Super plants that can save the planet

Plants are living and among other functions, are a source of food, shelter,
oxygen, etc. We present seven super plants for its amazing features
that can help save the planet and are also the most common in the
world.

Seaweed


From single cell to giant kelp over 100 feet in length have a rapid growth
rate that has become a focus of biological research. They grow so
fast that their crops are weekly and not annual.

Some are edible and contain nutrients that have few crops, others function
as organic fertilizer and some species even serve as biological
filters for wastewater. Seaweed can grow in salty, shallow water, and
its potential is comparable to fuel oil, 15,000 km2 of algae could
supply the fuel needs of the United States.


Azolla


The Azolla is a small floating fern that develops in the wetlands around
the world. A single fern Azolla measures less than an inch, but their
growth rate is one of the fastest in the world, doubling in size
every two days in hot water from the surface. This trick has a
scientific explanation and is made possible by its ability to absorb
nitrogen from the atmosphere, which makes it a natural fertilizer for
immediate action.

The azolla serves as a kind of organic fertilizer, bio-energy source and
sustainable alternative livestock feeding replacing corn or soybeans.
Growth is also studied to develop a carbon sequestration technique.


Perennial
Wheat



Since cereals are part of the staple diet of millions of people worldwide,
annual crops require large amounts of water, fertilizers, including
pesticides and herbicides. The work of these crops planted annually
erodes the soil, so some years working in a variety of perennial
wheat called Kernza to replace the annual wheat and soil is used more
efficiently, which would give a higher yield of food.
