4. Food
Consumption of Food
The average person eats about 35 tons of food during a
lifetime. That’s equal to 1500 pounds or 680.4 kilograms a
year.
The exact amount of food an individual person eats in a
lifetime varies based on the person's gender, size, diet and
lifespan.
5. Food
Wastage of Food
Roughly one third of the food produced in the world for
human consumption every year — approximately 1.3 billion
tones — gets lost or wasted.
Every year, consumers in rich countries waste almost as
much food (222 million tones) as the entire net food
production of sub-Saharan Africa (230 million tones)
6. Water
Availability ofWater on Earth
About 71 percent of the Earth's surface is water-covered, and
the oceans hold about 96.5 percent of all Earth's water. But
water also exists in the air as water vapor, in rivers and lakes,
in icecaps and glaciers, in the ground as soil moisture and
in aquifers.
Nearly 70% of that fresh water is frozen in the icecaps
of Antarctica and Greenland; most of the remainder is
present as soil moisture, or lies in deep underground aquifers
as groundwater not accessible to human use.
7. Water
Consumption ofWater
97.5% of all water on Earth is salt water, leaving only 2.5% as
fresh water.
Only 1% of the world's fresh water is accessible for direct
human uses.This is the water found in lakes, rivers, and
those underground sources. Only this amount is regularly
renewed by rain and snowfall, and is therefore available on a
sustainable basis.
8. Water
Wastage ofWater
About 23 million liters of water are wasted everyday on
earth! An average person uses about 123 gallons (466
liters) of water daily
9. Wild Nature
TotalTigers inWorld
At the start of the 20th century, it is estimated there were
over 100,000 tigers in the wild.
Hunting for fur and body parts but the population has
dwindled outside of captivity to between 3,062and 3,948.
10. Wild Nature
How ManyTigers are Left
A century ago there were 100,000 tigers roaming the
forests, swamps, and tundra ofAsia.TODAY, there are as
few as 3,200 left in the wild. Only 7% of historic tiger
habitat still contains tigers.
At this rate, wild tigers will be extinct in just a few
decades.
11. Energy
Energy Resources
Primary energy sources take many forms, including nuclear
energy, fossil energy ( like oil, coal and natural gas) and
renewable sources like wind, solar, hydropower.
These primary sources are converted to electricity, a
secondary energy source, which flows through power lines
and other transmission infrastructure to your home and
business
12. Energy
Production of Electricity
Electricity - production: 22.03 trillion kWh (2011).
EIA estimates that about 21% of world electricity
generation was from renewable energy in 2011,2 with a
projection for nearly 25% in 2040.
13. Energy
Consumption of Electricity
Electricity - consumption: 20.45 trillion kWh (2010).
The U.S. Energy InformationAdministration (EIA)
estimates that about 11% of world marketed energy
consumption is from renewable energy sources
(biofuel, biomass, geothermal, hydropower, solar,
and wind)with a projection for 15% by 2040.
