The degree of variation Essay On Water Biodiversity life is called; biodiversity.
It is a measure of the variety Essay On Water Biodiversity organisms present in different ecosystems on earth. This can refer to genetic variation, species variation, or ecosystem variation, within an area, biome, or planet. Biodiversity tends to be highest around the equator, which is more info resulted the warm climate and high primary productivity. Biodiversity has not been evenly distributed on Earth.
It is the richest in the tropics. Marine biodiversity is getting to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid-latitudinal band in all oceans.
Biodiversity has been increasing through time but will be likely to slow in the future. Extinction is a fact of life. Species have been developing and dying out since the start of life on earth. This is called the evolution.
However, the amount of endangered species is increasing rapidly nowadays. Previous mass extinctions obvious in the geological record are thought to have been caused mainly due to massive climatic or environmental shifts.
Disappearance of species as a result of changes to the earth that are caused by nature or by the actions done by people. Sometimes natural disasters like a volcano eruption or a hurricane, cause that entire Essay On Water Biodiversity are being wiped away. Sometimes, extinctions happen slowly due to global changes that happen in nature. Humans can also cause the extinction of species. The main reason that species are endangered or threatened nowadays is often because men make changes in their homes or habitats.
So, food, sunlight and shelter. Every different species has to have a specific habitat to stay alive. On the other hand, a tropical birds need to have a tropical habitat like a rainforest to stay alive.
Some species do very well in their new area, which sometimes causes that they endanger other species which already live there. These are species are called native species The introduced species are called invasive species. When some fish are introduced into a lake or stream, for example, they may prey upon the native fish, or eat their food. The native species may then have to find a new source of food or a new home, or they face to become endangered or extinct.
Another way in which people harm species is by taking them from the wild. People might, for example catch an insect like a butterfly for their collection. Others might keep a wild animal for a pet, or pick flowers because it is pretty. In addition, people visit web page hunt animals for food supply or for their skin and fur.
In the past, lots of animals like tigers, rhinos, elephants etc. Were hunted for their ivory teeth which were thought to have a healing ability or their fur. Pollution can affect wildlife as well and can even develop into extinction. If pesticides visit web page other chemicals are not used well, they can poison plants and animals.
One of the animals that was harmed by pesticides, is the bald eagle. A pesticide DDT Essay On Water Biodiversity used by many farmers in the past. Precipitation causes that the pesticides are washed into the lakes and streams, where it poisoned fish. The bald eagles would eat the fish and lay eggs with very thin shells.

Although, the horrible combined mortality rates of World War I and II, Hitler, Stalin, major flu pandemics and Aids, there has been no lowering effect on the rising population levels.
Inthe world population was 2. In the UK, the population increases by the amount of people living in a city, each year. This will demand higher living standards for all which causes the problem to grow even more.
There have been estimates that if everyone in the world lived at the standard of people living in the UK, we would need another three worlds to supply the resources needed or we would need to reduce the world population to 2 billion.
Studies of human diversity have shown that most genetic diversity was found between individuals rather than between populations or continents rather than between populations or continents and that the variation in human diversity can best be described by geographical gradients, or clines. A wide-ranged study, which was published infound that These results show, when Essay On Water Biodiversity around the globe are sampled, the pattern visible is not because of separate clusters but gradients in genetic click to see more that spread over the entire world.
That is why there is no reason to assume major genetic fractures exist between peoples on different continents. The best ways to do this is by reducing their excessive use, people need to start using renewable sources of energy and sustainable use of the minerals for getting maximal result without harming the environment.
Protected areas are an essential part of conservation programs, particularly for sensitive habitats. For instance, tradable development rights, are marketable rights which are awarded to landowners in areas that are reserved for conservation. Essay On Water Biodiversity rights to own and manage ecosystem services to private individuals gives them an interest in the conservation of those services.
A second option could be, direct payments to local landowners to maintain forests on their land. This can contribute to biodiversity conservation, even if this instrument needs continuous financial commitments and sometimes even leads to conflicts.
Water and Biodiversity
Also, you can remove or redirect subsidies that cause more harm than good to help mitigate biodiversity loss. For instance, agricultural subsidies in industrial countries reduce world prices for many commodities, encouraging developing countries to adopt unsustainable agricultural practices. In cities there occur a lot of insects, birds and other Essay On Water Biodiversity. Every plant attracts animals and every plant attracts different species. One plant is more attractive to butterflies when the other is a better place to hide and build nests for birds.
To maintain all these different species, variations is essential, so everyone gets what it needs.
