Explain the effects of technology, birth rate, and life expectancy on population growth, and predict the challenges that countries may face as a result.

Technology, birth rate, and life expectancy has an effect on population growth in this manner;
Technology, as it progresses, can both harm people and help them.We will not be talking about harmful things ( for example: chemicals, nuclear weapons, wars, etc.) In helpful technology, it will be able to help people survive longer, increasing life expectancy and health rates. Things such as X-rays, medication, etc help people get better, find out new diseases and help save lives.
As people survive and life becomes easier, birth rate may increase, because more and more people are ready to have kids because of the knowledge that they may survive longer.
Some challenges for countries include:
Because of technological inventions, countries will have to pay for experiments and the cure, and other things. They will also have to pay wages,and have help run the hospitals by giving them funds and other necessary things. This will put a strain on the economy, but will allow their population to be safer

hope this helps
