Global Warming: Agricultures Role and Health Concerns
Because of global warming, temperatures obviously increase. This has some temporary benefits. For awhile, it will simply mean more time for crops to mature because of a longer growing season. This is especially true of regions where the spring and fall were once quite cool.
Higher temperatures can bring problems in other areas. In regions that are already warm, global warming will cause the plants to languish in the heat. Soil evaporation rates will be very high, leaving very dry earth. Add to that, droughts that will make both the soil and the air dry and might even lead to burning of some crops.
Right now, and in the near future, global warming does not seem to be a very dangerous situation for North American farmers. There might even be some positive effects. However, in the long run, nothing will be able to mitigate the damage that will be caused by global warming if it is not stopped.
Health concerns related to global warming
As global warming affects the environment, it should not be surprising that it affects the health of the people living in that environment. Changes in the climate are changes in the habitats not only for animals, but for people as well. Climate changes are already impacting people’s health.
There have also been heat waves in North America. One in 2006 claimed 226 lives. Another probable result of global warming is increased pollen in the air. This happens because higher levels of carbon dioxide encourage the growth of more pollen-producing weeds. Because more pollen means worse air quality, those with allergies and asthma suffer.
If all people knew how much global warming can affect their health, they might be more prone to working on a solution. Until then, those who understand the ramifications of global warming will have to work even harder.
