ARE WE FALLING BEHIND IN EVOLUTION?

ARE WE FALLING BEHIND IN EVOLUTION

From the beginning of life on Earth all species have evolved through the process of natural selection. With natural selection only the strongest of each species survived to reproduce and pass on their unique genetics to there young.  If the  gene combination between the male and female was not favorable the offspring would not survive, but if it was good, a healthy, strong, disease resistant offspring would survive to reproduce again.  Over time the species would gradually evolve.  For hundreds of thousands of years humans have been no exception, until now.

How will the rapid and continuing advances in Medical Science over the last 100 years effect the genetics of our future generations?

Is medical science making us sicker?

Out of all the people close to you, take a moment to think about how many would not still be alive if not for recent advances in medical science such as asthma treatments, cancer treatments, antibiotics, surgeries etc.? The fact is medical science has saved a dramatic amount of lives but of all the people saved it has not done anything to change the genetics that caused the problems in the first place.  Are weak and disease prone genes being passed on to our children causing them to be sicker and develop even more medical problems?  Are we slowly becoming weaker as a population?  Elementary schools have already shown a dramatic increase in the average number of students off sick on any given day as compared to 25 years ago.  Is this just the beginning of what will be an ever increasing trend in the future?

Some might argue that there is no problem, people are living well into their 80’s now, but when you think about it people in their 80’s now were born back in the 1930’s. Their parents would have been born in the late 1800’s to early 1900’s back when Medical science was not nearly as advanced as it is now and didn’t have such a profound effect on natural selection.  Being born with good healthy genes and having the benefits of modern medicine at a later age, these people could be on average one of the healthiest and longest living generations ever.  Will we soon start seeing a decline in the average life expectancy of future generations?

Is Medical Science keeping up?  We now have antibiotic resistant bacteria, superbugs, SARS, and most recently Ebola that has left scientists scrambling to find a cure.  As bacteria and viruses continue to evolve and we become weaker what’s next?  Will medical Science be able to keep up with our ever increasing genetic shortfalls?   At what costs?

In some third world countries where modern medicine is not widely available the process of natural selection still continues.  Are these people slowly becoming genetically stronger then the people in developed countries? If there was a new major global disease outbreak that science could not find a cure for quick enough are they more likely to survive?

Research into genetics and DNA is making dramatic differences in our lives today. We now have drought resistant crops, disease resistant livestock even apples that don’t go brown but when it comes to humans there is currently a moral barrier.  Some people believe experimenting and altering genes and DNA in humans is crossing the line and too much like playing god.  Have we already crossed the line? Does this line even exist or is it just our way of dealing with the current way we think?   Aside from going back to natural selection is gene and DNA altering the only way for us to continue to survive and evolve?

DOES EARTH HAVE CANCER? / SAVING THE ENVIRONMENT

edited credit photo courtesy of NASA - Copy.jpgCancer can not survive without a host.  In small numbers it goes basically undetected but as its numbers increase the effects begin to break down various systems of the host.  Eventually the cancer becomes so large in numbers the host can no longer survive and dies, and with it so does the cancer.

Are we the cancer of the Earth?

In the last 50 years the world population has more then doubled from 3.3 billion to 7.3 billion people.  At our current population the environment is already noticeably stressed.  Estimates show that the world population could reach 9 billion by 2050.  Even with breakthroughs in science how many people can the earth support?   10 billion?  15 billion?  500 billion?  At what point will we realize we cannot go on the way we are and how badly damaged will the environment be by then?  Will it be too late?

Cancer Cells have no idea that there ever increasing numbers will eventually kill there host, along with them.

Are we smarter then a cancer cell?

Evidence of how fast the population is growing is not hard to find. In Toronto Canada there are so many new condos going up it’s not uncommon to find 3 construction cranes close together. Solutions to Toronto Traffic Part 2.jpgDoes Earth have cancer 2.jpg

The city of Bradford 65km to the north of Toronto has seen hundreds of acres of new housing built over the last 10 years, the edge of which can be seen in the distance of this photo. In the next 2 years housing will cover all of the empty field shown.Does Earth have cancer 4.jpg

Tapping the brakes on world population

Raising a child is one of the greatest and most fulfilling basic things in life and no one should be denied the experience, however our current mind set that large families our enviable has to change and changing our mind set and values takes time.  If the average family had only 1 or 2 children the world population would begin to decline. Even if the average amount of children per family were 2,  the population would no longer increase.  No one should be told how many children they are allowed to have but through education and government incentives on a national and global level people need to be encouraged to have smaller families.  Our increasing population is by far the single greatest threat to ourselves and the environment, it is also the easiest thing to fix.

Currently in Canada the government is still encouraging large families and offers thousands of dollars in tax savings for every child you have, in effect paying Canadians to have more children. What would happen if the government announced over the next ten years these tax savings would not change for the first child, be reduced by one half for the second child and nothing for any additional children? Would Canadians reconsider how many children they are going to have?  If not, what if the money the government saved from this was given as a form of tax credit to the families that just had one child or no children?  It’s hard to say right now what and how much it would take in government incentives to get the average family size down to a sustainable level and no doubt incentives would vary between countries.  Could there be other benefits to this kind of government policy?  Would financial incentives to have less children also possible reduce the number of unwanted or abused children?  Would having less children result in better care for the ones we have?   The sooner we start, the more time we have to learn and adjust and the easier the transition will be.

Governments also need to do more when it comes to contraception. Young people need to be educated before the age they become sexually active.  Affordable methods of contraception need to be made available to everyone and more research into new reliable methods needs to be done. The number of unplanned or unwanted pregnancies needs to be reduced as close to 0 as possible.

Not only do we need time to adjust to the idea of smaller families, what about the economy? How would a slowing population growth effect the economy?  Doe’s  our current economy rely on the pyramid system requiring more and more people every year to keep going?  By a slow and gradual reduction in population growth we can hopefully avoid any major economic disasters.

We can no longer think that we can sit back and as long as we recycle, conserve energy, use green products and green companies that everything will be  fine.  The fact is unless we can start to control our population now all other efforts are for nothing.  In the 5 minutes  it took you to read this article there are over 700 more people on earth. By this time tomorrow there will be another 200,000.
