The cumulative effect of what humans are doing to the oceans, are far worse than we had individually realised.
These “accelerated” changes include melting of the Greenland and Antarctic ice sheets, sea level rise, and release of methane trapped in the sea bed. Causing extreme weather everywhere
Some species are already fished way beyond their limits – and may also be affected by other threats
“So if you look at almost everything, whether it’s fisheries in temperate zones or coral reefs or Arctic sea ice, all of this is changing our environments.
Some pollutants, for example, stick to the surfaces of tiny plastic particles that are now found in the ocean bed.
This increases the amounts of these pollutants that are consumed by bottom-feeding fish then by people?
In a wider sense, ocean acidification, warming, local pollution and overfishing are acting together to increase the threat to coral reefs – so much so that three-quarters of the world’s coral reefs are now at risk.
Al-Jahiz wrote and predicted this almost two thousand years ago in his book.
“Animals engage in a struggle for existence; for resources, to avoid being eaten and to breed. Environmental factors influence organisms to develop new characteristics to ensure survival, thus transforming into new species. Animals that survive to breed can pass on their successful characteristics to offspring.”
Darwin wrote that things evolved by natural selection and latter in his work used the phrase survival of the fittest. That is the cause of the environmental changes of today.
If you look closely at Al-Jahiz claim he stresses environmental factors and Darwin does not.
What does Biology teach us today?
Over 99% of life is extinct no tree of life that Darwin called it just a tree of death.
Today just a few branches remain on that tree. Nothing is selected, no survival of the fittest. The ones who survive are the ones who can adapt best to new environments.
Today we are changing our environment and have no knowledge of what the consequence will be for man. We do know many other forms of life are going extinct has a consequence.
We are turning our blue planet red.
We are at the same point as the Dinosaurs were after the Asteroid hit.
