Transcript of Carbon Footprint

Footprint
What is a
CARBON
FOOTPRINT?
A carbon footprint is a representation of the amount of carbon dioxide and other carbon compounds emitted from the combustion of fossil fuels by a particular person, group, organization, ect. from human activities.

What is happening?
Carbon Dioxide levels in the atmosphere are rapidly rising!
Why is this happening?
Scientists believe that humans could be responsible for the increasing carbon dioxide levels in the atmosphere
Human activities such as industry, the burning of rainforests, and transportation vehicles (especially cars) largely contribute to rising carbon dioxide levels
The Earth is heating up
The Greenhouse Effect
Humans produce green house gases through the combustion of fossil fuels
Carbon dioxide is the most significant greenhouse gas
anthropogenically
produced (produced by humans)
As more greenhouse gases are released, more
thermal energy is trapped
in the atmosphere which
raises global temperatures
However, increases in global temperature can cause increases in carbon dioxide levels. This is known as the

anthropogenic greenhouse effect
Anthropogenic Greenhouse Effect
Environmental Impact
* carbon sinks: carbon dioxide stored in plants and oceans
Social Impact
Green house gases have a direct effect on the environment, causing extreme weather changes, a global temperature increase, the loss of ecosystems and potentially hazardous health effects for people
Global Temperature Increase & Extreme Weather Changes

Green house gases allow sunlight to enter the atmosphere. As sunlight hits the Earth, some is re-radiated off the Earth's surface and back towards space. Some of this heat is
absorbed
by greenhouse gases and
trapped
in our atmosphere

Reportedly, the Earth's climate has increased between
0.6
and
0.9
degrees over the past century. This increase is attributed to human activity.

As greenhouse gases rise, the average temperature increases over time. The Earth's rising temperature produces a change in weather patterns and sea levels.
The Loss of Ecosystems
Rapid climate change, caused by our carbon footprints, affects the ability for ecosystems and animal species to
adapt
to
new climates
. This makes it difficult for any ecosystem to survive which is why our
biodiversity loss
is increasing.

The rapid climate change and accelerating biodiversity loss could be potentially hazardous to our health. A major food chain or even water sources, could decrease or even disappear. Without these essential resources there is a good chance that we could encounter serious health problems.

Ways to Reduce Your Carbon Footprint
Animals such as cows and sheep produce
methane
, which, after a time period of 20 years is
72
times more harmful than carbon dioxide. Eating more meats such as chicken and pork instead of red meats can be far more beneficial for the environment.

Eat Less Red Meat
Avoid Driving Your Car
The world is running out of oil and cars are one of the largest reasons why.  If more people were to walk, take their bike, carpool, or use public transportation to get to work or school, there would be less carbon dioxide emissions in the atmosphere
Water and energy are used to produce goods.  
Reduce
the amount of things you buy and the trash you create.
Re-use
the items you would normally throw in the garbage by making them into something else. (For example, old t-shirts can be made into couch cushions.)
Recycle
your plastics, metals and papers.  By doing these three things, less water and energy is wasted creating new products
Buy Local Produce
On average, food travels
1,500
miles from the farm to the supermarket. Buying food that is in season and
grown locally
can cut down the carbon dioxide emissions from transport vehicles drastically. 

Plant a Tree
A
10
year old tree can release enough oxygen to support
2 people
.

Trees provide shade and oxygen, as well as
take in
carbon dioxide. 
A young tree can take in
13
pounds of carbon dioxide yearly. 
An older tree can take in up to
48
pounds of carbon dioxide yearly. 
Buy A Laptop Instead of a Desktop
Laptops
are made to be
80%
more energy-efficient than desktops. 
Laptops have
energy-efficient
LCD screens, hard drives, CPU’s, and adapters that make them more friendly to the environment than desktops.
With the extreme climate changes and increased emissions of carbon dioxide, the effort to be more environmentally friendly has become a global concern.
The 2 largest contributors to our carbon footprints would probably be our
travel
and
electricity
needs
Carbon footprints are measured in units of carbon dioxide
In order to reduce the impact of our carbon footprint we need to learn how to calculate it
The simplest way to calculate a carbon footprint is through tracking your activities on an online calculator
Economic Impact
If climate change proceeds without any efforts to reduce it, we can expect to serious economic costs

These costs would go towards
adaptation
to new climates and
restoring
disturbed ecosystems
We can try to limit these costs by
reducing our emissions
and using more
renewable resources
