1. The water crisis
The global water crisis is a top issue in the world this century. Countries that have access to clean water are depleting resources very quickly while other less developed countries may not even have access to water in their communities. I believe countries like the US need to be more conservative with their water consumption before we run out of a potable supply. A short term solution to minimizing water consumption could be developing more efficient toilets and showers to save water per every toilet flush and shower.
2. Climate change and extreme weather events
Climate change has began to noticeably affect our world. Throughout the planet there have been incidences of pollution, abnormal temperature patterns, and extreme weather events. All three of these problems can have monumental impacts on agriculture, life on earth, and even the world economy. Climate change is an almost irreversible process given our current emission levels so I think that the "Green Movement" or increased technology are the only plausible solutions to the global climate change problem.
3. Radical anti-western terrorist groups
From a national security standpoint, terrorist organizations are probably the world's biggest problem. Terrorists can usually not be linked back to an entire country. Rather, they all share a radical mindset and act in the name of God. This makes it difficult to combat this problem that the world faces but, nonetheless, I would implement much more stringent screening on legal immigration to the US, especially from countries in the middle east.
4. Nuclear Weapons
Countries such as Iran, Russia, and even the US have nuclear weapon programs that need a lot of adjustment. A nuclear strike could wipe out entire cities and alter the earth's atmosphere for centuries. I believe nuclear warfare should never be used on earth because the environmental impacts are too devastating. I would make a global treaty banning the use of nuclear weapons.
5. Surveillance
With the increase of technology, more developed countries are able to collect data on their citizens and possibly even watch over their online or moblie communications. I firmly stand against surveillance of citizens online and over the phone so a solution could be to create legislation monitoring gonvernment surveillance
6. Food crises
In many parts of the world, there is still not enough food to sustain people. This sometimes even results in famine. Food shortages are a huge problem in less developed countries. I believe that if prominent social figures raised money and awareness about these issues, a little fundraising from the wealthy could go a long way in feeding hungry mouths around the world.
7. Fuel
Oil has been our primary fuel source for centuries but it is harmful to the environment and a limited resource. Alternate efficient fuel sources must be developed in order to fix this problem facing the world. Using solar and electrical energy will be more environmentally friendly and sustainable.
8. Species extinction
Humans are increasingly taking up other species territory. Sometimes this can cause those species to become endangered or even extinct. I believe there needs to be legislation to monitor and restrict more species extinction.
9. Internet
The internet is a great resource for people around the world. The amount of users is growing exponentially. However, I feel the internet is causing a major problem around the world. We are way too dependent on the internet in business and in daily life. If the internet were to crash (cyber-warfare), we would be in for a huge problem.
10. Political tension
Political unrest is everywhere. I believe that democratic governments must get together and fit communism and political unrest round the world.
