A serious blue-green algae warning for Lake Tuggeranong, Australia s Lake Burley Griffin, was raised.
Canberrans were told to stop swimming in two of the favorite lakes in the area. But, shocking discoveries were made that links the said algae in the attempt to make Mars habitable.

Snows in some parts of Antarctica are turning green from blooms of algae thriving in the snow. Green snow algae grow mostly on Antarctic coastlines, in areas where it is warmer.
Algae in Canberra
Access Canberra released an extreme warning for blue-green algae in Lake Tuggeranong. Simultaneously, in a water safety survey conducted on February 1, the National Capital Authority discovered water in Lake Burley Griffin was contaminated by blue-green algae.

Now that NASA has successfully put the Mars 2020 Perseverance rover on the surface of the Red planet, all eyes are on the ambitious plan to someday send a manned mission there.

Key Highlights The Cyanobacteria that were largely responsible for the creation of a breathable atmosphere on Earth 3.5 billion years ago could be deployed into creating human-friendly atmosphere on other planets.
A team of biologists and chemists has been investigating the ability of these cyanobacteria – also known as blue-green algae to photosynthesize in low-light conditions.

A major pathway for carbon sequestration in the ocean is the growth, aggregation and sinking of phytoplankton - unicellular microalgae like diatoms. Just like plants on land, phytoplankton sequester carbon from atmospheric carbon dioxide. When algae cells aggregate, they sink and take the sequestered carbon with them to the ocean floor. This so called biological carbon pump accounts for about 70 per cent of the annual global carbon export to the deep ocean. Estimated 25 to 40 per cent of carbon dioxide from fossil fuel burning emitted by humans may have been transported by this process from the atmosphere to depths below 1000 meter, where carbon
