3. What is an environmental disaster
 “An environmental disaster is a disaster that is due to human
activity and should not be confused with natural disasters. In
this case, the impact of human alteration of the ecosystem
has led to widespread and long-lasting consequences. It can
include the deaths of animals (including humans) and plant
systems, or severe disrupt of human life, possibly requiring
migration.”

9. Their impact – on Earth/People
 Houses, buildings, and other structures can be destroyed;
 Loss of power;
 Fire;
 Loss of habitat;
 Contaminated water;
 Toxic gases released into the atmosphere;
 Carbon dioxide emitted from volcanoes adds to the natural
greenhouse effect;
 Trees fall;
 Diseases;

10.  Tornadoes can hit hazardous or toxic materials which can carry
by a thunderstorm and then be transported along ways down
stream;
 Destroy topsoil and crops;
 Dried up lakes and other water sources;
 People use more fuel during droughts;
 Lack of food and drinking water for wild animals;
 Increased stress on endangered species;
 Wind and water erosion of soils, reduced soil quality;

12. Small changes to help save the
planet
 Recycle;
 Reduce the use of fossil fuels;
 Pay attention how we use the water;
 Try not to use your car so much. Instead, use
public transport;
 Use fluorescent light bulbs;
 Use as many natural light as you can;
 Don’t let the electronic devices in stand-by;
 Use rechargeable batteries;
 Try to use your email instead of paper;

13. Conclusion
 With this project work we learned that there is many
environmental disasters and the most part of the natural disasters
have a small help from mankind.
 The environmental disasters are very dangerous and can put in
risk thousands of lives (humans and animals) and a lot of species
loses their habitat which can cause the extinction of many
species.
 We also learned that with small changes at our homes and in our
daily lives we can make the difference and help save the planet.
