The environmental impact of agriculture involves a variety of factors from the soil, to water, the air, animal and soil diversity, plants, and the food itself. Some of the environmental issues that are related to agriculture are climate change, deforestation, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Of climate change mitigation consumption options investigated by a review, the consumption options with "the highest mitigation potential advocate reduction in car and air travel". [106] A study projected a potential reduction of "transport direct CO 2 emissions by around 50% in the end of the century compared to the baseline" via combined ...
Climate scientist Kevin Anderson raised concern about the growing effect of air transport on the climate in a paper[13] and a presentation[14] in 2008. He has pointed out that even at a reduced annual rate of increase in UK passenger air travel and with the government's targeted emissions reductions in other energy use sectors, by 2030 aviation ...
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus , where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times."
Reducing air travel may have a positive effect on climate change but it will inevitably damage developing countries that rely on tourism for their chances of prosperity.
The Intergovernmental Panel on Climate Change (IPCC) estimates a commercial jet's flight to have some 2-4 times the effect on the climate than if the same CO 2 emissions were made at ground level, because of different atmospheric chemistry and radiative forcing effects at the higher altitude. [5]
The solution for reducing port-related pollution is multi-fold, encompassing attainable alternatives and long-term reduction goals. Examples of simple steps include a restriction on engine idling for ships in the port and the use of cleaner grade diesel fuels. Some more expensive measures can be taken to mitigate the pollution of ships.
Human uses of marine ecosystems and pollution in marine ecosystems are significantly threats to the stability of these ecosystems. Environmental problems concerning marine ecosystems include unsustainable exploitation of marine resources (for example overfishing of certain species), marine pollution, climate change, and
