There has been a significant climatic change that has taken placethroughout the years on Earth.
These changes have effected society in more thanone way. However, there is nothing society can do about the long term influencesof climatic changes. Society has tended to address the short term effects ofclimatic changes that influence the global temperatures within the life span ofpresent generations. The following will show how climatic changes does effectsociety, health, and economics.Society depends a lot on natural resources for various aspects. First ofall, society depends largely on forests to supply trees which in turn supplywood for construction. Other resources include oil and animals (livestock). Inthe focus of wood, there is the Western Canadian Boreal Forest which is a largeproducer of wood for the United States construction industry.
However, climaticchanges has had large and impacting effects on the construction industry.Compared to eastern Canada, the southern boreal forest region of western Canadahas a relatively dry climate. Thus, drought effects are one of the majorconcerns being addressed by researchers in this region. climate modellers havepredicted a large increase in temperature for this region, which could lead toeven drier conditions and enormous stresses on vegetation in the westernCanadian boreal forest. This type of impact was observed following the 1988drought it experiences, when there was a die-back of aspen over extensive areasof the aspen parkland in Western Canada. Associated with this drought was adrying up of large lakes in the region. Another potential impact for the regionis a major increase in forest fires. This is due to the fact that fire frequencyis closely linked to moisture levels which are expected to decrease underclimatic change.
Thus, it is noticed that with increased climatic change thefuture that this forest has in supplying lumber is decreasing, and theconstruction industry will face a slight drawback due to this. In this it isnoticed that, with a drawback in the construction industry’s output, will alsoeffect the economy and society. The economy will effect society and the decreasein output means a decrease in jobs, which in effect hurts society.Contrary to the example of the forests in Canada, is the informationfound on its agriculture. Because average temperatures are expected to increasemore near the poles than near the equator, the shift in climatic zones will bemore pronounced in the higher latitudes. In the mid-latitude regions ( 45 – 60latitude ), the shift is expected to be about 200-300 kilometers for everydegree Celsius of warming.
Since today’s latitudinal climate belts are eachoptimal for particular crops, such shifts could have a powerful impact onagricultural and livestock production. For example, in the Canadian prairies,the growing season might lengthen by 10 days for every 1oC increase in averageannual temperature.Another example (Taken from sources on the net) is the impact of climatechange on water. Now, water is a survival of mankind, in general, but almost forall life. Thus, if water was effected by climatic changes, so would society,health, as well as economics be impacted by climatic changes. In areas whereclimate change causes reduced precipitation, freshwater storage reserves,primarily in the form of groundwater, will steadily shrink.
Areas where moreprecipitation was not matched by increased evaporation would experience floodsand higher lake and river levels. An increase in extreme events such as droughtsand floods would undermine the reliability of many critical sources. Diminishedsnow accumulation in winter would reduce the spring run-off that can be vital toreplenishing lakes and rivers; a 10% decline in precipitation and a 1-2oC risein temperature could reduce run-off by 40-70% in drier basins. Worseningdroughts combined with the over-exploitation of water resources would cause saltto leach from the soil, thus raising the salinity of the unsaturated zone (thelayer between the ground and the underlying water table). In coastal zones, alowered water table would also draw salt-water from the sea in the freshgroundwater. At the same time, higher levels of carbon dioxide in the atmosphereare expected to improve the efficiency of photosynthesis in plants, which couldin turn cause more rapid evapo-transpiration. Together, these various effectswould have extremely negative consequences for river watersheds, lake levels,aquifers, and other sources of freshwater. As it is seen in the informationfound, such consequences would in reality effect society, agriculture, andeconomics.
Society, would have lower levels of freshwater, agriculture wouldalso have lower levels of freshwater to survive on. Because of this, the economywould be effected since more work will need to be enforced to revitalize thesources of freshwater, or find more.It can be seen through these previous examples, that society is effectedby various forms of climatic change. Thus, if society is effected, so is thehealth of people within the society, and economics is also effected.
Itbasically is like a continual cycle that persists with a relation betweenclimatic changes and the effects it has on society, health, and economics.Category: Social Issues
