Answer

From 2005 to 2011, the money spent on conserving biodiversity exhibited an overall increase.

Initially, in 2005, the spending was approximately 470 million pounds, and by 2008 it peaked at around 690 million pounds, marking a growth of about 220 million pounds over three years. After 2008, the spending decreased, with a notable drop to approximately 630 million pounds by 2011.

Step 2

Calculate the percentage decrease in the money spent on conserving biodiversity from 2013 to 2017.

Answer

To calculate the percentage decrease:

Money spent in 2013: 690 million pounds.
Money spent in 2017: 460 million pounds.

Using the formula:

$\text{Percentage decrease} = \left( \frac{690 - 460}{690} \right) \times 100$

Calculating this gives:

$\text{Percentage decrease} = \left( \frac{230}{690} \right) \times 100 \approx 33.33\%$

Rounded to two significant figures, the percentage decrease is 33%.
