profits for humans. Of course‚ not only commerce is to blame. Hunting as a sport has also played a part in the extinction of certain species. A more modern threat to many animals is the destruction of their environment and the resultant changes in the ecology of whole areas. Our use of pesticides and other chemicals has polluted both soil and water‚ and this pollution has proved to be toxic to many of the plants which are part of the habitat of many animals. Furthermore‚ we regularly lay waste to land

The scope of the biology includes the study of all these and may extend to the level of the organism such as behavior‚ and the organism mechanism for interacting with its environment. Ecology started from the study of the organism-a group of organisms that is similar in appearance‚ behavior and genetic make up belong to the same species.

Exotic plant invasions are causing profound changes to ecosystems around the world. However‚ it is difficult to generalise about their effects on ecosystem properties‚ since these vary according to the traits of the invading species‚ and the properties of the invaded vegetation and habitat. Yet‚ knowing the inherent functional traits of an exotic invasive plant could improve understanding of its invasion success and impact‚ since plant traits affect ecosystem properties such as through fall distribution

Introduction The state of the world today is under a great amount of stress. This is mainly due to the evolution of man and their usage of the space they inhabit (Nickerson 2003). Due to humans increasingly invading and destroying natural areas‚ current environmental problems are induced and they include: global warming‚ acid rain‚ air pollution‚ waste and deforestation (Nickerson‚ 2003). These issues have a detrimental effect on more than a handful of species and ultimately cause a reduction in

stumbling blocks which we are encountering with in our international effort to achieve sustainable development. 2. What is sustainable development To start with this concept I prefer to define ecology in the first step since it is related to sustainable development.
