Global warming: causes, impacts and solutions.

Thesis statement

        Global warming is caused due to excessive use of fossil fuels, role of agriculturesector,deforestation,and other anthropogenic activities posing threat of climate change, health hazard, and imbalance in ecology, however, these hazards can be mitigated by supplanting the fossil fuels with alternate energy source, technological interventions massive forestation and inculcating awareness to public.

Outline

        I.            Introduction

      II.            Causes of global warming

      a.Excessive use of fossil fuels –Greenhouse Gases effect

1.       use of fossil fuels in industry particularly energy sector and brick kilns

2.       use of fossil fuels in vehicles and transport

3.       Domestic use of fossil fuels for cooking and heating

4.       Household equipment –chlorofluorocarbons effect

b.Contribution of agriculture sector in global warming

1.       Use of agriculture using fossil fuels

2.       Burning of crop residue by farmers

3.       Use of fertiliers,pesticides-a source of CFCs

4.       Role of crops in global warming

5.       Contribution of live stocks in global warming

    C.Deforestation leads to imbalance in oxygen cycle.

1.       Deforestation to obtain wood for industrial, commercial and domestic use

2.       It leads to increase in carbon dioxide

3.       It has negative impact on ecology.

D. other anthropogenic activities leading to global warming.

1.       burning of solid waste particularly plastic substance and rubber

2.       burning of Tyres during protests

3.       urban fire due to human negligence

III.Impacts of global warming

 a.Global warming has adverse effect on climate change.

1.       melting glaciers melting ice cause floods

2.       super cell storms, increasing tornados,hurricanes,typhoons,and flooding becomes more common

3.       Rising sea levels pose threat to coastal areas

4.       Worsening droughts pose threat to human and animal life.

 

B.Global warming poses threat to human health.

  

1.       Scorching heat waves pose threat to human life

2.       Smog and soot cause respiratory diseases

3.       Vector and virus attack like corona

   

c.Impacts on agriculture crops and ecosystem

 

1.       Challenges to food security

2.       Low agriculture production to weather variation

3.       Pests and disease attack on crops

4.       Shift in forest types

5.       Extinction of many species of plants,fish,animals,birds

 

IV. Solutions to address the situation.

 

 

1.       Switching over to renewable anergy source

2.       Ensuring massive forestation to maintain oxygen cycle

3.       Introducing technological interventions to reduce greenhouse gas effect

4.       Inculcating awareness among farmers for scientific disposal of crop residue and use of organic manure

 

 

V.Conclusion
