Why you should be a climate activist

I never planned
to become a climate activist,

but now things have changed,

and now, standing here
as a climate activist,

I ask you all to become one too.

Here's why,

and most importantly, how.

Ten years ago, when I was 13 years old,

I first learned about
the greenhouse effect.

Back then, we spent
90 minutes on this issue,

and I remember finding it quite irritating

that something so fundamental

would be squeezed
into a single geography lesson.

Some of this irritation remained,
so when I graduated from high school,

I decided to study geography

just to make sure I was on the right track
with this whole climate change thing.

And this is when everything changed.

This was the first time
I looked at the data,

at the science behind the climate crisis,

and I couldn't believe what I was reading.

Like many of you,

I thought that the planet
wasn't really in a good state.

I had no idea that we are rushing
into this self-made disaster

in such rapid pace.

There was also the first time
I understood what difference it makes

when you consider the bigger picture.

Take the CO2 concentration
in the atmosphere, for instance,

the number one driver for global warming.

Yes, this looks bad.

This looks like we are on
a pretty bad track,

but it's only once you don't
just consider the last 60 years,

but the last 10,000 years,

that you understand
how terrifying this really is.

And this is just one aspect
of the crisis we are seeing.

I'm not going to get into details here,
but let me tell you so much:

we are in a point of history

that the most destructive force
on the planet is humanity itself.

We are in a point of history

that no scientist could guarantee you
that you will survive this.

We are in a point of history

that humanity is creating an environment

that's not safe for humans anymore.
