Why is biodiversity important?

596 viewsBiologyOther

Genuine question. I was talking to someone recently and they asked me this and while I had some answers (mentioned below), I didn’t have confidence in my answers.

I know climate change is a threat to biodiversity and that it’s important to preserve it but I was never told why biodiversity is important. Is it to keep ecosystems in check (I feel like this is probably one of the most important reasons)? Is it to just give humans a bunch of species to look at and appreciate? Is it to ensure that if the human population died, some forms of life would remain that would be fit for whatever catastrophe affected human populations and keep life going?

Is it all of these things? Any other reasons?

Thank you!

Think about bio diversity in food terms.

You need to eat a balanced diet, right. Fruits, vegetables, protein, carbs, etc.

Well, what if for example we were to lose alllll biodiversity and the only food left in the world was lettuce, a lot of it, but just lettuce… humans wouldn’t be able to nourish themselves with just lettuce because we need all the vitamins, minerals, fibers, proteins, carbs, etc to survive. We would then die off and cease to exist.

Biodiversity like this happens on all different levels of life forms from plants to animals to bacteria and humans, etc. but as each level crumbles, it affects all those around it that rely on that as well and so on.
