Over the years, the decline of family farms and increase of factory farming has caused harmful effects on human life. Some health problems that effect consumers are respiratory infections, food poisonings, obesity, E. coli, Staphylococcus aureus (MRSA), and obesity. A lot of individuals are becoming increasingly aware of the health effects of factory farming. Two solutions that would help decrease the harmful effects of factory farming are making the living and manufacturing conditions of the livestock more humane. Another solution to help decrease the harmful effects of factory farming are feeding the livestock a natural diet with limited use of antibiotics and pesticides.
Irrigated Soil Irrigating water over and over again, until it is overused. This means the natural cycle of water no longer happens. Ocean Water Resource Challenge Description Over Fishing Fishing to the intent that we take out more fish that can be put back. Sewage This happens when people either dump their garbage in the water source, or do not dump at all. Both cause population within the water system.
The chlorides are absorbed by the roots instead, growing to toxic levels. When the grass contains too much chloride, it can't produce chlorophyll effectively and it will starve the roots so when it can't turn the sun's light into energy. If you use either rock salt and or table salt these two will melt ice. It will then begin to create a combination of water and salt or “saltwater”. When growing grass, flowers, and plants we use water.
An example of aquaponics, which is a combination of hydrophonics and aerophonics, in the UK is in Wakefield, West Yorkshire. The waste from the fish which are reared there is used as nutrients for the plants, and the plants filter water for the fish. So this technique is sustainable, but arguably can only be small scale and currently is not a realistic food source for large populations. Another strategy is a push in sustainable agriculture, which is the production of food indefinitely without damage to the environment, but causes of unsustainable agriculture such as resource imbalance, policy failure and unsuitable technologies have been identified by the FAO. Sustainable ways of farming is extensive systems in low population
Furthermore, the reservoir also covered many unexcavated archaeological sites, destroying irreplaceable ancient heritage. 2. How does the Three Gorges Dam relate to the issues of global warming, biodiversity, and water pollution discussed in this chapter? The Three Gorges Dam reduced the emission of C)2 by thermoelectricity factory; it has also prevented the pollution that was entering into the river. The main cause of reducing biodiversity was preventing the stream and also prevented the movement of the migration of fish was blocked, and plants and animals adapted to the river habitat would die out.
The roots became waterlogged; an unsuitable condition for the trees and death resulted. This created conditions favorable for the sedge grass which however, altered the ecosystem to be less favorable for them and they are succeeded by the sphagnum and moss. The sedge grasses formed the peat due to decomposition. The peat accumulated and gradually reduced the pond size and depth until the pond disappeared, resulting into a small stream. The peat provided the substrate for the growth of trees over time; a bog forest was the final succession.
GLOBLE PHOSPHORUS CYCLE: That benign-looking pond scum signifies a far-reaching shift in the global phosphorus cycle. Think of global environmental change, and you'll probably think most immediately of such sweeping atmospheric phenomena as global warming or ozone depletion. Many of the other environmental disruptions we're familiar with-toxic dumps, decimated forests, eroded fields-seem largely confined to particular localities. Yet there are some environmental changes that, while appearing to be locally confined, are in fact manifestations of worrisome global patterns. Look at the algae forming on a local farm pond, for example, and you're seeing the result of a process-the phosphorus cycle-that extends far beyond that farm.
Eutrophication can cause the overgrowth of algae, too many bacteria, and the death of fish. Other human sources of phosphate are in the out flows from municipal sewage treatment plants. Without an expensive tertiary treatment, the phosphate in sewage is not removed during various treatment operations. Again an extra amount of phosphate enters the water.
This can lead to an overgrowth of algae, too many bacteria and the death of fish. (Wright & Boorse, 2013) The Nitrogen cycle is the flow of nitrogen gas that mainly occurs through the air. An example of this is when you take your pet out for a walk and they release waste, while the waste is breaking down it is releasing nitrogen gas into the air. Humans effect this cycle the same way as the carbon cycle. When fossil fuels are released into the air at a rapid rate it can cause nitrogen to go from the air to the ground faster.
Others are famous for nature reserves. If any of these are damaged by wiping out an entire species then tourism could significantly decrease to the town/city. Rising temperatures may also have a more permanent effect on food webs world-wide. Organisms, on the whole, are adapted to a specific niche and so therefore unable to adapt to changes in their environments. This means that the organisms that are living in the more extreme
