TRAGEDY OF THE COMMONS
PEOPLE WILL ALWAYS OPT FOR THE
IMMEDIATE BENEFIT
WE WILL ALWAYS ADD ONE TOO MANY
SHEEP TO THE FIELD, DESTROYING THE
COMMONS
SAND COUNTY ALMANAC
ALDO LEOPOLD
LAND ETHICS
FIRST LAW OF THERMODYNAMICS
CHEMICAL ENERGY --> MECHANICAL
ENERGY --> HEAT
ENERGY CANNOT BE CREATED OR
DESTROYED, ONLY CONVERTED FROM
ONE FORM TO ANOTHER
CARBON
MAIN COMPONENT IN ORGANIC COMPOUNDS
COMBINES WITH OXYGEN TO FORM CO2
LARGEST SINK IN OCEANS
CORAL REEFS
HOW HUMANS INTERFERE IN THE
NITROGEN CYCLE
BURNING FOSSIL FUELS
DESTROYING FORESTS, GRASSLANDS,
WETLANDS
AGRICULTURE- ADDS NITROGEN TO
AQUATIC SYSTEMS AND RELEASES NOX

INTERNATIONAL TRADE/SALE OF
THREATENED/ENDANGERED SPECIES
NITROGEN FIXATION
BACTERIA IN SOIL AND BLUE-GREEN
ALGAE COMBINE GASEOUS N2 WITH
HYDROGEN TO MAKE NH3
BACTERIA USE SOME OF AMMONIA FOR
NUTRITION AND EXCRETE THE REST TO
THE SOIL WHICH IS THEN CONVERTED
INTO NH4+ THAT IS USED BY PLANTS
NITRIFICATION
AMMONIA NOT TAKEN UP BY PLANTS IS
CONVERTED TO NITRATE IONS BY
BACTERIA
AMMONIFICATION
SPECIALIZED BACTERIA CONVERT DEAD
MATERIAL AND WASTE INTO NH3 AND
NH4+
DENITRIFICATION
BACTERIA IN WET ENVIRONMENTS
CONVERT THE NH3 AND NH4 BACK INTO
NO3+ AND NO2+ ION, AND THEN BACK
INTO N2 AND N2O
THE LAST STEP IN THE NITROGEN CYCLE
AND THEN IT REPEATS!
