World Earth Day calling: More concernes about environmental crisis

Today is World Earth Day. It's the 39th day of action in response to the growing concerns about an environmental crisis.

The day is meant to increase awareness and encourage people and governments to care more of our environment and take action to save our planet.

The earth catches cold, a human disaster. The winter storms in South China left a lasting image among Chinese people.

But our earth is suffering more than this. Air pollution, water shortages, global warming, and the extinction of species are adding scars to our planet.

As both makers and victims of environmental disasters, humans are key to its healing. April 22nd 1970 saw the first large-scale public environmental movement in human history.
