Sometimes when I have my morning coffee, which I drink black with no cream or sugar, I notice a thin film floating on top of the

coffee. Since I have just read Chapter 3 of the text, I now realize the nature of this substance and so I run to my friend screaming, "Look at this ________ in my coffee!"

Briefly summarize the environmental problems facing South Asia.
faltersainse [42]
1. Endangered species conservation

The problem: Southeast Asia sits almost entirely in the tropics, and as such, is covered in rich, dense, biologically diverse jungle. As a result of a wide number of factors — from poaching to deforestation — many native species are endangered. 

2. Air pollution

The problem: Air pollution is a global problem, but Southeast Asia does have among the worst air pollution in the world, only behind East Asia and Indiasrc. The region is prone to relatively frequent “hazes,” which are the result of widespread fires. These fires are generally started intentionally by either small-scale farmers or companies trying to clear land of trees so they can exploit it the following year.

3. Destruction of coral reefs

The problem: Southeast Asia is known for its incredible coral reefs, and, subsequently, its incredible diving. The area known as the “Coral Triangle” — mostly centered on the islands of Oceania — is the most biologically diverse marine environment in the worldsrc. Unfortunately, the reefs of Southeast Asia have been seriously degraded over the past several decades.

This is the result of several factors: First, the ocean absorbs about a quarter of all the carbon dioxide we put into the atmosphere each yearsrc. While this actually helps reduce the effects of global warming temporarily, it also means that more of that carbon is going to be converted into carbonic acid, increasing the ocean’s acidity level over time. This acidification fundamentally weakens coral reefs, making them more prone to disease, and less likely to recover from disturbances.

The second factor is overfishing. Not only does the widespread removal of fish species harm the coral reef ecosystem, but many of the methods used to catch the fish harm the system itself, such as blast fishing (the use of dynamite), and cyanide fishing (using sodium cyanide to stun the fish and capture them for personal aquariums).

A third factor is actually dive tourism. When divers visit coral reefs, they’ll often interfere with the ecosystem in a way that can damage it — whether by walking on the reefs or taking specimens home for themselves.

4. Deforestation

The problem: As cities and populations grow, more land area is needed. Often, this area is created out of forests. In Southeast Asia specifically, given its position in the tropics, much of the forest that’s destroyed is rainforest, one of the most biologically diverse ecosystems on the planet. Rainforests are not only home to more than half of the world’s plant and animal speciessrc, but they also provide over a quarter of our natural medicinessrc, and they absorb over a quarter of our planet’s carbon dioxidesrc.

So naturally, the effects of deforestation of rainforests can be catastrophic — not only does it destroy plant and animal habitats, but it also accelerates climate change and potentially deprives us of undiscovered life-saving medicines. 

5. Water security

The problem: The world as a whole may well be close to reaching “peak water,” the point where we start consuming fresh water faster than it can be replenished.

6. Increased urbanization

The problem: Southeast Asia is not immune to the global shift away from rural living and towards city living, and this shift carries a good number of potential environmental consequences, especially if it’s not guided by smart and sustainable policies. Urbanization can result in overcrowding, pollution, poor sanitation, and political instability — which in turn could lead to violent conflict, which is never good for the environment. Additionally, if cities are planned poorly, massive urban sprawl is often the result, which in Southeast Asia would bring about more deforestation, habitat destruction, and carbon emissions.

During the 1970s, the military junta in power in Greece initially selected candidates for officers based on their submission to
faust18 [17]

Answer:C) compliance; acceptance

Explanation:

Comply is a term that refers to obeying the rule or the order you are given even if you don't agree with it.

Compliance then begins from abiding by the rules or orders and individual do this publicly while they may still hold on to their own beliefs in private.

Over time people may start to believe in these beliefs that they have been adhering too in such that they begin to accept them as one of their own also and this is acceptance.

Officers in Greece started by complying to the authorities and then over time might have began to accept these as their own beliefs.
