The two LANDSAT images on the next page show forested area in Chile and were taken in 1986 and 2000 (images courtesy of the European Space Agency and NASA). 
The images are in false colour: 
•	red colour shows near infrared reflectance 
•	green shows red reflectance and blue shows green reflectance-

1)	Can you identify the areas where trees have been removed between 1986 and 2000? Why do you think there are no trees in those areas in 2000?

2)	Can you identify the areas where trees have appeared?

3)	Explain why these changes have occurred.

4)	Can you spot any changes in the agricultural fields of the area?
