Climate change
The Earth is warming at an alarming rate in recent years due to cumulative excessive heat-trapping emissions of greenhouse gases such as carbon dioxide and methane to the atmosphere. Agriculture and other human activities that require fossil fuels combustion since industrialisation started in the mid-1850s were the main drivers for the emissions. This has contributed to more frequent extreme weather events like rainstorms, heatwaves and hurricanes, posing major environmental and social damages such as loss of lives, assets, habitats and work hours, as a result of droughts, floods, sea level rise and ice sheets melting.
