FARM FISHING: THE SOLUTION TO OVERFISHING?
03/02/2017 MARC ARENAS CAMPS 9 COMENTARIS
We have heard many times that fishing grounds are being depleted due to the overexploitation of species. It is also widely said that farm fishing could solve this problem. But, are farms the solution to overfishing?
FARM FISHING: THE SOLUTION TO OVERFISHING?
In general terms, the status of wild fish stocks has not improved. By 2013, 58.1% of fish stocks were fully exploited, 10.5% were under-exploited and 31.4% were overexploited (FAO, 2016). Thus, 30% of the populations suffered from overfishing.
This is due to the increasing consumption of fish. According to a report published by FAO, in 2014 each person ate on average about 20 kg of fish, twice as much as in 1960.
On the other hand, since the 1980s, wild catches have remained stable. However, the supply of fish for human consumption has increased considerably. So, if consumption has increased and fishing has remained stable, where does the rest of the fish come from?
The explanation for this fact is in aquaculture: in 2014, catch production was 93.4 million tonnes, while aquaculture production amounted to 73.8 million tonnes. In other words, 44% of the fish came from aquaculture.

What happens during coal formation after plants die and fall to the bottom of a swamp.
Answer:
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Explanation:
When plants die, they are no longer in contact with the air. The pressure of rocks and the earth makes the plant matter undergo a chemical change witch transforms the plant matter into coal. The process takes millions of years. This is one of the reason why coal is a non-renewable natural resource.

A comprehensive map of a piece of land's topography shows its surface features. It encompasses the hills, mountains, creeks, and other lumps and bumps on a certain piece of ground.
The shape and relief of the land are described by the slope and topography. Slope is the percentage change in elevation over a given distance and topography is a measurement of elevation. Lines connecting places with the same height can be used to measure topography; these are known as topographic contours.
Thus, climate, Topography, Water Resources and Natural Habitats.
