What has deforestation contributed to the increase in CO2?

Best Answers

Carbon dioxide is a greenhouse gas. It absorbs heat energy that is radiated from the Earth's surface and prevents it from escaping into space. This keeps the Earth warmer than it would otherwise be. But human activities are increasing the amount of carbon dioxide in the atmosphere. read more

During the process of photosynthesis,trees can absorb the CO2 from the atmosphere and utilize it in food making. So, if deforestation occurs then rate of photosynthesis decreases and no CO2 is absorbed by the plants . In this way,deforestation contributed to the increase in CO2. read more

By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the world’s roads. According to the World Carfree Network (WCN), cars and trucks account for about 14 percent of global carbon emissions, while most analysts attribute upwards of 15 percent to deforestation. read more

Deforestation would cause more water to evaporate. It will stay in the atmosphere as water vapor. Water vapor , however, has a more potent effect to climate than CO2 does because water vapor itself is a greenhouse gas. It holds more heat than carbon dioxide. read more

Deforestation has an adverse affect on air by reducing the amount of oxygen and increasing the amount of carbon dioxide as well as contributing to global warming. Fewer Trees to "Clean" the Air Trees and plants, in general, produce energy for growth using a process known as photosynthesis. read more
