Why should we not throw cooking oil and fats down the drain?

Solution
Cooking oil and fats should not be disposed of off down the drains as these get harden and block pipes. They reduce the flow of water and result in stagnant water, which provides a breeding ground for mosquitoes and flies and spreads infectious diseases.
