Aquaculture allows for fish to be farmed for production and provide more jobs for the local people of Nigeria. Overfishing is not the only impact on marine communities. Climate change, habitat loss, and pollution are all added pressures to these important ecosystems. The banks of the Niger River are desirable and ideal locations for people to ...
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
The increase in population also has led people to rely on cropping as a source of income, but many do not take measures to protect the soil, [11] due to low income. [12] The current methods create too much pressure on other environmental aspects, such as forests, and are not sustainable. [13] There are also ecological causes of the poor soil ...

The human visual system is generally believed to be sensitive to visible light in the range of wavelengths between 370 and 730 nanometers of the electromagnetic spectrum. [3] However, some research suggests that humans can perceive light in wavelengths down to 340 nanometers (UV-A), especially the young. [ 4 ]
The eye facets of Platycnemis pennipes collect light directly or incidentally. That gives environmental information to the insect. Polarization is a property of light waves that describes the orientation of their oscillations. Polarized light pollution [1] is a subset of the various forms of light pollution referring specifically to polarized ...
It was one of the worst droughts in Africa’s history, affecting about 100 million people and killing about 250,000 people. [29] The drought of 1972 and 1973 was attributed to the death of 13% of animals in the north-eastern Nigeria and an annual agricultural yield loss of more than 50%.
The Olusosun nigerian dumpsite is a 100-acre [1] dump in Lagos, Lagos State, Nigeria. [2] It is the largest in Africa, and one of the largest in the world. The site receives up to 10,000 tons of rubbish each day. Waste from around 500 container ships is also delivered to the site, adding a substantial portion of electronic waste. Some of this ...
