The authorities must give adequate attention to preserving the environment
Of all the five most critical factors that affect the global environment, namely, air pollution, overpopulation, deforestation, climate change and global warming, the biggest threat to Nigeria’s environment remains deforestation. This is without losing sight of the waste management challenges, flooding, desertification, gully soil and coastal erosion that bedevil various parts of the country. There is therefore an urgent need for environmentally and socially equitable approaches to forest management, especially at a time the nation’s forests are being taken over by bandits and sundry other criminals.       
Even before the issue of criminal encroachment, many of our forests had been threatened by bush burning and illegal logging, a situation worsened by the absence of measures aimed at their regeneration. That the authorities have not responded to the problem is what is particularly troubling. Ordinarily, forests are home to wildlife which perform a broad range of critical environmental and climatic functions including the maintenance of constant supply of water and ensuring clean air and prevention of desertification, soil, and gully erosion. Forests harbour species and at the same time have very deep economic, aesthetic, industrial and religious significance for humans.  
 As things stand today, less than 4% of the country’s untouched forest cover is left. More frightening is the fact that the loss has continued unabated at the rate of 3.5% annually. Some 1.5 million trees are felled every day owing to illegal logging. About 484 plant species are also threatened with extinction in Nigeria.  
Nevertheless, Nigeria’s remaining forests harbour about 4000 different species of plants including those that have been found to be effective in the development of alternative medicine. There are also animals, including birds that can only be found in Nigeria and nowhere else. These include the Ibadan Malimbe, the Anambra Waxbill, the Jos Indigo Bird, and the white throated Monkey (Cercopithecus erythrogaster pococki), the Niger Delta Pigmy Hippo and the Red Colobus Monkey. All these important species are threatened by habitat loss apart from other anthropogenic or human factors.      
 The desert is still encroaching at the speed of more than 1.6 kilometres annually. There are almost 3,000 erosion sites in the Southeast. Flooding in Lagos is anything but ordinary. Rising temperature is increasingly becoming unbearable while agriculturists are struggling to adapt to the attendant climate variability with serious socio-economic implications. The National Park Service that is charged with the responsibility of protecting swathes of forests and their biodiversity is lacking in capacity apart from being inadequately funded and supported.       
Against this backdrop, therefore, we must completely reset the country’s environmental agenda. The fight against insurgency and banditry should be ramped up to rein in the devastation and degradation of the natural environment across the country. Environmental remediation measures such as the Great Green Wall Project should be taken more seriously and adequately funded. The federal government must order a thorough review of the Environmental Impact Assessment (EIA) report of some huge projects of serious environment impact such as the Eko Atlantic City.       
Stringent statutory provisions should be put in place to protect the various ecosystems and their biodiversity. There should be more transparency and accountability in the application of Ecological Funds – the funds must be made to serve its purpose fully and directly. Tougher measures should be put in place to checkmate wanton emission of noxious and deleterious gases through gas flaring and use of outdated machines. Electricity challenges in the country should be addressed to minimise the use of power generating sets. The Green Recovery Project of the Nigerian Conservation Foundation (NCF) must attract deserved encouragement and partnership.
