A report on the Garbage dump in Karachi and the effect global warming may be having on the climate in Pakistan as a result of pollution and waste disposal. Karachi, Pakistan. 15/12/2009.
The agricultural ecosystem can collapse due to global warming and associated risks as it is feared that rising temperature can lead to catastrophes like droughts, water shortages, productivity and biodiversity loss across the world,
70 percent of the total land of Pakistan was located in arid and semi-arid regions, while droughts and loss of biological productivity were common phenomena in the country.
Pakistan was confronted with environmental deterioration in agro-ecosystem and it may cause change in land use due to contamination of farmlands by chemical pollutants from industries.
The two-week UN Climate Change Conference 2009 began in Copenhagen. Delegates from 192 countries are attending. Danish Prime Minister Rasmussen told the delegates that there was an urgent need for a “strong and ambitious climate change agreement”. He also described the climate summit as an “opportunity the world cannot afford to miss”.
Mr Rasmussen’s words are hauntingly true. Global warming is overtaking the planet at a far greater speed than was estimated in the past. According to many scientific reports, rapid changes in climate are already affecting biological patterns in every continent. According to the latest Intergovernmental Panel on Climate Change (IPCC) report, it is more than 90 percent probable that mankind is largely responsible for modern-day climate change. The principal cause is burning fossil fuels coal, oil and gas. The common editorial on climate change published in Daily Times on the eve of the summit warned that there is very little time left to limit the damage of global warming.
Pakistan is hardly at the forefront of the climate change campaign, but like all other countries of the world, it too is bearing the brunt of global warming. We come in the category of rain-deficient countries, which is why the news that the Himalayan glaciers are meting at an alarming rate is quite worrisome for not only Pakistan but all of Asia. This would eventually lead to drought all over the continent as these glaciers serve as storage tanks of our river and irrigation system. Though the prospects of a treaty being signed at the Copenhagen summit are not bright, yet we would advise the developed and developing countries of the world to set aside their differences and take remedial steps.
Historically, the main polluters have been the rich countries the US and China together produce 40 percent of the world’s greenhouse gas emissions but since action to cut down on carbon emissions is being demanded globally, the poor countries are also being asked to make sacrifices. The world must take a just approach in this matter. The new treaty on climate change should ascribe responsibility so that the burdens are shared equitably. In other words, developed countries should support developing countries in tackling climate change and share the costs. On their own, the developing countries would not be able to afford all the changes needed to reduce fossil fuel emissions, which is why the developed nations must loosen their purse strings and help make it a truly global project. This year’s climate summit began with a filmed plea from children. The message at the end of the film was, “We have the power to save the world. Now.” The world must pay heed to this message immediately or else the consequences would be catastrophic.
