[MCN] Human population is controlled by food supply : the case of vanishing fish

[Lance Olsen]

Excerpt: Among lake ecosystem services, fisheries are especially vulnerable to environmental changes because fish are ectothermic and fish distribution is usually limited by structural6 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR6>, thermal7 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR7>, and chemical8 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR8> barriers. Environmental changes driven by climate and land-use changes have been linked to major shifts in fish catches (CATCHs) and species composition in many lakes around the world, such as lakes Erie9 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR9>, Kinneret10 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR10>, Naivasha11 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR11>,12 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR12>, Peipsi13 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR13>, and Victoria14 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR14>, as well as the collapse of Aral Sea fisheries15 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR15>. Reduced lake CATCHs caused by climate and land-use changes can threaten food security and livelihoods of millions of people worldwide, especially in impoverished countries where rural poor communities may not have appropriate alternative sources of animal protein and employment opportunity16 <https://www.nature.com/articles/s41467-020-14624-2#ref-CR16>.

Lasting coastal hazards from past greenhouse gas emissions <https://www.pnas.org/content/early/2019/11/06/1917051116>

The emission of greenhouse gases into Earth’s atmosphere is a by-product of modern marvels such as the production of vast amounts of energy, heating and cooling inhospitable environments to be amenable to human existence, and traveling great distances faster than our saddle-sore ancestors ever dreamed possible. However, these luxuries come at a price: climate changes in the form of severe droughts, extreme precipitation and temperatures, increased frequency of flooding in coastal cities, global warming, and sea-level rise (1, 2). 

This is the price we pay for the luxury of about 200 y of relatively unchecked greenhouse gas emissions.

From Energy Transition to Energy Reduction <https://www.resilience.org/stories/2020-05-20/from-energy-transition-to-energy-reduction/>
By Chris Smaje
My request to those working in the renewable energy industry is to ask themselves before undertaking any new project: “Will this help people to live a lower energy lifestyle than they previously did?” – which, regrettably, is not something we can say of the low carbon energy installed globally to date. If they can’t answer yes to the question, I’d request they dump the project and seek another one. It’s urgent.

It's too easy to blame the corporations for the climate crisis, when we subsidize them every time we buy what they’re selling. Corporate policy does matter. At the same time, they are totally dependent on their customers. This buck stops everywhere.
