Dramatic changes to sea algae could herald devastation for human life:

Huge changes in the make-up of North Sea and North Atlantic Ocean algae in the space of five years could have harmful knock-on effects for human health and the rest of the food chain, research from Welsh scientists has revealed.

The changes seen in algal blooms – shifting from dinoflagellate to diatom algaes – could mean a build-up of toxins on feeder organisms.

Professor Graeme Hays, from Swansea’s Department of Biosciences in the College of Science, and an author in the study, said: “Imagine looking at your garden one morning and finding that the grass had suddenly been replaced by bushes. This may sound far-fetched, but we have found changes of this magnitude in the biology of the North Atlantic, with a dramatic switch in the prevalence of dinoflagellates to diatoms – two groups which include many of the microscopic planktonic plants forming the base of the ocean’s food chain.”

Animal-Related Diseases Concern Scientists

Health researchers and wildlife biologists say the number of infectious diseases that have jumped the boundary from animals to humans and between animal species is on the rise.

Scientists believe the increase may be a result of more frequent contact between humans and wild animals, as well as the growing trade in wild animals, both legal and illegal.
