Amy Jankiewicz says the government must address the effect of global increases in population and unsustainable consumption patterns as intertwined challenges George Monbiot’s article (The UK government didn’t want you to see this report on ecosystem collapse. I’m not surprised, 27 January) highlights the grave risks identified in the UK government’s report Global biodiversity loss, ecosystem collapse and national security. However, it overlooks a key factor highlighted in the report – that population growth is a major indirect driver of global biodiversity loss. “As the global population grows, reaching 9.7 billion by 2050, the impact of food production on natural systems will intensify and it will become even more challenging to produce sufficient food sustainably,” it says. Mass-scale expansion of agriculture driven by global population growth risks sacrificing sustainability: forests cleared for farmland, pesticides polluting waterways, and ecosystems pushed beyond recovery accelerating biodiversity loss. It is a concern echoed by the United Nations Intergovernmental Panel on Climate Change, which identified population growth and GDP per capita as the strongest drivers of carbon emissions.
