The graph shows the predicted impact of various factors on the biodiversity of the Mediterranean Sea in the next 10 years. In this context, we need to understand the effects of two specific factors: hunting and the introduction of new plant or animal species.
If the government introduces laws prohibiting hunting, it would somewhat reduce the impact hunting would have on the biodiversity. This means that the negative effects of hunting on the biodiversity of the Mediterranean Sea would be lessened. Hunting, in this case, refers to the activity of killing or capturing animals for sport or food.
Similarly, if laws prohibiting the introduction of new plant or animal species within the country are passed, it will curb the effect of introducing new species on the sea's biodiversity. This means that the negative impact of introducing new species into the Mediterranean Sea would be reduced.
