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.

While legalizaiton has benefits, a new study suggests it may have one big drawback.
- A new study finds that rates of marijuana use and addiction have gone up in states that have recently legalized the drug.
- The problem was most severe for those over age of 26, with cases of addiction rising by a third.
- The findings complicate the debate around legalization.
A new paper suggests that the mysterious X17 subatomic particle is indicative of a fifth force of nature.
- In 2016, observations from Hungarian researchers suggested the existence of an unknown type of subatomic particle.
- Subsequent analyses suggested that this particle was a new type of boson, the existence of which could help explain dark matter and other phenomena in the universe.
- A new paper from the same team of researchers is currently awaiting peer review.
The bill would effectively legalize marijuana at the federal level, while allowing states to draft their own laws.
- The bill aims to decriminalize marijuana and expunge federal convictions, among other provisions.
- To become law, it still has to pass through the Republican-controlled Senate.
- A majority of Americans support legalizing recreational marijuana, according to a recent Pew survey.
