Top 5 World Problems

ISIS
The threat of ISIS continues to grow as they target people from multiple countries. ISIS is trying to make a clear statement that they are not only targetting certain people. I feel that a practical solution would be to continue fighting against ISIS but to get every country involved. It seems that the US is the only major country fighting against ISIS and trying to destroy them when I feel all countries should be involved. 
Lack of drinking water in 3rd world countries
The amount of drinking water in 3rd world countries continues to diminish. With water being filled with chemicals and diseases, it increases the amount of unhealthy individuals in these countries. The UN or countries alone should begin donating water filters and clean water supplies to the third world countries to use to have drinking water that will not make them ill.
Global Warming
Global warming continues to become a problem where the ozone layer continues to deteriorate. A practical solution would be to implement products that tear apart the ozone layer to be banned or have a specific amount of usage per person. Also the companies that create these products should begin implementing tactics to create more environmentally friendly products.
Unemployment rate in America
Unemployment rates have gone down in America recently but they are still not at 0. Employment is a crucial part of American society and being able to thrive and have a good lifestyle. If more companies would create factories in America rather than oversees more Americans would have jobs for products that are being sold in America.
Low minimum wage in America
Minimum wage around America being around eight dollars an hour is ridiculous. In a society where prices for everyday items continues to rise, minimum wage should also rise. I know some of the presidential candidate have made statements about raising minimum wage to 15 dollars an hour, however I feel it is more realistic to slowly raise it that the national minimum wage must be at least 10 dollars an hour and then raise it from there yearly or biyearly.

Explanation
I believe that ISIS would be the most serious ranking of problem because ISIS is not affecting a single population, but rather the everyone. ISIS has attacked American's, Europeans, and British just to name a few. ISIS is an extreme issue that if it is not resolved will only continue to cause more problems for everyone. They are relentless and do not fear hurting individuals in crazy ways. 

The solution that would be the most-possible would be to solve the low minimum wage in America. As I discussed I felt that the government needed to slowly implement a higher minimum wage. If they immediately jumped the minimum wage to 15 dollars, people would get upset months later and be wanting more. If the government slowly increased the minimum wage people would be sufficiently happy about it and be able to learn how to manage and save the money.
