what are the 3 GHGs

Answer 1

carbon dioxide
methane
water vapour

Question 2

what is carbon footprint

Answer 2

total amount of co2 and other ghgs emitted over the full life cycle of a product

Question 3

how id carbon footprint reduced

Answer 3

.using processes that use less energy
.using renewable energy sources
.technology capturing co2 before released
taxing companies about GHGs release

Question 4

list some human actives that produce co2

Answer 4

land field sites
burning fossil fuels
agriculture(cows)
deforestation(less co2 taken in)

Question 5

what causes human activies to produce GHGs

Answer 5

cow=methane
land fields=release co2 + methane
deforestation=less co2 taken in
human activity is causing climate change due to scientists

Question 6

causes of rising co2 levels

Answer 6

extra heat=earths surface
transport(driving)
consuming electricity

Question 7

causes of rising methane levels

Answer 7

raising livestock
decay of organic waste (land fields)
agriculture

Question 8

climate change consequences and why

Answer 8

ice caps melting-higher sea levels
food production-cahnge in temp/rainfall
increasing ave temp
storms become more frequent
