Why failing to preserve biodiversity is a profound disrespect
Here are just two of the practical and philosophical crises surrounding biodiversity breakdown.
SUSAN HOCKFIELD: So there's a lot of news now about decreasing biodiversity. Nature has been reinventing itself for, what is it, almost five billion years, and producing all manner of different kinds of animals and plants, viruses, and bacteria. We worry -- I worry -- that we're going to lose basically our bank account. And let me give you an example. Developing better food products is incredibly important. To feed a population of over 9.7 billion, we're going to have to double the productivity of our crops. Now we've done that before through various kinds of technology, better farming machinery, but a lot of the improvements come from tapping into the biodiversity of plants in the wild.
So if we want to develop crops that are drought resistant or pest resistant, we can use our brains to try and figure out which individual genes we could change around. But that's a very hard way to do it. An easier way to do it -- and it's a strategy that farmers have used for thousands of years -- is to find a related crop that has the desired characteristic -- drought resistance or pest resistance -- and crossbreed it with a crop that we like, that makes the kind of corn that's sweet with a lot of kernels on the cob or a tomato that has particularly brilliant flavor and cooks up well, but maybe is quite sensitive to frost. So to breed our perfect tomato plant to a wild plant that has characteristics we might want is one way, a very important way, that we've improved the crops that we grow. So a loss of biodiversity would limit the ways we can use the biodiversity to make our world better.
But I actually have a deeper philosophical worry. We don't know where the biodiversity that we currently have is heading. We don't know what kinds of plants or animals are in process. And it seems to me that it's an enormous disrespect for the great gifts that we have gotten to not try to preserve, as much as we can, the organisms that have struggled their way into existence today.
- A loss of biodiversity limits the ways we can use biodiversity to make our world better. Hockfield reminds us that biodiversity is a "bank account" of natural assistance.
- For example, it is key in producing better crops to feed growing populations. How will we double food productivity (which we must do to survive) when we lose the wild plants we crossbreed agricultural crops with?
- There is much more to lose than this bank account, however. It is a deep philosophical dilemma that humans have and will continue to wipe out organisms that have struggled their way into existence over the course of 5 billion years.

TheTrueSize.com offers hours of fun while you stretch and shrink countries and states all over the globe.
- Our world maps lie to us: North America and Europe aren't really that big and Africa really is much bigger.
- It's all the fault of Mercator: even if the man himself wasn't necessarily Eurocentric, his projection is.
- This interactive map tool reveals countries' true sizes without having to resort to the Peters projection.
Hundreds more are documented in Robert Macfarlane's Landmarks.
- In Landmarks, Robert Macfarlane revives hundreds of nearly-forgotten words to remind us of our relationship with nature.
- New dictionaries are deleting nature words while adding technology terms, which Macfarlane states further separates us from the environment.
- The words we speak shape the reality we understand, making it essential to aptly describe what is happening on the planet.
