Developing countries, specifically those dependent on commodities, are particularly vulnerable to climate change, but also, the commodities they produce affect the climate. On the one hand, extreme weather patterns such as heatwaves, floods, hurricanes and frequent seasonal abnormalities have been adversely affecting crop yields and fish production, and destroying infrastructure in the mining sector. On the other hand, clearance of forests for agricultural expansion, including rearing of livestock, and for mining and drilling projects for the extraction and use of fossil fuels, are the greatest sources of greenhouse gas (GHG) emissions that are largely responsible for climate change.
