Climate change and food production

Science

Pupils will learn about biomass transfer including calculating the efficiency of transfers between trophic levels. They will learn about human impacts on the environment, food security and biotechnology to help maintain biodiversity and achieve food security.

In the Climate change and greenhouse gases unit, pupils learnt about greenhouse gas emissions from transport and industry, and the use of renewable energy resources and changes to transport infrastructure that could reduce emissions.

In this unit pupils learn about the impact of agriculture and deforestation on biodiversity, and to more thoroughly consider the effects of climate change on biodiversity and food production.

According to the bar chart, which stage of producing rice contributes the most emissions to rice’s carbon footprint?

According to the bar chart, which food generates the largest amount of emissions from animal feed?

Which meal is likely to have the lowest carbon footprint of emissions and therefore be the best choice to help limit climate change?

True or false? Buying fish instead of pig meat will reduce emissions.
