Main environmental problems are:
Air pollution – Greenhouse effect
The atmosphere is polluted by exhaust fumes of

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 of
There are many organizations trying to protect our

Friends of the Earth
World Wildlife Fund

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
We can see that each of us could change
our lifestyle to protect our planet.
