Human Activities and Loss of Habitat, 2. Deforestation, 3. Desertification, 4. Marine Environment, 5.
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.
Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources.Promote soils formation and protection. Provide for nutrient storage and recycling.
While protecting the rainforests sounds like a daunting task, there is a lot you can do to promote and preserve local biodiversity at home.
- Support local farms.
- Save the bees!
- Plant local flowers, fruits and vegetables.
- Take shorter showers!
- Respect local habitats.
- Know the source!
The loss of biodiversity has two significant impacts on human health and the spread of disease. First, it increases the number of disease-carrying animals in local populations. At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease-carrying species.
8 Major Causes of Biodiversity – Explained!
- Habitat Loss and Fragmentation: A habitat is the place where a plant or animal naturally lives.
- Over-exploitation for Commercialization:
- Invasive Species:
- Pollution:
- Global Climate Change:
- Population Growth and Over-consumption:
- Illegal Wildlife Trade:
- Species extinction:
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species. Through proper education, and by demanding that governments make decisions to preserve biodiversity, the human population will be able to sustain life on earth longer.
Ecosystems underpin all human life and activities. The goods and services they provide are vital to sustaining well-being, and to future economic and social development. The benefits ecosystems provide include food, water, timber, air purification, soil formation and pollination.
The main human activity that affect biodiversity are habitat destruction, foreigner species importation and hunting.
Much of the Earth's biodiversity, however, is in jeopardy due to human consumption and other activities that disturb and even destroy ecosystems. Pollution, climate change, and population growth are all threats to biodiversity. These threats have caused an unprecedented rise in the rate of species extinction.
These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Human interaction within ecosystems can have both positive and negative impacts on the levels of biodiversity. replanting hedgerows because there is higher biodiversity in them than the fields they surround. reducing deforestation and the release of greenhouse gases. recycling rather than dumping waste in landfill
This means that human beings needs biodiversity the same as biodiversity needs human beings. Therefore, the Earth cannot exist without human beings for they both need each other. That being said, biodiversity greatly needs human beings too to take care of them to continue growing or existing.
Human activity is by far the biggest cause of habitat loss. The loss of wetlands, plains, lakes, and other natural environments all destroy or degrade habitat, as do other human activities such as introducing invasive species, polluting, trading in wildlife, and engaging in wars.
How to maintain a balanced ecosystem
- Manage Natural Resources Carefully. A concerted effort to use natural resources in a sustainable manner will help to protect and maintain ecological balance.
- PROTECT THE WATER.
- reduce logging.
- reduce chlorofluorocarbon.
- Stop open burning.
How to Combat Habitat Loss. Combat habitat loss in your community by creating a Certified Wildlife Habitat® near your home, school, or business. Plant native plants and put out a water source so that you can provide the food, water, cover, and places to raise young that wildlife need to survive.
Local governments can adopt critical area overlays, wetland and floodplain ordinances, agricultural protection zoning, and urban growth boundaries that protect critical habitat and resources and direct growth away from them.
31+ Stunning Ways to Save the Environment from Destruction
- Change the way you get around.
- Be mindful of eating habits.
- Grow your own food or buy it locally.
- Embrace secondhand shopping.
- Replace standard products with energy efficient versions.
- Buy recycled products.
- Spread the word.
- Stop using plastic water bottles.
The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world's ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and
The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.
