Different kinds of pollution have harmed the environment as well as man's well-being. Air and water pollution particularly contribute to air and water-borne diseases and ill-health. Ozone layer depletion and global warming are other severe problems resulting from such degradation. Environmental crisis refers to a situation when an environment fails to perform its vital function of life sustenance. The environment becomes suitable as soon as the following happens: Resource extraction remains below the rate of resource generation. Environmental degradation is a major contributor to climate change. Deforestation, overfishing, and other unsustainable practices lead to the destruction of habitats, the release of greenhouse gasses, and the disruption of natural carbon sinks. Minimizing use or waste of non-renewable resources - including minimizing the consumption of fossil fuels and substituting with renewable sources where feasible. Also, minimizing the waste of scarce mineral resources (by reducing use, reusing, recycling, and reclaiming). Environmental conditions affect human health, well-being and other quality of life aspects, both directly, for instance through pollution, and indirectly, for example, by having an impact on property prices that could in turn affect an individual's economic prosperity. Deforestation resulting from economic development damages soil and makes areas more prone to drought. Economic growth leads to resource depletion and loss of biodiversity. This could harm future 'carrying capacity of ecological systems' for the economy. Environmental protection is aimed at maintaining a healthy natural environment. Sustainable development embraces environmental, social and economic objectives, to deliver long-term equitable growth which benefits current and future generations. Sustainable economic growth, achieving sustainable livelihood, living in harmony with nature and appropriate technology are important for sustainable development. Environmental Sustainability: It prevents nature from being used as an inexhaustible source of resources and ensures its protection and rational use. Socially, sustainable practices can help strengthen community bonds, improve quality of life and provide hope for a better future. Environmentally, sustainable practices can help protect natural resources, mitigate and adapt to climate change and promote biodiversity.
