Climate Change And World Food Supply Essay

, Research Paper


The world needs to think of how the


climate is changing the food supply of the


earth. The climate is doing some really


bad things to the earth. The atmosphere is


also not in good shape because of climate


change. Humans now need to think of


how climate change is affecting people.


Climate change is affecting the food


supply of the world.


The climate change is rapidly affecting the


earth. The Greenhouse gases are what is


really messing up are world food supply


and what is messing up our earth. Global


Warming is causing concerns because of


its high content in the atmosphere already.


Because of global warming the earth is


going down hill fast. We the people need


to step up and take part in the fight


against greenhouse gases. Greenhouse


gases are what are leading to climate


change, and climate change is what is


leading to the depletion of the world food


supply. Because of rising greenhouse


gases, by the year 2060 the temperature


will rise 12 degrees (Pittock 1). We have


to use more fertilizer instead of chemical


fertilizers. Natural fertilizers aren?t


harmful to the environment.


Scientists think that if we are lucky the


populations will only double in the next 66


years (Roach 3). Although we will still


have to increase the


Wicker Page 3


demand for food. Between 1989 and


1990 the crops increased by 60 percent


(Pittock 4). Between these two years we


have increased farm machinery by 4.7


times what it was before (Pittock 4). And


we gave increased electricity by 5.1 times


what it was before (Pittock 4).


The climate change is affecting our


atmosphere and a lot of people don?t


know that. There are lots of pollutants in


the atmosphere but the two that are


important in global warming and climate


change are carbon dioxide and CFCs.


Between those two, carbon dioxide ranks


number one pollutant in the atmosphere.


CFC?s are bad too, but not nearly as bad


as carbon dioxide. CFC?s quicken global


warming (Weier 1). Greenhouse gases


consist of carbon dioxide mainly and that


is why we need to get rid of greenhouse


gases all together.


Believe it or not climate change affects


people too. Global warming and pollution

affects peoples breathing. Lately people


with asthma have had a hard tine


breathing because of global warming and


pollution. Doctors have had more asthma


patients in this year then in any year


(Weier 2). So now what do you people


think of global warming and pollution?


The green revolution was largely based on


increased energy in the form of irrigation,


mechanization, fertilizers, and pesticides.

So far the production yields in crops are


negative in the low latitude countries


because of climate change. Natural


fertilizer helps crops by 22 percent where


as chemical fertilizers help a little better


than that but they are harmful to the soil.


Climate change can affect rainfall


intensity, weather extremes, pests, and


diseases. Studies have shown that Sub


Saharan Africa will get the worst of global


climate change and pollution. Also studies


show that food production will have to


grow 2 percent every year to sustain the


food supply (Roach 1). Scientists state


that this is possible.


The world food supply is changing and


the population needs to think about how


to stop this from happening. Changing


climate is changing our earth. As the


climate is changing so is the world food


supply. There is a high content of


greenhouse gases in the atmosphere.


People need to use natural fertilizers


instead of chemical fertilizers. We need to


increase the demand for food. Climate


change affects people too. The Green


Revolution was based on the mechanics


of farming. Climate change affects


weather patterns too. Food production


must increase 2 percent ever year to keep


up with the population of the world.
