Global Warming By: Danielle Hughes, Margaret Spell, Michael Phuster, Daniel Gonzalez
What is global warming? Global warming is the increase in temperature on a global scale The temperature has increased 1°F over 100 years Global warming causes... –Rise in sea level –Extinction of animals unable to adapt –Etc. The biggest contributor, which we researched, are because of agriculture
Agriculture Agriculture includes both livestock and crops Examples of agriculture are… –Cow –Corn –Sheep All are domesticated for human use
How does agriculture affect global warming? Both livestock and crops effect global warming negatively The livestock’s waste and flatulence are harmful to the environment because methane is a greenhouse gas With over 1 billion cows, that’s a lot of methane!
How does agriculture affect global warming? (continued) Crops affect global warming as well Rice that is cultivated releases methane when harvested We harvest large amounts of rice because it is an important crop –This makes a large effect on global warming
Some Facts Processes of crops produces most methane, carbon dioxide, nitrous oxide that effect global warming All the livestock in world produce 35%-40% of the methane because of waste and flatulence Livestock production occupies 30% of the Earth’s surface
