Forests cover about 31% of the land on Earth, but, sadly, that number is decreasing at a rapid rate. Deforestation, human-driven and natural loss of trees, is one of the main causes of this depletion. A natural loss of trees might come from a fire, for example, but deforestation done by humans is more common and involves removing trees to make room for something else. This can include clearing the land for farming or using the wood from trees for fuel, construction, or manufacturing. Despite these potential economic benefits, deforestation should be stopped because forests are too important for people, animals, and the environment.
Write three to five sentences explaining how the author develops the key concept in this paragraph.

Answers

Answer:

The author develops the key concept by first talking about how much forest covers land on the earth and then stating that it is decreasing at a fast rate. He then explains how deforestation is happening. The author then goes on to talk about how the main cause of deforestation, how he feels about it, and how it should stop. The key concept is that humans are causing deforestation and its terrible for the environment.

Explanation:

Dont use exact words

The fundamental idea is developed by the author by first discussing how much forest covers the earth's area and then emphasizing that it is rapidly disappearing. Then he describes the process of deforestation. The author continues by discussing the primary reason for deforestation, his feelings toward it, and how it should come to an end. The fundamental idea is that human activity is creating deforestation, which is bad for the ecosystem.

What is Deforestation?

Deforestation, also known as forest clearance, is the removal of a forest or tree stand from the land before it is put to another use other than that of a forest. Conversion of forest land to farmland, ranches, or urban usage is a kind of deforestation. Tropical rainforests see the highest concentration of deforestation.

In barely one century, half of the world's rainforests have been devastated. The world's rainforests would vanish in 100 years if we do nothing and present deforestation rates continue.

Because there are fewer trees to absorb carbon dioxide, this greenhouse gas builds up in the atmosphere and hastens global warming. The biodiversity of the planet is also at risk from deforestation. There are numerous animal and plant species that may be found in tropical woods.

Explanation:

Answer:

c

Explanation:

Which of the following best describes how the author organizes the reasoning of his argument in the opening lines of the passage(“warned by the disaster....ever adopted by the nations”)?

Answers

Answer:

B: Tracing a sequence of events resulting in a positive outcome

Explanation:

(AP Classroom) Correct. Writers frequently use certain recognizable approaches to develop and organize the reasoning of their arguments. In the opening lines of the passage, the author employs such a method of development when he traces a sequence of events that he believes have culminated in a positive outcome: the First World War happened; the war provided a cautionary example; world leaders have been trying to prevent another outbreak of war; in the end, they succeed in devising the “greatest preventive measures ever adopted by nations.” A method of development provides an audience with the means to trace a writer’s reasoning in an argument. In this case, the author’s approach to organizing his argument suggests that he understands recent peace preservation efforts in terms of a temporal chain of events—one in which each event is linked to the next by a causal logic.

The option that best describes how the author organizes the reasoning of his argument in the opening lines of the passage is;

Drawing parallels between the current situation and a past crisis

The proper organization of texts helps readers to follow the sequence of events being described by the author.

In the opening lines of the passage, the author's word choice shows that he was drawing parallels from an event that was earlier discussed in the text.

It makes reference to the World War 1 disaster that had occurred before and draws parallels from the lesson that world leaders learned from it.

Thus, parallels are made between a past and a current event.

Answers

Answer: She found her cabin still dry, but as she rummaged about, she heard a key turn and suddenly realized the steward was locking the stateroom door to prevent looting.   This is the excerpt that best supports the idea that there is a sense of mistrust on the ship because the caption or somebody who is in charge of the ship probably thinks that the passengers will try to escape their own room to go into another person's room and steal one or a few of their possessions from their original owner, so in able to stop that from happening, the person in charge told the stewards to lock their doors.

Explanation: When Assistant Second Steward Wheat noticed Chief Steward Latimer wearing his lifebelt over his greatcoat, he urged the Chief to put it under the coat—this made swimming easier."

This one is just talking about the Assistant SSW noticing that CSL was wearing his lifebelt the wrong way and has nothing to do with trust and the ship.

"The water was slowly crawling up the stairs, and from time to time Lightoller walked over to the entrance and checked the number of steps it had climbed."

I think this one is talking about how the flood that was happening begin to make its way up the stairs. This one doesn't have anything to do with mistrust. If it was, I'd think that it would be talking about the people themselves on the ship, not how water is flooding in.

"An old lady made a big fuss at No. 9, finally shook off everybody, and ran away from the boat altogether."

This one is about a lady making a fuss and running away from everyone since maybe she has had a enough and she's probably a bit overwhelmed and such by what is happening. It's not a matter of mistrust, it's just that she felt the need to get away before everything became a bit too much for her even more.

Explanation:

thats a good movie

Answer:

Explanation:

In chapter eight of The Hobbit by J.R.R. Tolkien, Bilbo and the dwarves are still on their journey. Things are not quite as fun as they were in the beginning, though their travels now do seem more purposeful. As the group travels, they have to be aware of every physical hazard as well as the many enemies that are everywhere around them.

After a bout with spiders in which Bilbo is the hero and after which he reveals to his companions that he has the ring, the adventurers are all feeling rather drained and stop to rest. In fact, they all sleep quite soundly; only in the morning do they realize that Thorin is missing.

Thorin was captured by the wood-elves who were camped nearby (something the travelers should have known because they saw the lights last night). The wood-elves are naturally suspicious and distrustful, but they also have a deep dislike for dwarves. Thorin Oakenshield, "son of Thrain son of Thror King under the Mountain," is the one who got caught.

Thorin is the brave leader of his band of dwarves, a philosopher of sorts.

The phrase a la carte is foreign. It is a French expression used when you can order items on a menu separately instead of as a set meal. When we use words or expressions such as this one in writing, we should italicize them. Italics will distinguish them, showing they are written in their original language.
