In our world today, survival is a must. As Earth becomes older, population of different species increases and decreases. For humans, in order to survive, they must be able to have primary needs such as clothes, shelter and especially the food. For the animals, they need habitat and prey for them to live and for the plants they need water, sunlight and carbon dioxide to grow.
All of us belong in a certain among dependent ecosystem where we used to find our sources. We call ourselves species, from the smallest living organism to the largest. Each of the species have their own role like humans, animals, plants, land, water and atmosphere. They need each one and they are all connected like a chain or cycle. They bind themselves in order to live,

This not only include species but every single living thing in the planet. Biodiversity is important because species, as a part of it, plays an important role to maintain a healthy ecosystem. For further knowledge, Biodiversity is everywhere, it can be on land or water. It starts from microscopic bacteria to the most complex plants and animals. Biodiversity supports the way ecosystem function and provides services such as water and nutrient cycling, regulation of climate and pollination.
Now, why is biodiversity important to us? It satisfy our basic needs like food, shelter and one of the most needed in our generation is the medicine. In the existence of different species of animals and plants in the ecosystem, we are capable now on searching new discoveries that will be essential for human

Second is the habitat loss, forest is the primary habitat of many species in the world which is being deforested all over the world in tropical and non-tropical countries like Philippines. Deforestation is now widely spread for the use of agriculture and shelter of human beings, though we need this in exchange ecosystem in forest are more vulnerable for huge damage and loss. Next is the invasion of non-native species, often over looked cause of extinctions. Non-native species are those exotic and not familiar kind of animal or plant but because if the extinction of native species, those exotic begin to hunt and simply eaten by
The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.
Through millions of years of evolution, well-balanced habitats have co-evolved to provide for the wide variety of species and their needs. Trees have adapted to weeds, weeds have adapted to the predation from herbivores, and so on up the food chain. Similar scenarios are seen throughout the world. Through the process of natural selection, specific species or broad species families will go extinct. However, these occurrences have largely been due to the natural flow and evolution of time. It wasn’t until recently that dominant species, such as humans, have taken the course of nature into their own hands.
“The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests
As you can see biodiversity loss is a very pressing issue and should be prioritized by the prime minister. If we continue to exploit the land and make the species lose their homes, biodiversity will decrease significantly. A vast country like Canada needs its biodiversity because it can add to the richness of the country and can help Canadian citizens. We tend to neglect it but it is very important not only to us but to future generations.
Over the past two centuries, the human population has become increasingly prosperous; nourishment has improved, the economy has developed and longevity has increased. From this, it is possible to conclude that man’s battle with nature is proving beneficial. However, the wellbeing and success of mankind greatly relies on ‘ecosystem services’, which comprise any benefits provided by ecosystems that contribute towards human life. These developments in wellbeing have partly been achievable because of the increased exploitation of these ecosystem services.
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
The United Nations designated 2011-2020 as the United Nations Decade on Biodiversity. In biodiversity, each species, no matter how big or small has an important role to play in ecosystem. Various plant and animal species depend on each other what each offers and these diverse species ensures natural sustainability for all life forms. A healthy and solid biodiversity can recover itself from variety of disasters. It is estimated that the current species extinction rate is between 1,000 and 10,000
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”). 2. And acid rain, which is created when water in the atmosphere mixes with chemicals, ravage through rain forests and can even kill fish. 3.
== = = Human beings are dependent on the Earth's diversity of species for our survival. Wild species play a vital role in the maintenance of the planets ecological functions, yet everyday on the planet 40-100 species become extinct.
The most interesting thing that I have learned about Biological Geography this semester is biodiversity hotspots. Before taking this class I had no clue what biodiversity hotspots where and how big of a role they play on humans. Biodiversity hotspot is biogeographic region with a significant reservoir of biodiversity that it is under threat from humans. The idea of biodiversity first was introduced by Norman Myers and many scientist have contributed on this idea.
Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain.
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
Some main causes of Endangerment are habitat loss, pollution, hunting, competition from non-native plants and animals, plant collecting, logging, clearing forests, and trading animal parts. The growing population also causes some effect because man cause most problems. Diseases or viruses are al...
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
