The topic of my presentation is «Ecological problems in the world».
I’ve divided my presentation into three parts. Today's topic is of particular interest to those of you who want to know the causes of environmental pollution.
I will tell you about the 3 main   by humanity.
On the first slide you can see water pollution. It is the contamination of water sources by substances which make the water unusable for drinking, cooking, cleaning, swimming, and other activities. Pollutants include chemicals, trash, bacteria, and parasites. All forms of pollution eventually make their way to water.
 	The next slide shows air pollution. It is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution.
	On the last slide present ozone layer. The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents, CFCs.
That’s all I wanted to say about ecological problems in the world. 
Thanks for your attention. Any questions?
