of species in an ecosystem or on the entire Earth. Biodiversity
gets used as a measure of the health of biological systems, and to
see if there is a danger that too many species become extinct.

of human species by providing food, fuel, shelter, medicines and
other resources to mankind.

raising alarmingly.

city .This resulted in entry of water into the
houses and blockage of roads.

have released water from four lakes near Chennai, leading to
inundation of areas around it.

and Madurantakam lakes and officials have cautioned people living
in low-lying areas. This could flood localities such as Porur,

evacuated from low-lying areas and have been given shelter in

wade through knee deep water and it is getting worse with more
rainfall forecast," said Ramesh. Some even took to social media to
express their displeasure with one saying, "Even though the rains
