Question

please give me the speech of ENVIRONMENTAL DEGRADATION
urgently

Sandhya Ts · Answer

The natural environment, with all its ecosystem services,
comprises the entire basis for life on the planet Its value is
therefore impossible to quantify or even model The state of
environment has – at any given stage – effects on food
production through its role in water, nutrients, soils, climate and
weather as well as on insects that are important for pollination
and regulating infestations The state of ecosystems also influences
the abundance of pathogens, weeds and pests, all factors with a
direct bearing on the quality of available cropland, yields and
harvests
Environmental degradation due to unsustainable human
practices and activities now seriously endangers the entire
production platform of the planet
Land degradation and conversion of cropland for non-food
production including biofuels, cotton and others are major threats
that could reduce the available cropland by 8–20% by 2050
Species infestations of pathogens, weeds and insects, combined with
water scarcity from overuse and the melting of the Himalayas
glaciers, soil erosion and depletion as well as climate change may
reduce current yields by at least an additional 5–25% by
2050, in the absence of policy intervention These factors entail
only a portion of the environment covering direct effects The
indirect effects, including socio-economic responses, may be
considerably larger
THE ROLE OF THE ENVIRONMENT IN FOOD PRODUCTION
There is a strong link between the state of the environment
and food production, apart from the natural environment being the
entire platform upon which all life is based For crops, the state
of the environment directly influences soil nutrient availability,
water (ground and surface water for irrigation), climate and
weather (rainfall and growth season), availability of insects for
pollination, and not the least, the abundance and effects of
certain pests, such as pathogens, insects and weeds, which have
major impact on crops worldwide, particularly in Africa (Sanchez,
2002) Without these services, there would be no production,
Ecosystem services enhance agro-ecosystem resilience and sustain
agricultural productivity Thus, promoting the healthy functioning
of ecosystems ensures the sustainability of agriculture as it
intensifies to meet the gr
LOSS OF CROPLAND AREA
There has been a growing trend all over the world in
converting cropland to other uses due to increasing urbanization,
industrialization, energy demand and population growth China, for
example, lost more than 14 5 million ha of arable land between 1979
and 1995 (ICIMOD, 2008) owing demands for food production
