So you've got a thing on the left, CO2, that you want to get to zero.
3
And that's going to be based on the number of people, the services each person's using on average, the energy on average for each service,
4
and the CO2 being put out per unit of energy.
5
So let's look at each one of these and see how we can get this down to zero.
6
Probably one of these numbers is going to have to get pretty near to zero.
7
That's back from high school algebra.
8
But let's take a look.
9
First, we've got population.
10
The world today has 6.8 billion people.

Wat is de Shadowing-techniek?

Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
