The use of fertilizer would result in more nitrogen in the groundwater. The use of fertilizer would result in less nitrogen in the soil. The use of fertilizer would result in more phosphorus in the soil. The use of fertilizer would result in more nitrogen being added to the carbon cycle.Which one of the following measures CANNOT mitigate emissions of greenhouse gases in aquaculture?

- the following are key features in biomimicry: i.population control ii.cooperation iii.food production Give examples in ecosystems and where such practice has been usedWhich one of the following sentences is NOT true? Select one: Compared with other land-based food production systems, fisheries and aquaculture have a relatively small overall carbon footprint. Global fish production from capture and culture operations contributed up to 1.5% to the world’s CO2 emissions. CO2 emissions by marine and inland fishing vessels were about 0.5% of the total global emissions. Being a minor contributor in global terms, fisheries and aquaculture have no opportunities to mitigate emissions of greenhouse gases.Essay on Environmental Sustainable Development with examples
