Vertical farm provides food and water for 5o thousand people 　

The concept of vertical farm is “skyscraper style greenhouse”. The professor from Columbia University, Dickson·Dispomia composed a model of vertical farm that each farm has up to 30 floors and can provide food and water for 50 thousand people for one year and won’t produce wastes.

Marine fertilization 　

These marine fertilizations will stimulate plankton to swallow-carbon dioxide in order to bloom and grow by imposed nutrients such as iron and urea in the ocean surface or pumped into the deep sea.

Building the future deep-sea fishing 　

Some experts warn that: the ever-growing world population rapidly consumes the various types of seafood and has seriously depleted the fish resources in the world. Scientists have invented a remote farming cage for deep-sea fish farming. In future, seafood stocking can be even achieved after their mature then on the fishing.

To cultivate cow with more digestion

Cows digest about 68 kilograms grass, hay, silage and 9 kg of concentrative feed a day.

To emit sulfur into the atmosphere by man-made volcano eruption 　

When the Philippine volcano Mount Pinatubo erupted in 1991, it emitted 10 million tons sulfur into the atmosphere blocking sunlight and cooling the Earth. Including Nobel laureates Paul ? Reiter and many scientists believe that we can replicate this natural feat.

If the atmospheric particles can build space mirror to reflect sunlight

Enough to act as a mirror effect, reflecting sunlight to make the earth cooler, then why not use a real mirror? In this regard, the University of Arizona astronomy and optics expert Roger ? Angell said to do so. He advocated the 1.8 million square miles of sun mirror launched into orbit, the large mirror formed by the 16 trillion mirror cost of 5 trillion.
