    Biodiversity plays a significant role in the socio-economic development of man. Therefore, careful use of biodiversity is an essential requirement for sustained global development. However, available data points to a high rate of biodiversity loss especially in developing countries which has been attributed to a combination of human-induced factors, including rising demand for and consumption of natural resources. This paper identifies those human activities that result in irreversible loss of biodiversity using the Ifelodun Local Government Area of Kwara State as an example. A structured questionnaire containing information on the people’s activities influencing biodiversity loss, the effects of biodiversity loss, and socio-economic characteristics among other questions were randomly administered to 250 residents of the Local Government Area. Residents Agreement Index (RAI), descriptive statistics (frequencies and percentages) and, regression analysis were used to explain the causes and effects of biodiversity loss. Ten major activities were identified to be influencing irreversible biodiversity loss. They are, cattle rearing (1.21), logging (0.89), road construction (0.81), culture (0.79) and herb harvesting (0.59), poaching (-0.69), farming (-0.61), Industrial activities (- 1.59), energy generation (-1.32) and settlement development (-0.05). Theeffects of biodiversity loss include poor crop yield (43.2%), soil erosion (31%), a threat of desertification (12%), reduction in the number of wildlife (9.6%), reduction in timber production (4.2%). The results of the regression analysis show that biodiversity loss is a function of the socio- economic characteristics of people. The paper concluded that though the socio-economic development of a society is attached to its biodiversity exploitation, careful, diligent, and sustainable use of these resources is required.

    The Practice and Challenges of Biomedical Waste Management: A Study of Selected Medical Facilities in Ile-Ife, Osun State
    (Faculty of Environmental Sciences, University of Ilorin, 2018) Ola, A. B; Bako, A.I; Abdulraheem, M.O; Raheem, W.M; Raheem, W.A; Adewale, Y.Y
    In pursuing their aims of providing treatment and safeguarding the health of the people against illnesses, health-care services inevitably create waste that is hazardous to health and whose management has remained a great challenge due to its highly toxic contents. This paper examines the practice of biomedical waste management in some medical facilities in Ile-Ife with a view to determining the risks associated with the practice. Four medical facilities with some level of sophistication in waste management were purposively selected for study. The type of waste generated was determined by sorting of waste while hand held scale was used to determine the volume of waste generated. Questionnaire was used to obtain information from the waste management and medical staff of the selected medical facilities. Descriptive (frequencies and percentages) and inferential statistics (Multinomial logistic regression) were used in analysing the data. The study established that the daily per capita waste generation in the medical facilities was 0.51kg. Scrap (Syringes and absorbent paper) (96.7%), infectious (Excreta and dressing swabs) (72.9%) and pathological wastes (Human tissue and body fluid) (57.0%)were the most generated waste while open dumping and pit burial of waste were widely practiced among the medical facilities. Exposure to harmful chemical and radioactive waste (68.8%)and injuries from sharps (52.3%)pose serious health risks not only to the waste managers but health care workers. The paper holds that solutions to the challenges of biomedical waste management practices lie in strict adherence to the global best practices as recommended by the World Health Organisation.
