outline some environmental issues
Use of resources: most resources are finite so we must decide how to use them in a sustainable way, which doesn't cause lasting damage. our over-consumption of energy means that others can't afford it and there's massive disparity between rich and poor in terms of resources. Over-exploitation of resources, e.g. overfishing, means that species like sharks are going extinct due to by-catch (50, mill sharks killed a year), sea beds are being destroyed, and people who rely on fishing for their livelihood are now being forced out of business as larger corporations move further out to find fish, e.g. Somali pirates
Climate change: increased levels of CO2 in the atmosphere has led to global warming, leading to more frequent extreme weather events, e.g. drought in East Africa, sea levels rising which will lead to Maldives being underwater, increased conflict due to lack of resources and also not enough action being taken due to lack of leadership, e.g. Trump saying that the Chinese fabricated global warming and disagreements between scientists, e.g. in 2009, emails were leaked between scientists which suggested that they were fabricating data to support human-caused climate change. This has led to many people not believing in climate change and 'environmental fatigue' (people getting bored with these issues), e.g. 25% british people said they didn't believe climate change was taking place
Wildlife conservation: resource depletion and climate change leads to loss of habitats which is leading to animal and plant species being threatened/extinct. some animals are also targeted for human benefit, e.g. ivory of rhinos and elephants, only 3 white rhinos now exist as ivory seen to be beneficial in Chinese medicine.. our over-consumption, e.g. for coltan needed to produce phones has led to gorillas being threatened in the East Congo.
other issues include: plastics, waste management, air,water,light and noise pollution, deforestation and non-renewable resources.
