In this age of global climate change, and amongst the deniers, te taiao – the environment, is ever-changing and ever-important. It has recently come to the fore in a hugely political movement, globalised since the first speech of Swedish teen activist Greta Thunberg. This blog series will look at three aspects of climate change. Firstly, the scoop on global climate change issues, secondly on local or Aotearoa-based climate issues and thirdly, how yourselves as rangatahi can enact change against the climate crisis.
Firstly, the global picture
Acidification of our oceans
Due to the vastly industrialised world, and the ever-increasing pollution from factories and car exhausts, our oceans are becoming acidified. This is because the oceans absorb 30 per cent of the carbon dioxide released from land use and emissions (Ocean Service, 2020). It means we have less organisms in the sea, and people’s livelihoods will be affected. The behaviour of non-calcifying creatures are also affected, leading to different catchments being available. It affects directly the coral reefs, which provide amazing habitats for many sea-going creatures, and the acidic waters are actually dissolving some sea creatures shells right now (Bennett, 2020).
Salinity of water bodies i.e. lakes
Due to the salination effects on waterways from climate change, the waterways have increased in temperature about 2-4 degrees since the 1960s (Cheng L. et al. 2020). This has meant an ever-increasing salination rate, causing widespread damage to local aquatic and marine populations. What this means is that areas will become drier than before, eliminating vital habitat for various creatures, and a lessening of resources for humans to consume.
