Are Humans Responsible For Climate Change Essay

Are Humans Responsible For Climate Change? Climate change and global warming have always been an issue, but in recent years, the global temperature has increased significantly. The main cause of climate change is the expansion of greenhouse gases in the atmosphere, which are omitted by humans. Due to humans clearing land for agriculture and factories, this has increased the concentration of carbon dioxide in earth’s atmosphere. The large amount of greenhouse gases in earth’s atmosphere, cause for heat to be trapped in the atmosphere more easily, which eventually leads to sea level rise, more evaporation, less precipitation, and overall, warmer weather conditions. Some regions will become dryer, due to less precipitation,

If it were not for the amount of greenhouse gas in the atmosphere, sea ice and glaciers would not continue to melt, therefore some of the world’s most interesting species would not be in danger. Carbon dioxide is a minor but vital element that is needed for the earth to thrive. We humans intake oxygen and exhale carbon dioxide, from there on, trees and plants absorb that excess carbon dioxide. Trees continue to absorb excess CO2, however, agriculture and deforestation have caused for an even higher increase of carbon dioxide. Since there are less trees on the earth’s surface, the excess carbon dioxide that we as humans let off, is unable to be absorbed.

Most crops need the right balance of precipitation, sunlight, and heat, as some crops are delicate and won’t grow, unless under the right conditions. However some crops and plants have reacted in a positive way to increased atmospheric CO2, as they grow more vigorously and use water more efficiently. Meanwhile, higher temperatures and shifting climate patterns may change the areas where crops grow best and affect the makeup of natural plant communities. Some crops thrive better and more efficiently in warmer climates such as citrus fruit. Citrus does not
