Frogs and koalas are both endangered animals. They are both having some complications with their habitats. But they have dissimilar things as well. Such as, living, food, and their safety. One of the reasons that koalas are endangered is because people are trying to harm them by cutting down the trees they live and feed off.
Plutella xylostella (L.), the diamondback moth (DBM), is a serious pest of crucifers and has been reported from all US states. The most affected vegetable crops in the United States are cabbage, broccoli, cauliflower, collard, mustard, radish, and turnip and major damage to the crops is caused by larval feeding. DBM has been known to travel long distances (Chapman et al., 2002). The annual total estimated cost for DBM management is 4 to 5 billion dollars globally and 150 to 200 million dollars in the United States (Zalucki et al., 2012). Despite many advances, DBM has retained its status as the most destructive member of the different insect pest complexes that attack crucifer crops in various parts of the world and has shown the substantial
This article included many information such as,“Clapper rail survival patterns were consistent with hybrid Spartina providing increased refuge cover from predators during tidal extremes which flood native vegetation, particularly during the winter when the vegetation senescence” (Invasive Species…). We know that the most important factor that affects the clapper rail’s population is their surrounding, in order to help them we must start by removing invasive plants and replace it with plants that is helpful. The increase in invasive plants decrease the amount of spaces in which the clapper rail can build their nest, it causes many birds to die because of the lack of habitats. The invasive plants can also kill the harmless plants by taking away their nutrient, and it might take away all the possible space for nests. We can change this by replacing the invasive plants with harmless plants and even build nests for clapper
More often found on the wildlife and vegetation, especially in the tissues of fish in the rivers, thus causing serious health issues to humans eating high amounts of fish. Overall, the California Gold Rush based on history did not have many contributions and positives to the environment. The race for economic prosperity, and striking gold came at a cost with the destruction of the environment. The difficulty of extracting gold took a toll on the farmlands, hillsides, and mountains of the Sierra Nevada
The illegal hunting and trade of primate meat is a large contributing factor to the decline of primate species in the tropics. This, in addition to habitat loss and fragmentation, disease, and the pet trade, is putting many primate species at high risk of extinction. Poverty, population growth, construction of roads, emergence of regional and international markets, and new hunting technology are triggering the increased hunting pressure on forest mammals. Primate species are especially vulnerable to increased hunting pressure because of their slower reproductive cycles. The decline of primate species must be stopped to avoid their extinction and the potential consequences that this could have for tropical forests.
Some issues are also industrialization, which is killing our natural habitats. Disease and parasites are another problem that is affecting our bees health and making their job hard for them. Also another concern that people think could be a main reason for the decreasing population is the increased used of pesticides on farms, using pesticides on farms makes it difficult for the bees to survive because of the toxins. If our environment continues to have harsh living conditions, or we continue to use chemicals that can affect our bees then it could possibly lead us to their
The python and another snake known as the Tree snake have caused the extinction of 10 native species, including the Songbird, some lizard species, and bats (Florida 's Python Problem: Snakes Reshape the Everglades). Florida is doing its best to maintain the species, but its getting to a point where its starting to become to late to stop them. It seems that the species has already taken a firm root upon the Florida Everglades. The fear too is that the snake will continue moving more north and spreading itself out into other regions of the US. This is why it is crucial to stop them because different regions contain different species, and most likely, the snakes will be on the higher end because of their size, their sneakiness, and their strength.
In a website Causes and effects of environmental pollution- conserves energy future.(2009). There is an article the writer says that ''acid rains can change the composition of the rivers and the sea, making them toxic for fishes, because the quality of ozone in the thower plants of the atmosphere can causes lung to all animals". that’s shows that what people do it comes back to them in bad effects that they may kill all the animals that they need them for therapy and they may cause a diseases that ends human life . Also as we know that also the plants damaged from the pollution that they may be extinct and people cannot have a good healthy and fresh air that they maybe be sick from it and also the soil will be not good to plant in it and
Reasons for this bird to be put on the endangered list is because of the accumulation of organochlorine pesticides in fish, which bald eagles were feeding off of. Those pesticides interfered with the ability of the birds to produce viable eggs. Another reason is loss of nesting and wintering areas due to development along rivers. Indiscriminate shooting was responsible also for keeping the population down until the passage of the Bald Eagle Act of 1940. With that bald eagles have made a strong
Endangered specie populations in Mexico Introduction: Humans have drastically modified wildlife by polluting the earth we live in. Pollution is one of the major insidious threats to the environment, it ranges from obvious action, such as dumping in rivers and lakes to sprayed undetected chemicals. However, if the effect is permanent or short term the outcome does not change. Pollution changes the balance of ecosystems which causes numerous animals to become extinct. For example, the Bald eagle, peregrine falcon, and brown pelican all became endangered or extinct prior to scientists finding out that the chemical DDT, a chemical used largely in the United States as a pesticide.
