Phytoplankton are microscopic algae living throughout the ocean’s surface waters. They can’t swim and are at the mercy of the currents and tides. Despite their small size, phytoplankton enable life in the oceans – and throughout the planet – to exist.
There are two types of plankton – zooplankton, which are animals, and phytoplankton, which are algae. Phytoplankton are filled with chlorophyll which gives them a green colour, just like land plants. And like land plants, phytoplankton play a critical role, converting carbon dioxide and energy from the sun into food through photosynthesis, producing oxygen. ....

These tiny organisms have been producing oxygen for the world for hundreds of millions of years. But most people know very little about them, what they do for the rest of the world and the threats they are facing. ....

Have Microplastics Reached a 'Steady State' in the Ocean? Envirotech Online


Feb 22 2021 Read 1087 Times
It’s common knowledge that our consumption of plastic has continued to increase over recent years and decades, with much of the plastic generated only designated for single-use purposes. While governments across the globe have attempted to introduce schemes to curb the improper disposal of plastic waste, recycling rates remain depressingly low and a significant proportion of all plastics eventually find their way into our seas and oceans.
Despite these discouraging premises, it may be possible that the overall amount of plastic in our marine environments has levelled off in recent years. Those are the findings of a study conducted by the French oceanographic research institute IFREMER, which pored over a wide range of previously existing marine litter data to come to its conclusions. However, lead author Dr Francois Galgani was quick to temper any optimism that may be engendered from the paper, given that alternative explanations do exist. ....
