Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which environmental concern is most associated with burning fossil fuels?
A
global climate change
B
pollution of ocean waters
C
ozone layer destruction
D
decrease in levels of atmospheric carbon dioxide
Explanation: 

Detailed explanation-1: -When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

Detailed explanation-2: -The primary issue associated with burning fossil fuels is that the practice releases large quantities of greenhouse gases into the atmosphere. High concentrations of greenhouse gases in the atmosphere increase the global temperature and cause climate change.

Detailed explanation-3: -But burning them creates climate change and releases pollutants that lead to early death, heart attacks, respiratory disorders, stroke, asthma, and absenteeism at school and work. It has also been linked to autism spectrum disorder and Alzheimer’s disease.

Detailed explanation-4: -Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat.
