Depending on how balanced the climate conditions are, that can have severe impact on the production of food. Because of the uncertainties of the climate, cropland reductions vary from 10 to 50 percent. According to this article and the opinions of David Pimentel, global warming could alter the production of rice, wheat, corn, soybeans, and potatoes. This change will cause regional variations in North America because we are the main food grower. By 2030 it is predicted that atmospheric carbon dioxide concentrations will double pre-industrial concentrations while other greenhouse gases will increase substantially, and the temperatures in North America will rise two degrees. The farming industry will not do as well because agricultural production will be affected by both the severity and pace of climate change. If the change was slow and not as rapid, then crops wouldn't suffer as much as they would with such uncontrollable climate affects. Carbon dioxide as well as ultraviolet radiation play a major part in the livelihood of crops. Through the release of chlorofluorocarbons, it has depleted a good amount of the o-zone layer, making it easier for plants to catch various diseases. Also, with increased carbon dioxide levels, some plants do not benefit well from this while very few can.

According to the U.S Global Change Research Program, it stated that, “Climate change has had an impact on American farmers, ranchers, rural land owners, and foresters, and will continue to do so, through its influence on production, distribution, and yields.” Which leaves the reader wondering, so what? Well, if you truly care about living, these things are only here to help not hinder. CO2 levels are rising, why? Because of us and the different types of gases we let out into our atmosphere. The crops that are grown will eventually fail, because their existence relies on our choices.

According to this cite, before 2100 grain will have to double to 4 billion tons a year. Between now and mid-century, higher temperatures in northerly latitudes will probably expand lands that are available for farming. But even with these positive gains, they will most likely be canceled due to agricultural declines in the tropics. Higher temperatures can also cause outbreaks of weeds and pests as well as affect the way a plant looks. Because of temperature differences, pests that are very active during the winter are expected to improve making them able to attack the spring crops and once again causing major food shortage.
Incorporating this information into my senior project:
I plan to speak about the effects climate change has on food and ways we can help this epidemic from spreading further.
I enjoyed reading your annotated sources...they are very informative! You picked great articles and I think they will help you a lot.
ReplyDeleteSo, your documentary will be on the future of food...how far will you take this? Will your film be very dramatic, in the sense that you give a senario where the food in the world is very limited? I think now you just need to read a few more articles to really round out your argument.

I think you need to go in depth with a few of your quotes, like what would happen if if the plants had to move, or what plants would be affected by global warming. I like your facts i think you just need to elaborate on some of the facts.
ReplyDeleteI like your blog and the topic your going for. You have pretty good sources, to get more info try look at source like NatGeo. and the BBC because they got some pretty good stuff. Maybe you should add some more quotes next time, I feel that you have a good project to get through many people.
ReplyDeleteVery nice, I like how you have some good resources. All you have to do is pull out more specifics about the information you discussed. I also think that you should discuss what would happen to the human population from the food issues.
ReplyDeleteI really liked what you talk about because i thing is a really good issue that we all should be taking care of it. I think that you should also put more that how would humans be affected in the next 10 years if all the food was gone.
ReplyDeleteI enjoyed how you wrote this reflection and i understood everything you were talking about within this text. you can possibly go more into depth with talking about how -..."If the change was slow and not as rapid, then crops wouldn't suffer as much as they would with such uncontrollable climate affects." because if you went more into depth with this issue i think people would open there eyes and realize the issue that is being informed by your reflection.
ReplyDeleteQuestions:
How will the crops not suffer as much? I think you should go more into depth and explain this sentence a little more so that not only i but our other peers will understand this better.
i think you have some really good information and that you seem to know what connections climate change has in your topic. i think you have some really good articles that are going to help you with your senior project =)
ReplyDeleteYou have a lot of good information. I'm interested to know if what you said about the plants being able to survive a gradual temperature change is fact or just opinion it seems like it could be either. I'm excited to see how you connect all this information and put it in your video.
