Live Green - Simply Wood Rings Are Simply Too Cool
┬╗ Workshop on Challenges on Vertical Farming The Problem By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA).

Breathingearth - CO2, birth & death rates by country, simulated real-time

The Breathing Earth simulation Welcome to Breathing Earth. This real-time simulation displays the CO2 emissions of every country in the world, as well as their birth and death rates. Please remember that this is just a simulation. Although the CO2 emission, birth rate and death rate data used in Breathing Earth comes from reputable sources, data that measures things on such a massive scale can never be 100% accurate. Please note however that the CO2 emission levels shown here are much more likely to be too low than they are to be too high.
