Correct
- The ozone hole is the region over Antarctica with total ozone of 220 Dobson Units or lower.
The greenhouse effect is the problem caused by increased quantities of gases such as carbon dioxide in the air. These gases trap the heat from the sun, and cause a gradual rise in the temperature of the Earth’s atmosphere.
Ultraviolet (UV) is electromagnetic radiation with wavelength. The sun emits three different types of UV radiation: UVA, UVB, and UVC.
Sustainable development is important as it saves the national budget, fulfills the need of people, conserves natural resources, helps in the coordination between the natural resources and people, and conserves natural resources for future generations.
Ecocentrism expands the moral community (and ethics) from being just about ourselves. It means we are not concerned only with humanity; we extend respect and care to all life, and indeed to terrestrial and aquatic ecosystems themselves.
