Myopia is Genetic - Health

Myopic vision is genetic as well as Environmental - Health.
Myopia is a very odd condition. Shortsighted people can only focus at a close distance because their eyeballs have grown too large. It is not so much an illness as a consequence of growing.
It is a genetic problem. About 90 per cent of East Asians suffer from myopia. This compares to 25 per cent of Australians. Too much reading indoors is a causative factor. The more years one partakes in education the higher the probability that shortsightedness will occur. Spending time outdoors where it is necessary to focus on things at a distance seems to be preempt the ailment.

Getting glasses does treat the condition. However, it can lead to problems in the future. There is a higher possibility of going blind. Detached retinas and glaucoma lead up to this.

The age of technology has not been a factor in myopia. Yes, there is a lot of reading on tablets which is detrimental. Whether reading a book or looking at a screen, there is no difference.

El Niño Threatens but La Niña Persists in Australia

While a new very strong El Niño is on the way, fears of continuing La Niña are real as well. Although Australia is known as a drought country, severe floods are damaging. This is because the continent is flat with a few mountains in the east of the country.
If the El Niño does not arrive flooding will continue. Furthermore, the drought in the US will cause further damage to their economy. The odd thing at the moment is that Australia has drought inland with flooding along the coast. This isn't s normal state of affairs. It could be due to global warning.

We have had a very long intermediate period where La Niña persists and El Niño threatens. Research shows that La Niña will return every 13 years instead of 23 years. It seems to Australians that La Niña has been here for ever with the long intermediate period persisting. There are extreme El Niño and La Niña though. And it is these that do the most damage economically and socially.

New Type of Flu From the Middle East

Generally, people do not keep up with the latest infectious diseases that could come their way. We all know about the Asian flu because it has been around for a while. However, there is little fear involved because many believe that they will not catch it.

Last year a new disease appeared called Middle Eastern Respiratory Syndrome (MERS). It killed more than half of the 79 people infected. In the serious 1957-1958 Asian Flu outbreak the death rate was 0.13 per cent.

While MERS is still present, the number of new cases has held steady. There is a worry that the disease could suddenly become highly contagious. It is not yet known whether the virus is spread by human contact or it has an animal source. The number of cases did rise during the Muslim hajj to Mecca.

The World Health Organization (WHO) is in an emergency sitting at present considering whether to declare the coronavirus a public health emergency. An emergency would allow travel restrictions to be put in place. Pilgrims may deem to ignore this and travel anyway, putting their faith in God. The Saudi government is not keen to stop Muslims attending the hajj. Countries cannot be forced to implement restrictions.

Australia's Economy Would "Stop" if Oil Imports Ceased

Some countries are moving toward other fuels such as coal gas. However, public opinion about it polluting the environment could bring an end to the trend of companies running roughshod over properties belonging to others. The search is driven by potential profit not for any long-term goal.

People are complacent. Australia is dependent on fuel from mainly Middle Eastern countries. If a major conflagration occurred there the Australian economy would come to a standstill in a matter of weeks. Rationing would have to be introduced immediately. Health and food would be the main priorities. Distribution would be hit hard as it uses most of the oil imported, apart from private use of motor vehicles.

Australia does not keep an oil reserve. Even though some countries have reserves. It would put off the economic hit for a few months. What is shocking is that even dried food in this country would last only nine days.

Using solar power for transport is not possible. If such a scenario did happen there would be a quick move to other resources like using sunlight to turn algae into a usable oil substitute. It has been calculated that algae would produce a minimum of 60 tonnes of oil from each hectare of pond surface. Streamlined systems could increase yield to over 600 tonnes.

At the moment there is no need to "manufacture" oil from algae. Natural oil remains the cheapest form of energy. Many universities are working on algae. Like everything else in this world new opportunities are only taken when it becomes necessary. Personally, I believe that there are solutions to a cut in oil supplies. Obviously there would be a world economic downturn, but Man has survived due to adaptation to changing environments. An oil crisis would be no different.

Man Caught Deep Ocean Fish 42,000 Years Ago

Our ancestors not only fished rivers and the coastline. They caught marine food in the deep ocean. It is known that people travelled across oceans 50,000 years ago. However, proof that they could catch fish in the deep sea went back only 12,000 years.

New evidence shows that Man ate fish from the ocean further back than 12,000 years. In caves on the island of East Timor remains of tuna and other large fish have been found.

East Timor was "out of bounds" for paleontologists until recently because of the ongoing troubles with Indonesia. Information on ancient Man is changing scientific knowledge about our ancestors. Bone fish hooks dating back 42,000 years have been found there.

The diet of early Timorese was varied. It included birds, rodents, bats, snakes turtles and fish. Few large animals lived there. Half of the fish found were tuna, a fast moving fish that would have taken great skill to catch. Using nets was the only way, so they had an advanced culture.
