World Environment Day 2014: Tweet Your Heart Out About Rising Sea Levels, Environmental Causes

It's World Environment Day and millions of people, companies and organisations around the world are taking to Twitter to spread the word about going green in order to tackle big challenges like the rising sea levels facing small islands.

You can join them too by tweeting using the hastags #WED2014 or #WorldEnvironmentDay, or pick a a team out of the four United Nations Environment Programme ambassadors and take up a WED Challenge.

There are 38 UN member states and 52 island states in the world that are acutely vulnerable to environmental degradation, climate change, overexploitation of fisheries resources, land-based pollution and natural disasters.

It's not enough for just these countries to go green and practice environmentally friendly practices – every single country in the world is encouraged to get involved to cut carbon emissions, clean up and preserve rainforests, green spaces and the ocean; find renewable and environmentally-friendly sources of energy; recycle and much more.

Join us as we take a look at some of the topics people are most concerned about on Twitter today:

1. Rising Sea Levels

By 2100, it is estimated that the sea levels will rise by up to two metres, meaning that nations such as Kiribati, Maldives, Marshall Islands and Tuvalu would become completely uninhabitable. This problem is caused primarily by climate change and the UNEP has made this a key issue to work on this year:

2. Go green and recycle

There are many small ways you can help the environment, by going green, meaning you make an effort to recycle, and also use products that are not toxic and will not damage the environment in landfill or add to carbon emissions depleting the ozone layer:

3. Decrease wastage of resources

Another way you can help to save the environment would be to stop wasting. Turn off anything using electricity to save energy, one of our most valuable resources. Stop wasting food – a third of food produced is wasted, and we had to sacrifice forests for the fields to house cattle in, and the cattle contribute to CO2 emissions. Not wasting can go a long way to helping the environment:

4. Plant more trees

There are lots of projects around the world to increase the number of trees being planted, which can dramatically help to counteract carbon emissions:

5. Stop polluting

A lot of people are talking today about stopping pollution, which is one of the biggest problems affecting our environment:
