What happens if there is no vegetation

In this TedX film scientist Greg Asner explains how he equipped a plane with the fantastic monitoring equipment and what this enabled him to learn about natural behaviour and ecosystems, especially in forests. List of air filtering plants. Green pays off! How To. What is our waste? How do plants do that, exactly?

The climate The climate is changing and the main reason for this is the ever increasing amount of CO 2 in the atmosphere caused by our intensive lifestyle. Ability to purify air is too unknown The fact that plants also process this waste very effectively, converting our particulate toxins to harmless, usable substances, was only discovered some 20 years ago and is not yet very widely known.

By this stage, humans would probably be the only mammals remaining, because of our substantial food stores though rats and mice could maybe also access ours. Cold-blooded animals have lower food requirements, but with supplies dwindling, their days would also be numbered.

We would be long gone before the oxygen ran out. They are at the bottom of the food chain, so life in the oceans would continue. But even if phytoplankton survived, the oceans would only be able to support a small fraction of the global population, even if we harvested food more sustainably.

However, our species might survive at these much-reduced numbers. Even if oxygen was used up at the current rate, it would last about years. And if there were few humans and no other life on Earth, oxygen may take half a million years to fall to a level that would make breathing difficult, suggests James Lovelock, originator of the Gaia hypothesis.

Energy could be harnessed for the electrolysis of water to split its molecules into oxygen and hydrogen, with the oxygen discharged into the atmosphere for us to breathe and the hydrogen used for the chemosynthesis of food. But we would need to look to space programmes to ensure long-term human survival. These are researching how to feed astronauts on long space flights, for which conventional food crops will probably be replaced with chemosynthetic farms where autotrophic bacteria can feed on chemicals to produce carbohydrates.

Something like this already happens naturally. Microbes in hydrothermal vents at mid-ocean ridges kilometres below the sea surface can make food in the absence of both light and oxygen.
