Climate changes associated with rising green house gases are increasing frequency and intensity of heat waves, severe storms, and floods, as well as elevated sea levels. The temperature is fluctuating rapidly. The summers are getting hotter and the winters are getting colder. Approximately, 30% of the agricultural lands worldwide could be affected by these changes so global warming is projected to have considerable effects on agriculture.
- A warming of 2° Celsius or more could reduce the production of global food supplies and aggravate world hunger.
- The impact on crop yields will vary considerably across different agricultural regions.
- Warm regions, such as tropics and subtropics, will be threatened by climate change, while cooler regions, mainly in temperate or higher latitudes, may benefit from warming.
Global climate change may have significant effects upon livestock systems as well.
- First, the productivity and quality of rangelands may be adversely affected. This in turn will affect the quality and productivity of livestock.
- Second, higher grain prices resulting from the disruption of crop production will lead to higher costs for livestock products.
- Third, increased severity and frequency of storms may intensify soil erosion and decrease the productivity of rangelands.
- Fourth, global warming could result in changes in the distribution and severity of livestock diseases and parasites, which may threaten the health of animals, especially those in intensively managed livestock systems.
If the Greenhouse Gases continues to increase our home planet Earth would become inhabitable soon. We hope that we will be able to check Greenhouse Effect to ensure human survival.
