This biology assignment delves into three critical environmental issues: the greenhouse effect, the ozone layer, and climate change. The assignment defines each concept, explaining their importance and the problems associated with them, such as global warming, air pollution, and the depletion of the ozone layer. It explores the causes, including the burning of fossil fuels, chlorofluorocarbons, and human activities that increase greenhouse gases. The assignment also examines potential fixing strategies, such as reducing carbon emissions, using eco-friendly products, and international initiatives like the Montreal Protocol. Finally, it outlines the consequences of inaction, including melting ice caps, skin cancer, and disruptions to ecosystems and rainfall patterns. The student has used multiple resources to research the topics and answer the questions completely as per the assignment brief.
