Chemical Substance and Local Chemical Recycling
POLLUTION
Assalamualaikum and very good morning to my beloved lecturer ,Madam Asmad and my fellow friends. How are you today? Have you take your breakfast? I hope all of you in pink. Before I start my speech today. I want to tell to all of you that the reading level of air pollution today really worried today than 20 years before.
Today I will share with all of you about pollution. We could say that pollution is the harm that results because of the presence of a substance or substances where they would not normally be found or because they are present in larger than normal quantities. Polluting substances may occur as a solid, liquid or gas. The pollution could be water, air, sound any many more. So today I will tell about water pollution. In my speech I will divide the session to three section. First, the causes of this pollution, second the effects of this pollution and last how to overcome this problem. Firstly the causes of this problem is the attitude of human. The human attitude nowadays really disappointing. They do not have the love feeling to the nature and throw garbage or any chemical substances anywhere including the river, the sea and any water sources. So this chemical substance will harm the water and we as the user will use the water without notice that we use the contaminated water. Slowly or in the long term our body will be affected. Besides that. the excessive used of fertiliser also is the causes. This excessive fertilisers will flow towards to the water sources when it is raining. So the fertilisers will gather at a place and increase the level of nutrient at that place. So the algae will bloom and prevent the sunlight to enter the place and caused the the living things in the plase die. At last the acidity of the place will increase and the user will be harmed if use the high acidity of water. Secondly, the effects are the death of the aquatic animals. For examples the fish in the river will die if the irresponsible people throw
