As the oceans get hotter, corals also become heat-stressed and expel the algae that live on their skeletons, resulting in coral bleaching events that can wipe out entire reefs. This destroys the habitat that supports a quarter of all marine life.

There are jobs to be created on both sides of the climate argument. Whether we are investing in oil or sun, coal or wind, gas or algae, the economy will be stimulated by the investment. The economy, unlike each of us, is not swayed by ideology.

If you're a beach person or a golfer, Key West is not for you. Most of the sand has been imported, and the water is shallow until you've waded far out, and all the way the sea floor is covered with yucky algae and sea grass.

Excess nitrogen from the fertilizers can cause eutrophication in the ocean, which can lead to harmful algae blooms or hypoxia - reduced levels of oxygen that create conditions in which organisms can't survive.

Cities might become biological entities, walls hung with curtains of algae that glow at night and sequester carbon, and floors made from tweaked cellular material that strengthens like bones as we walk on it.

Everybody is looking for a naturally occurring algae that is going to be a miracle cell to save the world, and after a century of looking, people still haven't found it.

Nearly all edible seaweeds - or 'sea vegetables,' as they ought technically to be called - belong to one of three broad groups: green, red and brown algae.

Algae commonly indicate water quality and ecosystem health in their habitats.

Water Environments

While often associated with green color, algae can also be other colors like red or brown.

Not Just Green

Algae can be undesirable, causing issues like pool contamination and clogging filters.

Not Always Welcome

Algae live in a range of waters, from salty oceans to fresh puddles.

Diverse Habitats

Algae play a crucial role in aquatic food webs as a primary food source.

Ecological Significance

Algal blooms can be harmful, affecting other aquatic life and water usability.

Blooms Impact

Algae use sunlight to make food, supplying oxygen to ecosystems.

Photosynthesis Producers

Unlike plants, algae don't have true roots, stems, or leaves.

Lack True Structures

Algae contribute to much of the Earth's oxygen, often more than trees.

 And you can have what we call organic molecules, and these are the bricks of life, and you can have fossils, and you can minerals, biominerals, which is due to the reaction between bacteria and rocks, and of course you can have gases in the atmosphere. And when you look at those tiny green algae
