1.The difference in average global temperature between today and the last ice-age, 10,000 years ago, is only about 5oC. So why should we be concerned about the documented 0.8oC degree change instigated by humans?
2.What is the biological interaction between birds and insects like the pear thrip and the forest tent caterpillar? How will climate change leave their habitats vulnerable?
3.What is your largest source of emissions (prior to COVID 19)?
4.What steps can you take to decrease your carbon emissions (after COVID 19)?
5.Interpreting data: A 2010 study compared the amount of CO2 emitted when a locally grown broccoli was delivered to Virginia Tech University vs. the amount of CO2 emitted when broccoli from California was delivered there. The Californian broccoli was delivered in shipments containing 768 lbs of broccoli, in a trailer that traveled 2,786 miles. Trailer fuel efficiency is 5 miles per gallon, and 20 lbs of CO2 are released per gallon of fuel burned. The local broccoli was delivered in shipments of 587 lbs of broccoli in a van that traveled 19.1 miles. Van fuel efficiency is 16 miles per gallon, and 20 lbs of CO2 are released per gallon of fuel burned.
6.Complete the following table to determine the CO2 emissions associated with delivering 1 lb of non local broccoli. Show work below table!
Source of Broccoli
Miles per shipment
Gallons of Fuel burned per shipment
CO2 Released per shipment (lbs)
CO2 Released per lb of broccoli delivered
