Topic: What is sustainability and why should we care about it anyway?

Reflection:)

First of all, I searched about 'sustainability'.

The term “sustainability” is often thrown around in public discourse, especially in discussion about the environment. However, not everyone is certain about the meaning of sustainability, and different people think about it in different ways. The etymology of the word “sustainable” incorporates Latin words meaning to hold up from below. Most dictionaries define “sustainability” as the ability to continue an action without the risk of failure or collapse. A strong building is sustainable, because it is able to hold up a load indefinitely. Clear cutting is not sustainable, because it strips an area of trees which cannot be replaced, and exposes the environment to additional repercussions, because the ground is exposed.

I was note taking this.

people care about somethig, lf.

-They feel it is of consequence.

-They feel it affects them.

-They believe they can do something about it.

Some energy fundamentals.

-Hubbert depletion curve

-Exponential growth

-Rates of increase are really, exponential

-Boubling time = 70/12

Also, I saw the graph of the limits to growth such as pollution, food, and population.

we can understand easily through the big pictures.

The presentation showed a lot of picture instead of words.

Notes on the topic:)

repercussions- an unpleasant effect or result of something you do

hold up- to cause a delay
