Undoubtedly, the population growth is one of the most influential social issues in the recent years. As the earth's population rises, the changes in different aspects, environmental, global economic and political, affect our individual life.

No matter it concluded the outcome of overpopulation is a disputed subject or note, but it is a fact that more cities will continue to grow, waste and pollution will be on the rise, and natural resources will continue to be depleted.

Example of Effecting Factor
Here is an example of the effecting factors. The fishing industry is a good example to illustrates the effects that bring by the population growth.

Although it is a kind of an inexpensive fish, the market value has gone up, and tuna is even auctioned off to the highest bidder in seafood auctions. When a company buys this fish, it is then put into refrigerated containers and flown to different parts of the world. The repercussions put more strain on the tuna population as it becomes an even more desired delicacy. And it is predictable to see that the price of tuna will continue to rise. However, the difficulty of enforcing a global reduction of fishing tuna is that not all countries...
