WHICH IS THE MOST USED RENEWABLE ENERGY IN THE WORLD:

Hydropower

Solar power

Wind power

Score:992340

Right answer!

Hydropower accounts for 19% of total global electricity production, and 13% in France. It is the most used source of renewable energy, and the hydroelectric potential in the world has not yet been fully exploited. Solar energy accounts for 3% of global renewable energy production. Wind power is estimated at 4% of global electricity production

SINCE 1979, SEA ICE HAS DIMINISHED BY:

10,000 km2 each decade (or 1,000 football pitches)

1 million km2 each decade (or 100,000 football pitches)

Score:992340

Right answer!

The oceans are warming, snow and ice is melting and sea levels are rising. Between 1901 and 2010, average global sea levels rose by 19 cm as the oceans have increased in size due to warming and melting of the ice. Since 1979, 1.07 million km² of Arctic sea ice have been lost each decade.

QUESTION 9/10

HOW MANY CULTIVATED PLANTS HAVE DISAPPEARED IN THE LAST CENTURY?

Score:992340

Right answer!

Since the start of the century, 75% of the genetic diversity of cultivated plants has been lost. We are increasingly dependent on an ever decreasing number of crop varieties and, consequently, ever less abundant genetic reserves. This is resulting primarily in the substitution of traditional varieties with uniform commercial varieties. And yet biodiversity is essential for health, food security and ecosystem maintenance.

QUESTION 10/10

OF ALL KNOWN ANIMAL SPECIES…

3% are already extinct and 12% are facing extinction

6% are already extinct and 16% are facing extinction

8% are already extinct and 22% are facing extinction

Score:992340

Right answer!

The way in which we treat our planet has a considerable effect on global biodiversity. Of all the animal species known, 8% are already extinct and nearly 22% are at risk of becoming so in the near future. However, biodiversity includes more than just animals. The world is home to more than 80,000 species of tree and numerous microsystems. All these species have a role to play in maintaining the natural, fragile balance.
