What are main environmental problems?
Main environmental problems are:
Air pollution – Greenhouse effect
The atmosphere is polluted by exhaust fumes of
cars and factories.
Cars are the biggest polluters - they are main
cause of bad air quality.
Gases like carbon dioxide and methane are called
„the greenhouse gases“.
These gases trap the heat in atmosphere.
This is known as the greenhouse effect.
Greenhouse effect - Global warming
Greenhouse effect can bring the global warming.
Global warming is the increasing of the
temperature of Earth.
If the air gets too hot, the balance of life on Earth
will be disrupted.
Scientists think that this can be dangerous for all
There are many organizations trying to protect our
environment, for example:
Friends of the Earth
World Wildlife Fund
What can you do to protect the
If we want to protect the atmosphere we
should use public transport more often because it
is better for environment than cars.
Going by bus helps reduce pollution.
And it is better to walk or cycle whenever we
can; it is very healthy and helps ecology.
What can you do to protect the environment?
We shouldn´t be noisy in the woods, not pick
We should never light fire in forests - trees will
We shouldn´t use fertilizers in the garden
We shouldn´t buy pre-packed food –
there is a lot of waste from it
We should use less washing up liquid -
it pollutes the seas and rivers
We shouldn´t drop rubbish in the street
- it looks and smells horrible
What can you say about the problem of
People are producing more and more waste.
This waste can pollute the ground, water and
What can we do to help? We should remember
the three Rs:
Reduce! – Reuse! – Recycle!
Reduce! – Reuse! – Recycle!
Don´t buy things you don´t really need. By
reusing things and materials we can cut down on
the amount of waste
Plastic bottles or bags or whatever can be reused.
Give old things you don´t need (such as clothes, toys,
CDs) to charity. Share books, magazines, newspapers.
Recycling has a very important role in reducing
pollution and protecting natural resources.
Separating of waste for recycling is very important.
Sort out waste and put it into containers.
Things for recycling:
Paper - a lot of paper products can be made from
recycled paper – newspapers, toilet paper, egg
Printer ink cartridges
What should be done to prevent wasting of
energy in households?
Every year people need more and more energy.
To prevent wasting of energy:
We should turn the heating down and dress
warmer if we're cold
We should save energy - switch off lights and
other electrical appliances (TV, PC) when we're
not using them
We should use energy-efficient products
We should use rechargeable batteries
We should save water (have a shower rather
than a bath)
We can see that each of us could change
our lifestyle to protect our planet.
