Question

why the amount of carbon dioxide in the atmosphere is increasing? give four reasons​

Answer 1

Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.

Answer 2

:

first of all thanks for asking this question!! and here is your answer mate ♥️

Explanation:

Consuming electricity: Burning fossil fuels emits CO2, with coal releasing twice as much of the gas as petroleum. Worldwide, fossil fuels generate 85 percent of electricity. The number of coal-burning plants will increase as China and India continue to industrialize. Currently, 41 percent of CO2 emissions in the U.S. arise from generating electricity.

Transportation: Whether for business or pleasure, locomotion is the second largest source of U.S. CO2 emissions. International travel is also a factor. A study of cruise ships found that vacationing at sea emits 12 times more CO2 than vacationing on land. The 11-day international Copenhagen Climate Change Conference in Denmark generated 41,000 tons of CO2. U.S. delegates alone produced enough CO2 to fill 10,000 Olympic swimming pools.

Building: Industrial manufacturing emits lots of CO2, but it only accounts for 2 percent of U.S. emissions. Iron and steel manufacturing and cement production are the biggest offenders. These industries consume monumental quantities of heat energy to convert raw materials into construction products.

Deforestation: Trees are potent organisms for absorbing and removing CO2 emissions from the air. Cutting them down stops that process. Although deforestation is a minor source of increased CO2 in the U.S., loss of forestlands account for 20 percent of global CO2 emissions. Burning trees for fuel and natural decomposition of forest material also release CO2.
