Firlakuza [10]
<span>The answer is Leukoplakia. When you have this condition, there is a thickened, white patches that form on your gums, the interiors of your cheeks, the bottom of your mouth and, occasionally, your tongue. These patches can't be scratched off. Specialists don't know what the source of leukoplakia is but consider chronic irritation from tobacco — whether dipped, smoked, or chewed — to be the main reason in its development. Most leukoplakia patches are noncancerous meaning that they are benign, though some show initial signs of cancer. Cancers on the bottom of the mouth can happen next to areas of leukoplakia. And white areas varied in with red areas (speckled leukoplakia) may specify the potential for cancer. </span>

Why is the environment’s ability to meet present and future needs directly related to technology and social organization?
ololo11 [35]

Answer:

The correct answer is option D. "I, II, and III".

Explanation:

The environment’s ability to meet present and future needs is directly related to technology and social organization:

I. Environmental impacts depend on population density. The higher the population density in a region, the more likely it suffers from environmental impacts caused by people's bad practices.

II. Affluence determines people’s level of consumption, and hence, their environmental impact. People with great affluence are more likely to cause major environmental impact, has they consume more products and have luxuries such as private air and water transportation which generates environmental impact.

III. Modern technological advances have made it possible for humans to significantly alter planetary systems. For instance, human satellites produce space debris, which can possibly alter planetary systems.
