roughly 1/3 of the world’s food is never eaten

Question 2

in low income areas, how does waste come about

Answer 2

generally unintentional and occurs on farms or during storage or distributionh

Question 3

how can we combat food waste in low income areas

Answer 3

improve infrastructure for storage, processinf, and transportation

Question 4

in high income areas how does food waste come about

Answer 4

over serving
food thrown away due to quality standards

Question 5

how do we prevent food waste in high income areas

Answer 5

major interventions required at the retail and consumer level

Question 6

food we waste is responsible for what percent of global emissions

Answer 6

8%

Question 7

how would plant rich diets reduce emissions

Answer 7

reduces demand on animal agriculture, reduces land clearing, fertilizer use, and ghg from these activtiies

Question 8

how do refrigerants affect the atmosphere

Answer 8

fluorinated gasses are used as refrigerants and they have a potent ghg effect
managing leaks and disposal of these chemicals can avoid emissions in buildings and landfills

Question 9

what are pros of using wind turbines

Answer 9

is competitive with or less expensive than coal-generated electricity
have small footprints (no more than 1%)
takes one year or less to build a wind farm

Question 10

how can we reduce emissions from refrigerants

Answer 10

1. lower demand for applicanes
   2.replace refrigerants with substaanecs with lower global warming impacts
2. increase refrigeration efficiency of appliances to control leakage
3. recover, reclaim, recycle, and destroy refrigereants

Question 11

how can solar photovoltaics help to reduce emissions

Answer 11

they can be used at utility scale with hundreds or thousands of solar panels to replace the fossil fuel electricity generation

Question 12

how much of global electricity generation is estimated to be from utility scale solar photovoltaics

Answer 12

just over 3%

Question 13

how can clean cooking reduce emissions

Answer 13

can reduce pollution from burning wood or coal in traditional stoves and protect human health

Question 14

An estimated ___ of families in low-and middle income countries were mainly using cookstoves fueled by traditional woord or coal stoves for cooking

Answer 14

43%

Question 15

Improvement in air quality due to removal of solid fuel cookstoves could avoid _____premature deaths globally between 2000 and 2050

Answer 15

10.5 million

Question 16

recent scenarios have predicted that almost ____ of global electricity could come from solar PV by 2050.

Answer 16

60 percent

Question 17

silvopasture

Answer 17

Integrates trees, pasture, and forage into a single system

Question 18

why is silvopasture helpful for the environment

Answer 18

Incorporating trees into agriculture improves land health and increases carbon sequestration
Pastures with trees sequester five to 10 times as much carbon as those of the same size that are treeless while maintaining or increasing productivity and providing a suite of additional benefits.

Question 19

perennial staple crops

Answer 19

Provide important foods, such as bananas, avocados, and breadfruit
Production of trees and other perennial crops for staple protein, fats, and starch
These perennial staple crops yield as well or better than their annual staple crop competitors
They also sequester impressive carbon in soils and above-ground biomass
Thrive under many different conditions that annual crops can’t

Question 20

multistrata agroforestry

Answer 20

Mimic the structure of natural forests
Layered trees and crops achieve high rates of both carbon sequestration and food production
One or more layers of crops grow in the shade of taller trees
