Currently the global economy consumes roughly 15 billion cubic feet of hardwood per year. This is nearly 2.5 times the amount of hardwood consumed annually in the 1950s. This causes a number of environmental issues, including loss of watersheds, destruction of habitats, increased air pollution, and landfill crowding.
Global hardwood consumption is expected to steadily increase, growing by roughly 20% in the 2010s and by more than 50% by 2050. The effects of the growth will be devastating to the world’s hardwood forest. It is estimated that currently 10 times more trees are lost annually to wood consumption than are replanted, resulting in a net destruction of 40 million forest acres annually.
All wood consumption flows through two industry paths: construction use and stationery consumption. Construction use wood begins at sawmills and becomes lumber, plywood, veneer, wood paneling, construction material, and furniture stock. Stationery wood goes to the paper mills and becomes paper, cardboard, and fiberboard.
Generally, 50% of all cut hardwood goes to sawmills for wholewood projects; 20% goes to chip mills for fuel consumption, particleboard creation, and other semiwood products; and the remaining 30% goes to pulp mills. Unfortunately, roughly 25% of the wood that is cut never actually reaches consumers, because wasteful manufacturing practices render it useless and send it straight to landfills.
The United States is the greatest global consumer of hardwood products, using more than 17% of the 15 billion cubic feet cut annually. This is roughly twice the consumption rate of other industrialized nations and three times that of developing countries.
The average American consumes 886 pounds of paper per year. This is twice that of most European residents and more than 200 times that of Chinese persons, who consume only 3 pounds of paper per year.

Kindly explain the answer to question 1
Official Explanation
The amount of hardwood, in cubic feet, consumed annually by the United States, other industrialized nations, and developing countries.
Source #1 indicates the total amount of hardwood consumed annually by the global economy, 15 billion cubic feet. Source #3 indicates the annual consumption rate for the United States, other industrialized nations, and developing countries. Enough information is provided to calculate the actual amounts consumed annually in cubic feet.
Answer: Yes
The amount of paper, in pounds, consumed annually by residents of most European countries
Source #3 provides the information necessary to determine the second item. The average American consumption amount is provided: 886 pounds of paper per person per year. This is twice that of most European residents, so the European amount can be calculated.
Answer: Yes
The amount of hardwood cut annually, in cubic feet, that goes to sawmills for whole-wood projects
The third item can be determined by the information provided in Sources #1 and #2. Source #1 indicates the total amount of hardwood consumed annually in the world, and Source #2 gives the percentage of this amount that goes to sawmills for whole-wood projects.

Sajjad1994 Ques 1, In source 3 it mentions "The United States is the greatest global consumer of hardwood products, using more than 17% of the 15 billion cubic feet cut annually". Here it says more than 17% & does not give the actual % , then how can we calculate the exact amount ?

I have the same question. Also, in the second question, the question states 'residents'. And source 3 talks about per person consumption. How can we calculate the total for European residents based on per person data? We do not have the population info here. Or am I misinterpreting the qs here? Let me know

I dont think the second answer is correct. We do not know the population of European countries, how can we calculate the total amount of hardwood used by European countries?

The actual amount is given in Tab 1.

It doesn't give the exact rate, it says that the rate is more than 17%, meaning that:

Sajjad1994 In Q1) The text mentions that "using more than 17% of the 15 billion cubic feet cut annually. " That means the amount will be greater than 15 billion x 0.7 but we cannot calculate the actual amount. Same goes for the industrialised and developing nations
In Q3) The text mentions that "Generally, 50% of all cut hardwood goes to sawmills for wholewood projects". Hence, we can't be sure of the exact amount.
Can you please point me where am I going wrong. Thanks in advance!
