Assertion: Tropical rain forests are disappearing fast from developing countries such as India.
Reason: No value is attached to these forests because these are poor in biodiversity.

Assertion (A) is true but Reason (R) is not correct.

Tropical rain forests:

Tropical forests are closed-canopy forests growing within 28 degrees north or south of the equator.

They are very wet places, receiving more than 200 cm of rainfall per year, either seasonally or throughout the year.

Temperatures are uniformly high - between 20^°C and 35^°C.

Such forests are found in Asia, Australia, Africa, South America, Central America, Mexico and many of the Pacific Islands.

Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. Hence Reason is false.
