Please help. I don't get it. Thank you.

A force is a push or a pull upon an object which results from its interaction with another object. Forces result from interactions
Consider the propulsion of a fish through the water. A fish uses its fins to push water backwards. But a push on the water will only serve to accelerate the water. In turn, the water reacts by pushing the fish forwards, propelling the fish through the water. The size of the force on the water equals the size of the force on the fish; the direction of the force on the water (backwards) is opposite the direction of the force on the fish (forwards). For every action, there is an equal (in size) and opposite (in direction) reaction force. Action-reaction force pairs make it possible for fish to swim.
When the person uses force to propel himslef from the boat, it can cause him to fall.

His third law is that every action has an opposite and equal reaction. Like if you throw a ball against a wall, it will bounce back at you just as hard. Therefore, if you jump from the canoe, you are going to hit the riverbank with a certain amount of force. If you're not careful, you'll fall backwards from the force of your jump.
