[00:00.98]C So why is nature beginning to turn on us?

[00:05.71]One answer is over-population.

[00:07.86]The population of the world

[00:09.12]is growing at the rate of 10,000 people

[00:11.54]an hour,240,000 every day,

[00:15.91]nearly 90 million a year,

[00:18.52]with most of the growth in the developing world

[00:21.31]People in agricultural areas,

[00:23.69]unemployed and sometimes undernourished,

[00:26.47]move to the cities,and then set up unstable 1,

[00:29.69]sub-standard homes on poor soil

[00:32.03]which can easily collapse 2 in earthquakes

[00:34.35]or slide downhill in landsides.

[00:37.36]On top of that,add climate change

[00:39.99]and the spectre of globle warming.

[00:42.42]This has mainly been caused

[00:43.65]by the mismanagement of the world's resources:

[00:46.66]carbon emissions 3 from rich countries;

[00:48.90]the activities of the

[00:49.83]big multi-national companies;

[00:52.45]the deforestation for the world's forests.

[00:55.30]As a result,a hotter ocean leads to fiercer

[00:58.34]typhoons and hurricanes.

[01:00.23]Greater quantities of water evaporate,

[01:02.52]and more powerful winds dump this water

[01:05.36]against mountainsides with increasing strength.

[01:08.47]Atlantic hurricanes,

[01:09.82]for instance, are 40% stronger now

[01:13.11]than they were 30 years ago.

[01:14.29]
