#climatechange #guymcpherson #globalwarming In this video I interview Guy McPherson a biologist and professor emeritus of the University of Arizona. He currently resides on a homestead in Belize. Dr. Mcpherson believes that the biggest threat facing mankind is global warming, that the threat is being downplayed and that its long past the point of being resolved as a phenomenon called ‘runaway climate change’ has already been put in motion.

Using nuclear science to improve animal breeding

Animals, so important for food security – they provide us with milk, with eggs, with meat. But as global population growth has accelerated, so has the demand for animal produce – putting a strain on both farmers and the environment. Simply raising more animals is not an option; it would put even greater pressure on an already strained environment. The solution lies in increasing the productivity of those animals. This is usually done by selecting and breeding superior animals; but this is a slow process, it can take several years to determine their breeding potential. Now, with advances in genomics, it has become possible to estimate the breeding potential of an animal on the day of its birth, simply by looking at its DNA – or genome map. Just watch the animation and you will see how.

Using nuclear science in marker-assisted plant breeding

Imagine you must identify a glass of seawater among a hundred glasses of drinking water merely by looking at them. Almost impossible! But what if the glass with the seawater had a small red dot – a marker – on it? You would solve the riddle in no time. Finding this marker is exactly what new developments in science now allow plant breeders to do. Plant breeders improve crops by using natural or artificially-induced genetic variation to develop new traits. But they face enormous difficulties when integrating these improved traits into the varieties that farmers prefer; it’s a process that requires a lengthy and cumbersome series of crosses, followed by testing and confirming at each step. But now, they can use modern DNA sequencing techniques to determine the plants’ entire genetic makeup. Just watch the animation and you will see how.
