Question

What are the good and bad activities of the biosphere?

Answer 1

Hint: The biosphere is the layer of the planet Earth where life occurs, (from Greek bios = life, sphaira, sphere). It is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.

Complete solution:
Few activities good for biosphere are:
a. Plant trees as they purify the air, and capture the sun’s energy.
b. Collect rainwater and reduce the use of plastic items, as it creates pollution.
c. Bring reusable cloth bags while shopping.
d. Use public transport instead of private vehicles.
e. Harvest rain-water to use in summers.
f. Segregate decomposable and non-biodegradable waste.
g. Harness solar, wind and hydro energy whenever possible.
h. Keep fans and lights off when not in use.
Few activities that are bad for the biosphere are:
a. Driving vehicles even for a short distance.
b. Cutting trees for selfish needs, like for wood for furniture purposes.
c. Using chemical fertilizers that causes soil and water pollution.
d. Throwing wastes on-road and not in a dustbin.
e. Keep the tap running, while brushing, that causes wastage of water.
f. Burning of coal and fossil fuels cause air pollution, which in turn cause acid rain.
g. Using air conditioners that have CFCs which cause harm to the ozone layer.
h. Overexploitation, like overfishing, harms aquatic life.

Note: Biosphere consists of the lithosphere, atmosphere and hydrosphere. The lithosphere is the terrestrial region, hydrosphere refers to the aquatic region and atmosphere refers to the gaseous envelope surrounding the Earth.
