SIR DAVID Attenborough has warned that polar bears could go extinct and ANOTHER major pandemic could hit if we don’t tackle climate change.
Writing in his new book, A Life on Our Planet, Sir Attenborough predicts a lifetime of floods, drought and the ocean turning to acid if the planet isn’t saved.
For those born today, the natural historian predicts a number of likely terrifying scenarios that the next generation could face.
In the decade beginning in 2030, after years of deforestation and the illegal burning in the Amazon basin, the world’s biggest rainforest could be reduced by 75 per cent.
“Reduced rainfall would cause water shortages in cities and droughts in the farmlands created by the deforestation. Food production would be radically affected,” Sir Attenborough wrote.
“The biodiversity loss would be catastrophic.
“Species that may have given us drugs, new foodstuffs and industrial applications may be gone.”
With global warming driving up the Earth's temperature, the thaws in the Arctic are starting earlier and the freezes are coming later.
It is quite possible that one year, the summer would be just that little bit longer, and the cubs born that year will be so small that they cannot survive their first polar winter.
This means that the polar bear, who relies on the northern sea ice to hunt seals, will begin to die off.
Sir Attenborough wrote: "As the ice-free period lengthened, scientists detected a worrying trend.
"Pregnant females, drained of their reserves, were now giving birth to smaller cubs.
“It is quite possible that one year, the summer would be just that little bit longer, and the cubs born that year will be so small that they cannot survive their first polar winter.
“That whole population of polar bears would then crash.”
With climate change continuing into the 2050s, the entire ocean would become totally acidic as a result of “carbon dioxide forming carbonic acid to trigger a calamitous decline.”
The middle of the 2050s would be the end for the remaining commercial fisheries and fish farming around the world.
Sir Attenborough predicts that vast crop failure will strike in the 2080s which will bring another pandemic.
Global food production will hit a crisis point after centuries of intensive agriculture adding too much fertiliser to the soil rendering it exhausted and lifeless.
The lack of food will also be made worse with the emergence of another pandemic.
“We are only just beginning to understand that there is an association between the rise of emergent viruses and the planet’s demise.
“The more we continue fracturing the wild with deforestation, the expansion of farmland and the activities of the illegal wildlife trade, the more likely it is that another pandemic would arise.”
But Sir Attenborough claims that all of the solutions are “within our grasp” and there are a number of “steps we can take and goals we must achieve to avert the coming catastrophe.”
