However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates: automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or upon express reinstatement by the Licensor. For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. Section 7 – Other Terms and Conditions. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.

Effects of global warming on respiratory diseases
Abstract
Background: Global warming is a consequence of air pollution resulting in climate change due to trapping of excess greenhouse gases in the earth's atmosphere that affects biodiversity and constitutes a serious health hazard, especially to the respiratory system. These greenhouse gases include carbon dioxide, water vapor, methane, ozone and nitrous oxide. They hold heat in the atmosphere thereby creating a greenhouse effect. The sources of these gases include human activities like industrial air pollution, burning of human waste, wood and forests, tobacco, fossil fuels like oil, natural gas and coal, deforestation and the release of chlorofluorocarbons (CFCs). Climate change brought about by global warming results in storms, drought, and floods which can be of immediate threat to life, the respiratory system being particularly vulnerable because of the background air pollution. Effects of global warming on the respiratory system include potentially increased incidence (and/or worsening/exacerbations) of the following: bronchial asthma and other allergic diseases, infection (pneumonia and tuberculosis), parasitic lung diseases, chronic obstructive pulmonary disease, hypersensitivity pneumonitis, lung cancer and sudden death.
Aim: To create awareness and increase enlightenment about the very important subject of global warming and the lung.
Methods: A literature search on global warming and respiratory diseases was carried out through the internet (Google, Medline) and locally. Data synthesis was carried out and synchronized under the following headings: introduction, effects of global warming on respiratory diseases, respiratory diseases, and recommendations.
Conclusion: There is urgent need for control measures to be taken to mitigate the effects of global warming on the respiratory system.
Keywords: Global warming, respiratory diseases
