Word Count: 662The world needs to think of how theclimate is changing the food supply of theearth. The climate is doing some reallybad things to the earth. The atmosphere isalso not in good shape because of climatechange. Humans now need to think ofhow climate change is affecting people. Climate change is affecting the foodsupply of the world.
The climate change is rapidly affecting theearth. The Greenhouse gases are what isreally messing up are world food supplyand what is messing up our earth. GlobalWarming is causing concerns because ofits high content in the atmosphere already. Because of global warming the earth isgoing down hill fast.
We the people needto step up and take part in the fightagainst greenhouse gases. Greenhousegases are what are leading to climatechange, and climate change is what isleading to the depletion of the world foodsupply. Because of rising greenhousegases, by the year 2060 the temperaturewill rise 12 degrees (Pittock 1). We haveto use more fertilizer instead of chemicalfertilizers. Natural fertilizers arentharmful to the environment. Scientists think that if we are lucky thepopulations will only double in the next 66years (Roach 3).Order now
Although we will stillhave to increase the Wicker Page 3demand for food. Between 1989 and1990 the crops increased by 60 percent(Pittock 4). Between these two years wehave increased farm machinery by 4. 7times what it was before (Pittock 4). Andwe gave increased electricity by 5. 1 timeswhat it was before (Pittock 4).
The climate change is affecting ouratmosphere and a lot of people dontknow that. There are lots of pollutants inthe atmosphere but the two that areimportant in global warming and climatechange are carbon dioxide and CFCs. Between those two, carbon dioxide ranksnumber one pollutant in the atmosphere. CFCs are bad too, but not nearly as badas carbon dioxide.
CFCs quicken globalwarming (Weier 1). Greenhouse gasesconsist of carbon dioxide mainly and thatis why we need to get rid of greenhousegases all together. Believe it or not climate change affectspeople too. Global warming and pollutionaffects peoples breathing.
Lately peoplewith asthma have had a hard tinebreathing because of global warming andpollution. Doctors have had more asthmapatients in this year then in any year(Weier 2). So now what do you peoplethink of global warming and pollution? The green revolution was largely based onincreased energy in the form of irrigation,mechanization, fertilizers, and pesticides. Wicker Page 4So far the production yields in crops arenegative in the low latitude countriesbecause of climate change. Naturalfertilizer helps crops by 22 percent whereas chemical fertilizers help a little betterthan that but they are harmful to the soil.
Climate change can affect rainfallintensity, weather extremes, pests, anddiseases. Studies have shown that SubSaharan Africa will get the worst of globalclimate change and pollution. Also studiesshow that food production will have togrow 2 percent every year to sustain thefood supply (Roach 1). Scientists statethat this is possible. The world food supply is changing andthe population needs to think about howto stop this from happening.
Changingclimate is changing our earth. As theclimate is changing so is the world foodsupply. There is a high content ofgreenhouse gases in the atmosphere. People need to use natural fertilizersinstead of chemical fertilizers. We need toincrease the demand for food.
Climatechange affects people too. The GreenRevolution was based on the mechanicsof farming. Climate change affectsweather patterns too. Food productionmust increase 2 percent ever year to keepup with the population of the world.
