1. 서론
공기. 물과 더불어 토양은 인간을 포함한 생물의 생존에 필요한 중요한 환경 요인이다. 토양은 단순히 인간활동의 기반을 제공하는 것이 아니라 유해화학물질을 여과, 흡착, 분해 또는 변환시켜 정화 작용을 하므로 지하수의 오염을 막거나 먹이사슬을 통해 유해불질이 동물이나 인간의 생
Concept
Runoff election is a voting system used to elect a single
winner where the voter casts a single vote for their chosen
candidate.
If no candidate receives at least a minimum percentage of
the vote in the primary election, there will be a subsequent
run-off election between the top two vote getters to
determine the party candidate.
The run-off election allows a selecti
runoff from highways, and untreated human waste. When this waste dumped into rivers, the water downstream becomes undrinkable and unusable for agriculture, and also kills plant and animal life in the rivers.
Clean air and water is a prerequisite not only for human life, but also for all life on the planet. But air is now being polluted by modern transportation, notably gas-powered automobiles, as
runoff.
Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.
A third process by which salinity may be altered is associated with the formation and melting of se

2. Solutions & Implementation
As explained earlier, GE implemented a strategy, Ecomagination, to cope with the environmental challenges. Ecomagination is made up of very real goals that GE strives to reach thro

The State of the World's Health / 세계의 건강 상태
Individuals regularly make decisions about their physical and mental health. They do this partly because a serious illness can have a devastating effect on a person and on his or her family. Similarly, just as the health of a family is connected to individuals within that family, the health of a nation is clearly connected to the
