Key Concept: Deforestation in India, Legal Framework

a) 0.53%

[Solution Description]

Step 1: Identify the annual loss of forests in India.

The annual loss is given as 3.7 million acres.

Step 2: Identify the total forest area of India.

The total forest area is assumed to be 700 million acres.

Step 3: Calculate the percentage of forest lost annually.

The formula for percentage loss is:

$\left(\frac{\text{Loss}}{\text{Total Area}}\right) \times 100$.

Substituting the values:

$\left(\frac{3.7 \times 10^6}{700 \times 10^6}\right) \times 100 = 0.52857\%$.

So, approximately 0.53% of India’s forest area is lost annually.

Key Concept: Population Growth

d) 40 days

[Solution Description]

To solve this problem, we know that the world population increases by one million every four days. We need to find out how many days it will take for the population to increase by 10 million.

Let’s denote:

$x$ = number of days required to increase the population by 10 million

Since the population increases by one million every four days, we can set up the equation:

$\frac{x}{4} = 10$

Solving for $x$:

$x = 10 \times 4 = 40$ days

So, it will take 40 days for the population to increase by 10 million.
