Destruction of bio diversity has become one of the prominent problem today. At present humans are engaged in various activities and the destruction of the bio-diversity is the main problem. Nowadays, people do everything to get an economic profit. They do not think about the environment which gives them their daily needs. So the bio-diversity destruction gets a prominent palace. The harmful effect of this situation has created problems for the existence of all beings on the earth. So the main objective of this project is to do a complete research of the destruction of the bio-diversity.
The present world continues its activities with technological and scientific methods. As a result of this the environment is fully destroyed. The bio-diversity which supplies all the needs of living beings is at danger. This crucial situation can be seen in Sri Lanka at large. At present, we can see a large number of development activities in Sri Lanka. Though these development projects are being carried out, they have affected the bio-diversity of our country. A large number of mangroves are destroyed for these purposes. And also the harmful chemicals and undecaying materials are sent to waterways. The illegal fillings of marshy lands have caused a lot of damage to the environment. Because of this reasons, the bio-diversity of wet lands has been destroyed. At the same time, the drinking water has been polluted. And also, various types of diseases can be spread. It also damaged the aquatic lives such as fish, watery birds, plants etc. When the mangrove of a lagoon is destroyed, it affects the sea. The mangroves stand as a buffer against sea-erosion. As it was mentioned earlier, the main purpose of this research is to study about the harmful result of the destruction of the bio-diversity. It is expected to bring forth some suggestions to minimize this crucial situation.
To collect preliminary data for this research, I have selected the Munnakkaraya area which is in the neighbourhood of Negombo. This is an area which has faced the worst destruction of the bio-diversity.This research has helped to identify bad effect of the destruction of mangroves. The improper human activities of this area have caused a lot of problems for the existence of the living beings, especially very closer to the sea area.
The unlimited destruction of mangroves has made the condition worse. The socio-economic activities of the people in this area have created problems for themselves. And it will affect the bio-diversity of this area in the near future too. At the end of the research, many suggestions were proposed to make them understand the harmful effects of the destruction of bio-diversity which is their main supporter. They were advised not to dump garbage into the lagoon, not to build houses closer to the lagoon, not to overuse the resources in the lagoon. They were given a thorough understanding of the value of bio-diversity which is their livelihood. |
