Our climate didn't begin to deviate from its usual fluctuations until the 1990s. Why was that?
The oceans had been absorbing the excess heat.
Levels of carbon in the atmosphere were safe before the 1970s.
The hole in the ozone layer caused some Antarctic ice to melt.
Feedback loops were triggered in the 1980s.
According to Attenborough, over 1/3 of mammals are humans; what category of mammals, at 60%, makes up the largest proportion on Earth?
Livestock
Wild land animals
Domestic pets
Marine mammals
Attenborough claims that science predicts that by the 2030s, the Arctic will be completely free of ice in summers. Which of the following will occur as a consequence of this?
Half a million species will be wiped out.
Global warming will decelerate.
Global warming will accelerate.
Polar bears will migrate to Antarctica and live on penguins.
Frozen soils in the planet's north have locked up which powerful greenhouse gas, that the melting of the soils would release into the atmosphere?
Methane
CO2
Nitrous oxide
Ozone
Scientists predict the Earth will be 4 degrees Celsius hotter by the 2100s, according to David Attenborough. Which of the following constitutes what one outcome of this will be?
Antarctica will become a tropical paradise.
Humans will become extinct.
More land will become inhabitable.
Much of the planet will become uninhabitable.
To reduce climate change, Attenborough recommends we begin to obtain our electricity from solar, wind, water and which other source?

We can rewild the oceans by increasing fish populations (including for consumption) by which of the following means?
Farming fish
Making one third of coastal seas no fish zones and restricting fishing
Overfishing predatorial fish species
Shouting at whalers
David says that if we don't change the way we use land and preserve biodiversity, the trend is for a bleak future. Among the forecasts cited it can be stated that:
The Amazonian forest, whenever deforested, will recover, maintaining the humidity of the air.
The frozen soils of the North will melt, releasing enough oxygen into the atmosphere.
Among the pollinators, only insects will remain.
Acidification of the oceans and death of the world's coral reefs.
A negligible increase in world temperature.
In the film there is evidence of serious environmental problems. Tick those that may have been caused directly or indirectly by man:
Deforestation for monocultures.
2/3 reduction of the orangutan population in Borneo.
Consumption of 30% of fish by overfishing.
80% reduction in drinking water worldwide.
1ºC increase in world temperature.
