In life, people have choices, to do right or wrong.
Unfortunately, most of humanity tends to choose disaster.
Planet earth is in turmoil due to the effects of climate change caused by irresponsible human activities over many centuries.
The media has a crucial role to educate the nation on the use of alternative sources of fuel and to encourage people to plant more trees to help reduce the impending climatic disaster.
While in the past the climate has always varied naturally, scientists now believe industrial and agricultural emissions of carbon dioxide and other gases may cause a permanent change in weather patterns.
University of Zimbabwe (UZ) Geography Lecturer, Dr Amon Murwira said the media should continually educate the nation on the use of renewable energy and the importance of replacing every tree cut by planting another one.
“The country can improve its energy efficiency by increasing use of sustainable renewable energy solutions such as solar and gas.
“We should also reinforce tree replacements,” he said.
National Coordinator of Climate Change Office in Zimbabwe, Washington Zhakata says greenhouse gases in the atmosphere act like a mirror and reflect back to Earth a part of heat radiation, which would otherwise be lost to space, hence temperature increases.
Temperature increases not only affect human beings but also other living organisms and the impact can be felt world-wide.
Sweden’s University of Gothenburg’s research revealed that as sea temperatures rise, stocks of some fish species decline while others grow.
The university’s researcher, Albin Gräns, says the gastrointestinal system in fish is much more sensitive to temperature changes than previously believed.
The policy formulation process began in Harare under the leadership of UZ Institute of Environmental Studies to ensure that the country has a well-coordinated and integrated approach to climate change.
The strategy is expected to help government in its planning of climate change adaptation and mitigation programmes.
Involvement of everyone, especially the media is also essential.
In developing countries like Zimbabwe, cities, towns, and provinces can reduce emissions from waste dumps and cement-making, while farmers can adopt new techniques for limiting emissions from fertilisers, livestock, and rice farming.
