The first step is to recognise what the consequences of overpopulation are . Only by doing this can we find an appropriate solution. Perhaps its most important effect is the increased rate at which we are consuming the Earth’s resources such as oil. To combat this, governments need to do more research on alternative and renewable energy supplies so that we do not use up all the oil reserves. Another negative effect of overpopulation is how some countries suffer from a lack of basic necessities such as food. Here, an answer could be greater international co-operation so that countries with a food surplus donate what they do not need to the less fortunate countries.
