Dolphins: surviving the Deepwater Horizon oil spill | Photo: Steve Shippee

The Deepwater Horizon oil spill in the Gulf of Mexico is still killing dolphins, sea turtles and other marine life in record numbers.

Infant dolphins are dying six times faster than they did before the 4.9 million barrels of oil got spilled in the Gulf of Mexico.

"These ongoing deaths - particularly in an apex predator like the dolphin - are a strong indication that there is something amiss with the Gulf ecosystem," explains Doug Inkley, senior scientist for the National Wildlife Federation.

World Water Day: share and protect our H20

The World Water Day is celebrated on the 22nd May 2013, with over 780 million not having access to improved sources of drinking water and 2.5 billion people living without improved sanitation.

By 2025, water withdrawals should increase by 50 percent in developing countries and by 18 percent in developed countries. Water for irrigation and food production constitutes one of the greatest pressures on freshwater resources.

An estimated 148 states share a basin with one or several countries, which is a potential source of conflict, as actions upstream have impacts on downstream countries.

Glaciers: melting fast

Twenty percent of all the ice contained in Canada's glaciers could melt by the end of this century.

The study developed by Geophysical Research Letters has reached a dramatic conclusion. If global average temperatures rise three degrees Celsius and by eight degrees in the Canadian Arctic, sea levels may go up by 3,5 centimeters.

If 20% of Canada's glaciers melt, this means 75% more water than previously thought. Also, when combined with melting glaciers such as those in Greenland, Russia and South America, the situation gets worse.
