Why is pollution never a strictly local problem

Answers

Answer 1

Answer: Because there are many types of pollution.
Air pollution, water pollution, etc.
The reason it is never local is because it's a chain reaction to the environment.
Example 1:
China has the worst air pollution in the world from factories and cars. The smoke has a depleting effect on the O-zone layer which protects humans from the sun's harmful UV rays. Also, without the protection of the o-zone layer, global warming is increased (yes, it's real) and glaciers begin to melt raising water levels and so forth. So even though the smoke is all the way in China, it affects all of us living on earth.
Example 2:
Let's say there is a oil spill in the ocean which potentially kills or endangers many organisms, like fish. Even though the oil spill was only in that part of the ocean, it affects all the animals because of something called the food chain. If all of a certain fish or animal dies out and that was another animals primary source of food, then it messes up the chain.

If you have a heat engine with a hot reservoir of 515°C and a cold reservoir of 190°C, what is the thermal efficiency of the system?

Answers

The equation for the thermal efficiency of a system is given by n = Tc/Thx100 where n is the thermal efficiency, Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir. Dividing 190 by 515 gives us an efficiency of 36.9%.

Suppose scientists could compare the DNA of modern humans from around the world with the DNA of Homo erectus populations from the humans’ native homelands. If DNA samples from each modern human were found to be most similar to the Homo erectus DNA from their homeland, that finding would__________________. a. support the multiregional model.. b. support the out-of-Africa model.. c. support both the multiregional model and the out-of-Africa model.. d. disprove both the multiregional model and the out-of-Africa model.

Answers

A. Support the multiregional theory as it would suggest that the evolution from homo erectus had happened naturally across the globe.

Answer: The correct answer for the blank is-

a. support the multiregional model.

Multiregional model is a scientific model that provides explanataion of pattern of evolution of modern humans. It is an alternative explanation of Out of Africa model.

According to this model, modern humans that are present around the world (that in various regions or multiregions of the world) show similarity to the Homo erectus found in Africa.

In other words, species of human beings first originated in Africa as Homo erectus, which then underwent subsequent human evolution upon dispersing in various regions around the world. These species include all archaic forms of human like Homo erectus, Neanderthals, and evolved worldwide as Homo sapiens ( modern human forms).

Thus, option a) is the right answer.
