Greenhouse effect- is the trapping of solar heat by I.
Ozone layer – is depleted by C and increases the amount of E
reaching earth which affects F and L.

increased by human activities.
M development is when resources are used without depleting
them
Soil Erosion-wearing away of soil, caused by B.
Acid rain- smog and other pollutants lower pH of rain water
which affects G and F.
Biodiversity is biological diversity and is threatened by human
activities like B and H.
J occurs when a species disappears but species are considered K
when it’s population is declining.
Biological Magnification occurs when toxins like mercury are
