World Environment Day 2012 Today

World Environment Day has arrived on Tuesday this year spreading public awareness of global environmental concerns.

Celebrated every year on June 5, this year marks the 40th observance of the event, organized by the United Nations in 1972. World Environment Day is for initiating solutions on environmental issues.

Widely known as Environmental Day, the event boosts knowledge about preserving our biodiversity. Every year, the United Nations Environment Programme (UNEP) selects a theme which draws attention to specific ecosystem management.

This year's theme is "Green Economy: Does it involve you?" The UNEP explained that a green economy is "one which is low carbon, resource efficient and socially inclusive," according to the official website.

Additionally, the UN Environment Programme calls on "targeted public expenditure, policy reforms and regulations changes" in order to "reduce carbon emissions and pollution, enhance energy and resource efficiency."

"The question therefore asks you to find out more about the green economy and assess whether, in your country, you are being included in it," the UNEP stated.

Many people across the globe are celebrating World Environment Day with great enthusiasm. Groups as well as individuals are attending events supported by governments that share ideas to tackle problems including natural disasters, global warming, and pollution.

Also, the event is celebrated around the world with bicycle parades, green concerts, and tree planting.

On Twitter, users are sounding off about World Environment Day and acknowledging the purpose behind the event.
