Journey to planet Earth. State of the planet
Description
Are populations soaring out of control? Today the Earth's population has surged to nearly 6.5 billion and is increasing by nearly 80 million people each year. Yet the population explosion that began in the mid 1900s is finally slowing down - and it is happening in some of the most unexpected places. Are we running out of water? Over 97% of our planet's water is undrinkable seawater and another 2% is locked up in polar ice caps. Coupled with the fact that the demand for water doubles every 20 years, this does not bode well for the state of our planet, especially in the mega-cities of the world. Will there be enough water and food for future generations? In the last three decades we have increased available food per person by almost 20%, yet more than 800 million people still go hungry each day. Global warming - a false alarm or a gathering storm? Today the level of carbon dioxide in the atmosphere is higher than it has been for hundreds of thousands of years, and global temperatures are rising faster than at any other time in recorded history. The consequences of these human-induced changes are becoming more and more profound. The State of the Planet visits parts of the world which suffer from human overcrowding, hunger, despair and rampant disease, but it also introduces stories of hope and courage, celebrating the beauty and diversity of the natural world.
