QUESTION

1

Only a handful of British species turn white in winter to blend with the expected snow and hide from predators. The mountain hare is perhaps the most impressive and by November will have shed its brown coat to become blue-ish white.

QUESTION

2

The carbon footprint of something (a person, a business, or country for example) is a measure of how much carbon they use during a certain period of time - usually measured per year. The carbon footprint of a person during one year would consist of the total amount of carbon dioxide released into the atmosphere by all of the activities they take part in, and the manufacture, use and disposal of all the products and resources they use.

QUESTION

3

Between 20-30% of UK power is generated by using the movement of wind. Wind power contributed 20% of UK electricity generation in 2019, making up 54% of electricity generation from renewable sources. In 2020 wind power rose to 30% of the UK’s electricity in the first quarter, beating the previous record of 22.3% set in the final months of 2019.

QUESTION

4

The world uses over 500 billion plastic bags a year – that’s 150 for each person on Earth. (Source: https://www.condorferries.co.uk/plastic-in-the-ocean-statistics)

QUESTION

5

Estimates vary so wildly this question is impossible to answer with any certainty (don't worry you get the points anyway!) The IPBES Global Assessment Report on Biodiversity and Ecosystem Services is the most comprehensive ever completed. The report was compiled by 145 expert authors from 50 countries over three years, and found that around 1 million animal and plant species are now threatened with extinction, many within decades, more than ever before in human history.

QUESTION

6

Trees and shrubs have years where they produce a bumper crop of their fruits or nuts. This is called a mast year. The length of time between mast years varies between species. Our native plants and animals have evolved together over thousands of years, so their lives are inextricably linked and reliant on one another. Oak trees produce acorns to ensure the next generation of trees, but in doing so provide a vital source of food for many birds and small mammals too.

QUESTION

7

The number of the house sparrow, starling and song thrush has gone down by more than half over the last 25 years. While some of this is because of changes in farming practices, in the cities and towns scientists think a loss of insect food could also be to blame. This means we need to make sure our gardens are full of insects for these birds to eat.
