To introduce new seeds, we could mine plant gene banks. To that idea we can add research that is underway now producing improved seeds. In three examples, the International Rice Research Institute has developed salt-tolerant rice and drought-resistant rice, and BioCassava Plus is working on a more nutritious cassava for sub-Saharan Africa.
Shop What is Overpopulation? Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation.
It is possible for a sparsely populated area to become densely populated if it is not able to sustain life. Growing advances in technology with each coming year has affected humanity in many ways.
One of these has been the ability to save lives and create better medical treatment for all. A direct result of this has been increased lifespan and the growth of the population. In the past fifty or so years, the growth of population has boomed and has turned into overpopulation.
In the history of our species, the birth and death rate have always been able to balance each and maintain a population growth rate that is sustainable.
Between the time of the plague and the 21st century, there was been hundreds and thousands of wars, natural calamities and man-made hazards. However, none of these have made a dent on the population.
Developing nations face the problem of overpopulation more than developed countries, but it affects most of the Earth as of now. When we are talking about overpopulation, we should first understand the causes of it. Causes of Overpopulation Decline in the Death Rate: At the root of overpopulation is the difference between the overall birth rate and death rate in populations.
If the number of children born each year equals the number of adults that die, then the population will stabilize. Talking about overpopulation shows that while there are many factors that can increase the death rate for short periods of time, the ones that increase the birth rate do so over a long period of time.
The discovery of agriculture by our ancestors was one factor that provided them with the ability to sustain their nutrition without hunting.
This created the first imbalance between the two rates.
Following this came the industrial revolution. Technological advancement was perhaps the biggest reason why the balance has been permanently disturbed.
Science was able to produce better means of producing food, which allowed families to feed more mouths. Medical science made many discoveries thanks to which they were able to defeat a whole range of diseases. Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines.
Combining the increase in food supply with fewer means of mortality tipped the balance and became the starting point of overpopulation. More Hands to Overcome Poverty: However, when talking about overpopulation we should understand that there is a psychological component as well.
For thousands of years, a very small part of the population had enough money to live in comfort. The rest faced poverty and would give birth to large families to make up for the high infant mortality rate.
Families that have been through poverty, natural disasters or are simply in need of more hands to work are a major factor for overpopulation. As compared to earlier times, most of these extra children survive and consume resources that are not sufficient in nature. Technological Advancement in Fertility Treatment: With latest technological advancement and more discoveries in medical science, it has become possible for couple who are unable to conceive to undergo fertility treatment methods and have their own babies.
Today there are effective medicines which can increases the chance of conception and lead to rise in birth rate. Moreover, due to modern techniques pregnancies today are far more safer. Many people prefer to move to developed countries like US, UK, Canada and Australia where best facilities are available in terms of medical, education, security and employment.What Are Some Overpopulation Causes and Solutions?
The causes of overpopulation in a given region may include good food production, improvement in public health, illiteracy, poverty and disease control or prevention. While some of these causes may seem positive, the effects of overpopulation.

view from brussels;. If population growth is unsustainable, are there humane ways to limit it? 1) Empower women. Studies show that women with access to reproductive health services find it easier to break out of poverty, while those who work are more likely to use birth control.
In order to reduce the adverse impacts of overpopulation, mitigation measures, such as spreading awareness and education about overpopulation, enacting birth control measures and regulations, and providing universal access to birth control devices and family planning, must be taken.
