Dear reader,
The aim of this magazine is to make you aware of
the problems which affect our world. If you´re looking
for something worth fighting, this magazine might give
you some ideas. There are too many things in risk. Our
home is in great danger and if we don’t start doing
something, it is very likely that the Earth won’t resist to
our abuses. Why do we keep doing this? We are
harming ourselves. After all it’s our species which will
become homeless.
So even if you don’t care with the environment,
care with you! Do you want to die due to pure
stupidity? You know what to do!
Get started!

Natural Resources
The water in rivers and streams can be captured and turned into
hydropower (or hydroelectric power). The common form of using
hydropower is cheap and it does not produce air pollution. The
problem is that damming rivers can change the ecology of the
region.
Another way to use water energy is by using the ways of the
ocean. This is a new and very exciting development for many
countries.
Water
Energy from the sun is used to warm and light our homes, heat our
water, and provide electricity to power our lights, cookers,
refrigerators and other appliances. This energy comes from a
process called solar heating.
Fire
For centuries, wind has been used to sail ships, grind grain, and pump
water. Now, people use the wind to generate electricity. Today’s
wind turbines usually have just two or three blades that turn when the
wind blows. The blades drive a generator that produces electricity.
Large groups of wind turbines, called wind farms or wind plants, are
connected to electric power lines and provide electricity to many
people. In Portugal, there are wind farms.
Wind
We can also get energy directly from the heat in the earth.
Geothermal energy comes from hot, melted rock (called magma)
which is in the earth’s surface. The heat warms underground pools.
Sometimes the water can even boil to produce steam.
For thousands of years, people have been using hot springs for
bathing and for cooking. Geothermal energy is also used to produce
electricity.
Earth
Trees protect people from ultra-
violet rays
Skin cancer is the most common form of cancer in the
United States. Trees reduce UV-B exposure by about 50
percent.
Trees conserve energy
Three trees placed strategically around a single-family
home can cut summer air conditioning needs by up to
50 percent. By reducing the energy demand for
cooling our houses, we reduce carbon dioxide
emission.
Trees provide oxygen
In one year an acre of mature trees can
provide enough oxygen for 18 people.
Every tree counts
´
Trees reduce violence
Neighborhoods and homes which are barren have
shown to have a greater incidence of violence in
and out of the home than their greener
counterparts. Trees and landscape help to reduce
the level of fear.
Trees are teachers and
playmates
Whether as houses for children or creative and
spiritual inspiration for adults, trees have provided
the space for human retreat throughout the ages.
Trees add unity
Trees as landmarks can give a neighborhood a
new identity and encourage civic pride.
Art and Nature
Scientists have been warning us about the problems of
global warming and other environmental issues for years.
However, the environment still hasn’t become the top priority
of many politicians around the world. As a result, a group of
people have decided to show their concern in quite a
different way.
The Artists for Conservation Foundation (AFC) has been
supporting environmental issues such as wild life and habitat
conservation since its foundation. The group which started
more than ten years ago, is a non-profit, international
organisation based in Vancouver, Canada. Over the years, it
has attracted a membership in about 500 of the world’s most
talented nature artists from thirty different countries.
Hundreds of pieces of artwork have been sold through its
website and the artists have already contributed with over
than $13 million to over 100 conservation organizations around
the world.
The pictures show the beauty of nature, but they show
the problems of climate change and the threat to
endangered species too. Through their art, the artists are
helping to communicate what scientist have been saying for
decades that we must stop harming nature if we want to keep
our planet.
Water management
1. Check faucets, pipes and
toilets for leaks.
2. Put bricks in your toilet tank.
This can save more than 10
gallons of water per day. Be
sure that at least 3 gallons of
water remain in the tank.
4. Take shorter showers. A 4
minutes shower uses
approximately 20 to 40
gallons of water.
3. Don’t leave the hose
running while you are
washing your car.
5. Do not use the toilet as an
ashtray or a wastebasket – Every
time you flush a cigarette butt,
facial tissue or other small bit of
trash, 5 to 7 gallons of water are
wasted.
6. Add a layer of mulch around
your trees and plants, this will
help slow the evaporation
process and you will need to
water them less.
7. Do not run the dishwasher or
washing-machine until the load
is full.
Climate Change
What are the effects of climate
change?
It is very important to predict exactly
what will happen as the Earth’s
temperature rise. However, scientists
believe that the glaciers will melt into
the ocean, causing sea levels to rise
drastically. Most people are terrified of
the terrible effects this could have on
the world we live in.
Higher sea levels could cause flooding
of coastal lands. Warmer ocean water
can increase storm activity on the
coasts, and areas away from the coasts
may experience droughts.
What causes climate change?
Scientists are not completely sure about the causes of climate change.
Most scientists interested in the subject believe that human activity is
speeding up climate change.
When sunlight enters the Earth’s
atmosphere, it passes through a layer of
greenhouse gases which are created
naturally. However, humans also create
them by burning fossil fuels. When they
are in excess, they cause the
temperature to rise.
Calamities
Floods and Droughts
The basic cause of all droughts is not enough rain. The land can
become starved of nourishment which makes it impossible to grow
anything.
Hurricanes, cyclones and
typhoons
Tropical storms are called
hurricanes over the North Atlantic
Ocean, cyclones over the Indian
Ocean and typhoons over the
north-west Pacific.
A hurricane is one of the most
powerful weather systems. Coastal
regions can also get hit by huge
waves. Plus there can be serious
floods in other areas because of
the rain that these storms bring.
Farmers are terrified of droughts because they
can be disastrous for their livelihood. Floods can
be just as bad, too.
Opinion
Who needs a house?
I don’t know about you, but I am so sick of hearing others saying
what has to be done about the environmental problems. They are
always saying the same things and we are supposed to do whatever
they say! And I’m not even sure there’s a problem.
Pollution and sea levels aren’t increasing dramatically and the
climate changes aren’t noticeable at all! Plus, the temperature isn’t
even rising!
Why do we need to care? If the earth is dying why does
everybody keep acting as if nothing is off? If there was something
wrong, I’m sure people would care! After all, Earth is our home and is
our duty to look after it... No! There’s nothing wrong! Mankind wouldn’t
be selfish to the point of putting future generations at risk just because
the wastepaper basket is too far away and it’s easier to leave the
rubbish on the floor or because the people who rule us are so greedy
they don´t even care if their country is making too much pollution.
No, everything is fine and if it’s not.... well, who needs a planet to
leave in? At least we saved ourselves from walking a meter to put the
rubbish in the trash!
