We live in a day and age where, thanks to the internet, people can learn almost anything at anytime. The internet, in the present, is mostly used as a learning tool as well as a source of entertainment and global communication. The fact that people can now communicate so easily helps to make people more aware of problems worldwide including: pollution, famine, disease, destruction of natural resources, etc. Based on these facts, I believe that the younger generations should have, at least, a little more of a part in these issues.
It's not their fault that these problems exist in the first place. And since the generations that caused them are still around--for the most part--they should be mostly responsible for solving these problems. I will not deny that younger generations will be more able to fix it, since they'll be around longer to do so. I just think that the older generations--while they're still around--should be the ones resolving the world's problems.
