Small issues can have massive results. Take the plant plankton that populate the Earth’s oceans. When zooplankton eat them, the phytoplankton launch a chemical known as dimethyl sulphide (DMS) and it’s this that persons are referring to after they converse of the “scent of the ocean”. Chemical reactions within the environment flip DMS into sulphur-containing particles that provide a floor for water vapour to condense on. Do this sufficient instances and the result’s a cloud. Clouds, in flip, have an effect on each the native climate and, by reflecting daylight into house, the world’s local weather.
