Drag and drop the boxes into the correct order.

Order the following sentences about the oceans.

This means that the oceans are more acidic (ocean pH has dropped from pH 8.2 – before human activity – to pH 8.1).
These two factors in mean that the ocean's capability to provide important ecosystem goods and services – such as climate regulation – is reduced.
The oceans have absorbed about a quarter of our emissions from fossil fuels.
Oceans are also warming – this limits the amount of CO₂ they can store, and also leads to coral bleaching and eventual death.
An increase in acidity means there are fewer calcium ions for organisms to build shells. This affects corals and some marine creatures, including plankton. Carbonate shells are also more readily dissolved.

This is your 1^st attempt! The marking algorithm gives more marks for getting the right order first time.
