Para maiwasan na makagat ng lamok na aedes aegypti (uri ng lamok na nagkakalat ng Dengue Fever), laging magpahid ng mosquito repellant lotion. At kailangan din iwasan ang mga stagnant water o huwag magimbak ng mga tubig na maaring bahayan ng mga lamok.

Ozone layer can be protected by minimizing pollution.

Gases like CFCs (chlorofluorocarbons) and BFCs (bromofluorocarbons) contribute to the degradation of the Ozone Layer by increasing the amount of chlorine and bromine in the atmosphere. Along with NO and N2O (nitric and nitrous oxide), and OH (hydroxyl), these free-radical catalysts destroy ozone in the stratosphere.

Minimising the use of CFCs in manufacturing and propellants is an ongoing effort in the mitigation of man-made damage to the ozone layer. Using more reactive hydrochlorofluorocarbons (HCFCs), the hope is that these chemical compounds will not survive the journey to the stratosphere, thereby reducing the damage they can do- however, as they are still capable of causing damage, their use is being reduced too.

The issue with CFCs is that they can survive for decades in the atmosphere, and remain unchanged by their interaction with ozone. Even if we stop all use of CFCs, it may still take centuries for the ozone layer to return to normal. However, the rate at which the ozone layer is being depleted has slowed significantly in recent years.

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, and other similar compounds are primarily responsible for ozone layer depletion. These substances release chlorine and bromine compounds when they break down in the atmosphere, which then react with ozone molecules, leading to the depletion of the ozone layer.
