Question
Chapter 53, Problem 13PIAT
Summary Introduction
To review:
The increase and/or decrease in the productivity of the Amazonian forests as a result of increasing carbon dioxide due to the burning of fossil fuels.
Introduction:
The atmospheric gases like CO2, methane (CH4), ammonia (NH3), water vapor, nitrous oxide (N2O), and chlorofluorocarbon (CFC) are known as greenhouse gases (GHGs). They trap the outgoing solar radiations and increase the temperature of the atmosphere. This phenomenon is known as greenhouse effect (GHE).

Explain how building roads into previously inaccessible forests can harm the forests. Distinguish amongselective cutting, clear-cutting, and strip cutting in he harvesting of trees. What are two types of forestfires? What are some benefits of occasional surfacefires?
Forests take in carbon dioxide from the air, thus it is called “carbon dioxide sinks” or “carbon sinks”.- What is the use of carbon dioxide in the forests? Explain.
Discuss the possible role of forests in the control of CO2.

The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2.
