what is green house effect also explain advantage or disadvantage of green house effect

hii friend here is your answer...
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions
BENEFITS
1. The greenhouse effect helps to maintain a certain temperature level on Earth’s surface, making it habitable for the living beings . Thanks to the greenhouse gases, the earth is warm enough to sustain life. It has been estimated that without the presence of atmosphere and gases, the temeparture of the Earth would have been somewhere around -18 degree centigrade, quite unbearable.
2. The greenhouse gases help block the harmful solar radiation from reaching planet’s surface. These gases work like a filter and bounce back most of the unwanted and damaging energy into space.
3. Ozone, which is one of the crucial greenhouse gases, absorbs the harmful ultra-violet (UV) rays of the sun. If there wasn’t any Ozone layer in our atmosphere, the UV rays could reach the surface directly and affect the life on earth on a massive scale causing cancers, sunburn, damaging immune system and eyes.
Ozone has already depleted 4% since 1970, creating chances for an ozone hole.
4..For millennia, the greenhouse effect has helped the planet keep a perfect balance between the amount of absorbed energy and the reflected energy
DISADVANTAGES
1. Global warming: As mentioned previously, the increasing amount of greenhouse gases are causing a gradual rise in the earth’s temperature. As a result, the ice in the Polar Regions has started melting and resulting in massive climate changes.
2. Increased level of CO2: The concentration of CO2, which is one of the common greenhouse gases, is not only affecting the marine lives but are also disrupting the photosynthesis process of plants.
3. Rising water levels: Because of the greenhouse effect and global warming the water levels are rising and polar caps are threatening to melt, putting millions of lives in danger.
4.Loss of Flora and Fauna: The rapid increase in rise of temperature owing to Greenhouse gases is called as Global Warming. With Climate change caused by Greenhouse emissions induced Global warming, there are increasing chances of floods, droughts, and destruction of natural habitats, risking entire biotic life.
