The development of the stadiums, parks, houses, warehouses have taken up the area of the wetland, reducing its size. These developments were created to keep up with the large urbanisation rate the area was receiving. Most of the creeks and waterways were built over for development reasons. There was a destruction of the mangroves, saltmarsh and
Increase in sea-level will result in the loss of intertidal habitants if floods defenses are maintenance (Crooks, 2004). Habitants loss in intertidal areas is likely to exert impact on shellfish cultivations, while finfish aquaculture may be less affected (Callaway et al, 2012). The rise of sea-level is expected to destroy areas where sand belts are important to protect the lagoons
Overfishing depletes our surrounding waters of the sea creatures that bring in millions of tourists to the Bahamas, keep the underwater ecosystems alive and well, employ hundreds of Bahamians and feed many more. These are all obstacles that we must overcome in order to utilize our marine industry to its
The sheer range of numbers alone suggests the limited extent of our knowledge of these forests. For example, whereas temperate forests are often conquered by a half dozen tree species or fewer that make up 90 percent of the trees in the forest, a tropical rainforest may have more than 480 tree species in a single hectare (2.5 acres). A single bush in the Amazon may have more species of ants than the entire British Isles. This diversity of rainforests is not a chaotic event, but is the result of a series of unique circumstances.A tropical rainforest is typically divided into four main layers, each with different plants and animals modified for life in that particular area: the emergent, canopy, understory, and forest floor layers. Emergent layer The emergent layer contains a small number of very large trees called emergents, which grow above the general canopy, reaching heights of 4555 m, although on occasion a few species will grow to 7080 m tall.
It could also be fresh, brackish or saline. Wetland management: Wetland management normally include those activities that can be accompanied within or around wetlands. These activities could be both natural and man-made which are conducted to protect, restore, or provide for their functions and values. Wetlands are present from the tundra to the tropics and on every continent except Antarctica. Pakistan is blessed with about 225 important man-made and natural wetlands which are spread over nearly 10% of the country.
Wetlands play major role in the landscape by providing unique habitats for a wide variety of flora and fauna. They support a wide variety of plant, and microbial species where the species come from both terrestrial and deep water aquatic systems to reproduce,find refuge, eat, or be eaten. Morerecently, wetlands are being described as important water quality enhancement ecosystems and flood mitigation systems and carbon sinks and climate stabilizers on a global scale. These ecosystem services of wetlands are now recognized worldwide and have led to wetland conservation, protection laws, regulations, and management plans. Wetlands have become the cause for conservation minded people and organizations throughout the world, in part, because they
If we do not get the oxygen we need we will not be able to breath the people will get sick and die. Then when people start to die the population will start to decrease in the rainforest . The animals are in the rainforest are in danger by other animals that they see them as a threat and try to attack to keep themselves alive. There are major threats to the rainforest such as mining, agriculture, hunting, fishing, ranching, and smuggling. Some animals keep themselves safe by camouflaging there surroundings.
Thus, when forests are removed, it is less likely to rain. There will also be lesser trees to facilitate more water to infiltrate the ground and funnel water into underground aquifers where it is stored to supply during droughts. Hence, deforestation has resulted in flash flood during heavy rainfall, and without the roots holding the soil, it will eventually lead to soil erosion. Furthermore, the soil will be washed away into rivers when there is heavy rainfall, causing river carrying capacity to be reduced and thus, increasing the risk of floods. Both droughts and floods carry severe consequences as eroding topsoil, flooding rice fields and filling in irrigation canals will constrain food production.
It locally known as udang galah is distributing from north-west India to Asia (Banu & Christianus, 2016). In Malaysia, the freshwater shrimp can be found in most inland freshwater areas including ponds, rivers and lakes. The adult freshwater shrimp requires a brackish environment in freshwater function for the larvae development (Mohd Shamsudin et al. 2013). Nowadays, consumers prefer seafood crustacean especially freshwater shrimp Macrobrachium rosenbergii
In such cases, it is as often as possible termed as gardening dry season. Human Causes Human activities affect a generally big and critical part in the administration of the water cycle. Human acts, for example, deforestation, development, and farming contrarily affect the water cycle. Trees and vegetation spread are fundamental for the water cycle as it cutoff points vanishing, stores water, and pulls in precipitation. In this sense, deforestation – clearing vegetation cover and chopping down trees causes the water to just sit there and not be absorbed by any plants or trees which result in it being evaporated directly.
