Sources of Carbon Dioxide and Environmental Issues

The rapid increment in the anthropogenic activities has enhanced carbon dioxide (CO2) emissions and has given birth to pressing environmental issues worldwide. CO2 imparts a significant role in global warming that leads to global climate change. The increased dependency on fossil fuels, in the form of coal, oil and natural gas, has raised the concentration of CO2 in the atmosphere from 280 ppm to 413 ppm. In the past decade, the CO2 emissions were taking place at the rate of 2 ppm/year and has led several risks to human life including glacier melting, floods, heat waves, droughts, cyclones, hurricanes, and food security issues. Countries like China, United States, India, Russia, Japan, Korea, Germany, Iran, Canada, United Kingdom, and others contribute the lion’s share in global CO2 emissions.
