From Wikipedia article titled "Externality":There are a number of potential means of improving overall social utility when externalities are involved. The market-driven approach to correcting externalities is to "internalize" third party costs and benefits, for example, by requiring a polluter to repair any damage caused. But, in many cases internalizing costs or benefits is not feasible, especially if the true monetary values cannot be determined.

No, it could be a sign of strength if the social norms were slightly odd. For example, the negative social norm in the UK of passing people in an empty street - most will walk past quickly and not acknowledge each other. Saying "hello" or "good morning" in this situation is not the social norm, however it's probably more polite and it's definitely not a sign of weakness.
Being smart is, of course, not a bad thing at all. However, "nerd" has become a stereotype for the person who does nothing but study and has no social life.
Athletics are a positive influence with students in middle school because it gives them a social group and a healthy activity to identify with and belong to. Anything that gives positive reinforcement and the opportunity for physical activity is extremely beneficial.
A more definitive answer to an example of a negative externality is as follows. When the production of a product generates pollution, there are costs that fall onto society in addition to those of the producer. This may have the social cost exceed the private cost of production. This brings us to the term of total surplus. In this example, total surplus is the value to consumers minus the true social cost. With this said, it boils down to this: when the benefit to society is less than the weight of the externality, it is a sure negative.
In the presence of an externality (positive or negative), individual economic actors produce a socially inefficient amount of a good (since they do not include social gains or costs in their calculations). Thus, in general, when there is a Negative externality, firms are overproducing a good with a social cost and thus the optimal equilibrium occurs at decreased production. Positive externality, firms are underproducing a good with a social benefit and thus the optimal equilibrium occurs at increased production.
An externality (an action that has an uncompensated effect on someone else) causes the market equilibrium to fail to maximize the total benefit to a society. The government must then influence the behaviour of buyers and sellers through Pigovian taxes (a tax that equals the cost on the bystanders) and subsidies. A negative externality has a negative effect on bystanders causing the cost to society (social cost) to be greater than the private cost to the suppliers. The social cost curve lies above the private cost curve and the difference between the two is the cost of the good on the bystanders. The government uses a Pigovian tax to influence sellers to produce the good at the social cost, causing the price of the good to increase and therefore the quantity demanded to decrease. The intersection between the social cost curve and the demand curve becomes the optimum quantity. A positive externality has a positive effect on bystanders causing the value to society (social value) to be greater than the private demand of the buyers. The social value curve lies above the private value (demand) curve and the difference between the two is the value of the good on the bystanders. The government subsidizes sellers to influence sellers to produce more of the good at the quantity where the social value curve intersects the private cost (supply) curve. This becomes the optimum quantity.
Negative externalities lead markets to produce a larger quantiy than is socially desirable. Positive externatlities lead markets to porduce a smaller quantity than is social desirable. To remedy the problem, the government can internalize the externality by taxing goods that have negative externalities and susidizing good that have positive externalities.

Governments have the ability to compensate and decrease externalities such as marginal social and environmental costs by regulatory, taxation, and punitive fine regimes. Thus, governments can use revenue and legal mechanisms to increase the cost of such externality causes and by doing do decrease their incidence.
Promoting renewable energy sources to address climate change has social benefits such as reducing air pollution, creating green jobs, and improving public health. By transitioning to cleaner energy sources, we can mitigate the impacts of climate change and create a positive externality for the environment, benefiting society as a whole.
