heat trapping gases emitted into Earth's oceans and atmosphere are predicted to prevent the next glacial period, which otherwise would begin in around 50,000 years, and likely more glacial cycles.[4][5]

Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.
