Which of these represents a major ecological problem that was caused by rapid industrial and city growth in the early 1900s? A) air pollution B) urban poverty C) trade barriers D) workers strikes

A) Air pollution

Explanation: This huge evolution of industrialization had a huge effect on the environment and mostly it was pollution. It led to high release of greenhouse gases and at this point industries were not forced to pay fees for the environmental impact that they caused. This occured until the United States appointed the Environmental Protection Agency (EPA) in order to ensure that these industries had limited toxic air emissions and also to control how certain chemicals and gases are released and disposed.

Air pollution

Explanation:

Rapid industrial and city growth brought about great problems in the urban settlement, as there were various dangers to safety and health. Those industrial cities that rapidly expanded were subject to contaminated air and water, and communicable disease at that time was rampant. However poor sanitation led to huge deaths during this period. In the 19th century however, the health condition was improved as a result of better sanitation.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.

this statement is true.

forests are public goods, available for everybody. when usage of such a good becomes interesting for consumers and its usage increases, there can be a risk of overexploitation. it is a non rival good therefore, if one person consumes the good it does not reduce the availability for subsequent consumers.

these caracteristics require the establishment of measures in order to prevent the destruction of a commonly owned space, for example, to restrict the amount of people that have access to the same time.
