The study examined the crux about global warming, greenhouse effect and ozone layer depletion among pre-service biology teachers. A survey questionnaire adapted from Kalipit, Yener & Ozkadif (2009); Rye, Ruba & Wiesenmayer (1997) and Boyes, Chambers & Stanisstreet (1995) was administered to 65 pre-service Biology teachers purposively selected from the Department of Science and Technology Education, Lagos State University, Lagos. This was to determine the pre-service biology teachers’ perceptions about global warming, greenhouse effect and ozone layer depletion. Data collected were analyzed using descriptive statistics. Results showed that pre-service Biology teachers had misconceptions that the results of thinning of ozone layer will increase greenhouse effect and the function of ozone layer is to protect the earth against excessive heat. Furthermore, majority of the preservice biology teachers had misconceptions on global warming, ozone layer depletion and greenhouse effect. It is imperative, therefore to proffer solutions to these misconceptions held by the pre-service teachers by ensuring that instructors and instructional materials emphasize the importance of these concepts to life ensuring that students have adequate knowledge about the concepts as well as ways of tackling these challenges.

<p class="apa">The aim of this research is to investigate student science teachers’ opinions about the causes of degradation of ecosystems and the effects of such degradations on the environment. This research focuses on the following questions: What kind of descriptions do student science teachers ascribe to the reasons of degradation in ecosystems? What are the effects of ecosystem degradations on the environment? What are the misconceptions in relation to degradations in ecosystems? A total of 130 participating students, who were studying to become science teachers at Faculty of Education of Necmettin Erbakan University in Turkey, participated in this study. To reveal the participating students’ opinions about the reasons for degradations in ecosystems and their effects on the environment, they were asked to answer two open questions: (1) What are the reasons for degradations in ecosystems? (2) What are the effects of degradations in ecosystems on the environment? The participants were asked to answer these two questions. Data obtained from the questions were analyzed and the frequencies of the answers were classified in different categories. Moreover, these included some misconceptions such as ‘the greenhouse effect can lead to skin cancer’ and ‘ozone layer depletion leads to global warming’. The findings are compared with related literature and suggestions are presented.</p>

Global Environmental Issues

The present study aims to investigate prospective teachers’ (PTs’) and secondary students’ (SSs’) ideas related to environmental issues. A case study design was adopted in this study. SSs (n = 100) who received instruction on environmental issues and PTs (n = 150) who attended courses concerning environmental education were participated in this study. An open-ended questionnaire was designed and used as a data collection tool. Written answers of the participants were analysed in ideographic terms. The results of the study showed that the PTs held a range of alternative ideas similar to SSs. They both linked environmental problems which were irrelevant with cause–effect chain. Yet, PTs provided a more scientific definitions regarding greenhouse effect, global warming and ozone layer depletion as compared to SSs.   Keywords: Global environmental issues, prospective teachers, secondary students, environmental education, greenhouse effect, global warming, ozone layer depletion.

Kota Malang memiliki jumlah penduduk yang ditiap tahun meningkat, menyebabkan jumlah timbulan sampah dihasilkan oleh penduduk maupun fasilitas umum meningkat. Sampah diangkut ke Tempat Pemrosesan Akhir (TPA) sampah Supit Urang berlokasi di Kecamatan Sukun, Kota Malang, saat ini pengolahan masih menggunakan metode Controlled landfill sehingga dibutuhkan lahan yang luas untuk proses penimbunan. Pengambilan data timbulan sampah TPA dengan metode load count analysis. Analisis aspek lingkungan dilakukan dengan metode Life Cycle Assessment, input dan output proses digunakan software SimaPro v.9.0.0.47. Pada analisis aspek teknis serta analisis lingkungan dibutuhkan proyeksi sampah masuk pada TPA Supit Urang yaitu 189.989 ton/tahun pada tahun 2030. Dari hasil analisa aspek teknis dihasilkan, yaitu pengolahan insinerasi jenis sampah tercampur adalah paling baik karena hanya butuhn lahan sedikit yaitu sebesar 1.385m2, menggunakan 1 reaktor dan 14 orang pekerja. Untuk jenis komposisi sampah yang menghasilkan emisi paling rendah adalah jenis sampah organik biowaste. Hasil analisis dampak lingkungan dari pengolahan gasifikasi sampah organik biowaste adalah Global Warming 4,51E8 kg CO2 eq, Ozone layer depletion 1,74E3 CFC-11 eq, Photochemical oxidation 1,11E5 C2H4 eq, Asidifikasi 2,21E6 kg SO2 eq, Eutrofikasi 3,03E6 PO4 eq
