Monoculture and its impact on the Environment
Growing a single crop species over a large area or farm is called intensive farming or monoculture. Earlier practices of mixed cropping caused problems in crop management, like harvesting, etc. Uniformity in plant height adds beauty to our fields and makes the application of agrochemicals easy. It also saves time and energy in segregating grains in threshing.
Development of science in 2022
The year 2022 has remained a year of big scientific achievements. In it, the discovery of probability of wormhole and Dart campaign of NASA in space science have been remarkable.
