Some studies show that the news of global warming is not all bad for farming, at least not in the short run. While humans have changed many environmental factors by their activities, the short term effects of these changes often lead to better crops.

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.

There have always been many obstacles to farming. Global warming just makes them more intense. Now, it is even more likely that a farmer will face droughts, floods, heat waves, and hurricanes, to name a few. They will be harder to overcome than ever before and they will certainly be less rare.

Health concerns

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.

Curtailing global warming would lessen the incidence of flooding and prevent this many times. Since global warming can have an affect on the food supply, it is obvious that people can suffer from malnutrition because of this. This is especially true in agrarian societies in underdeveloped countries.
