Part2: Problem analysis: Agriculture: “While CO2 is essential for plant growth‚ all agriculture depends also on steady water supplies‚ and climate change is likely to disrupt those supplies through floods and droughts. It has been suggested that higher latitudes—Siberia‚ for example—may become productive due to global warming‚ but the soil in Arctic and bordering territories is very poor‚ and the amount of sunlight reaching the ground in summer will not change because it is governed by the tilt of

My Carbon Footprint – Homework 9 According to the results of the carbon footprint calculator‚ I contribute to the greenhouse gas emissions. My behavior breakdown pie chart illustrates that my home energy contributes 44.8%‚ my driving and flying contributes 39.4%‚ my recycling and waste contribute 2.2%‚ and my food and diet contribute 13.6% to the greenhouse gas emissions causing climate change and other environmental problems. My estimated greenhouse gas emissions are 43 tons of carbon dioxide
