Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. Deforestation can lead certain tree species to permanently disappear, which affects biodiversity of plant species in an environment.
Why does biodiversity matter to us?
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat.
Why is loss of biodiversity bad?
Loss of biodiversity undermines the ability of ecosystems to function effectively and efficiently and thus undermines nature's ability to support a healthy environment. This is particularly important in a changing climate in which loss of biodiversity reduces nature's resilience to change.
What is biodiversity and why it matters?
What is Biodiversity? The term biodiversity was first coined in 1985, a contraction of “biological diversity.” In broad terms it means all life on Earth from microbes to rainforests, and how that life interacts with each other. Essentially, it is the fabric that holds the planet – and every life on it – together.
What happens if biodiversity is destroyed?
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.
What will happen when biodiversity disappears?
As species disappear, gaps begin to appear in the ecosystems. Small at first but as each species relies upon others, losing one has a knock-on effect, causing others to be adversely affected. As more and more gaps appear, the whole ecosystem will begin to break down and many of the other species will be lost as well.
What are 5 reasons why biodiversity is important?
Why biodiversity is key to our survivalBiodiversity ensures health and food security. Biodiversity underpins global nutrition and food security. ... Biodiversity helps fight disease. ... Biodiversity benefits business. ... Biodiversity provides livelihoods. ... Biodiversity protects us.
How does biodiversity loss affect human health?
Biodiversity loss and ecosystem change can increase the risk of emergence or spread of infectious diseases in animals, plants and humans, including economically important livestock diseases, zoonotic outbreaks and global pandemics.
How important is biodiversity to the human lives?
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.

Why is biodiversity important?
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have healthy ecosystems.
Where is biodiversity loss most pronounced?
Biodiversity loss has been most pronounced on islands and in specific locations around the tropics.
What is biodiversity in biology?
At its simplest, biodiversity describes life on Earth – the different genes, species and ecosystems that comprise the biosphere and the varying habitats, landscapes and regions in which they exist. We've answered some of your most popular questions about biodiversity.
How do trees help the environment?
When they are removed it can increase flooding. Trees and other plants clean the air we breathe and help us tackle the global challenge of climate change by absorbing carbon dioxide. Coral reefs and mangrove forests act as natural defences protecting coastlines from waves and storms.
How long has the loss of habitats been taking place?
Loss of natural habitats has been taking place over thousands of years, but scientists are confident that we have ways to help biodiversity recover.
How many hectares of tropical forest have been lost in the world?
Forests contain some of the richest concentrations of biodiversity on the planet. But between 1990 and 2020, around 420 million hectares of mainly tropical forest has been lost.
How many species of life are there on Earth?
Biodiversity is all the living things on our planet – from the smallest bacteria to the largest plants and animals. So far, we have identified around 1.6 million species but that is probably only a small fraction of the forms of life on Earth.
Why is biodiversity important?

How does biodiversity help our economy?
1. Biodiversity ensures health and food security. Biodiversity underpins global nutrition and food security.
Why do animals live in close quarters with each other?
As a result, animals live in closer quarters with one another and with humans, creating ideal conditions for the spread of zoonotic diseases. Simply put: more species means less disease. Human activity is eroding biodiversity. Image: World Economic Forum Nature Risk Rising.
How much of the world's GDP is dependent on nature?
According to the World Economic Forum's recent Nature Risk Rising Report, more than half of the world’s GDP ($44 trillion) is highly or moderately dependent on nature. Many businesses are, therefore, at risk due to increasing nature loss.
Why is conservation important?
People once understood that the conservation of species was crucial for healthy societies and ecosystems. We must ensure this knowledge remains part of our modern agricultural and food systems to prevent diet-related diseases and reduce the environmental impact of feeding ourselves.
Does biodiversity increase human health?
Higher rates of biodiversity have been linked to an increase in human health.
Is biodiversity loss a threat to humanity?
Biodiversity loss and climate change are occurring at unprecedented rates, threatening humanity’s very survival. Nature is in crisis, but there is hope. Investing in nature can not only increase our resilience to socioeconomic and environmental shocks, but it can help societies thrive.
Why is protecting nature important?
Protecting nature can help keep us safe and healthy — find out how. Nature is not only beautiful, but billions of people rely on it. Wild spaces and their animals are being eradicated at a break-neck speed — country and corporate leaders can help.
Why is it important to protect wild animals?
Protecting and sustainably managing nature can help prevent climate change, a crisis that could imperil our species. Our wild spaces are also home to indigenous communities, many of whom are diligent protectors of their lands and water, and important medications can be linked directly back to nature.

Wild spaces and their animals are being eradicated at a break-neck speed — country and corporate leaders can help.
How does biodiversity loss affect the ecosystem?
Biodiversity loss disrupts the functioning of ecosystems, making them more vulnerable to perturbations and less able to supply humans with needed services. The consequences are often harshest on the rural poor, who depend most immediately upon local ecosystem services for their livelihoods, and biodiversity loss poses a significant barrier to meeting the Millennium Development Goals.
What is biological diversity?
Biological diversity, or biodiversity, is the term given to describe the variety of life on Earth. It reflects the number, variety and variability of living organisms and how these change from one location to another and over time.
How does human impact the environment?
The impact of humans on the natural environment is significant and growing , causing changes in biodiversity that have been more rapid in the past 50 years than at any time before in human history. As demographic pressures and consumption levels increase, biodiversity decreases, and the ability of the natural world to continue delivering the goods and services on which humanity ultimately depends may be undermined.
What are the basic necessities of life?
Ecosystems, whose functioning depends on biodiversity, provide the basic necessities of life (e.g., food, clean water and air), offer protection from natural disasters and disease (e.g., by regulating climate, floods and pests), and shape human cultures and spiritual beliefs.
Why is it important to maintain biodiversity?
One simple but profound answer is that all of us need to breathe, drink and eat. These are all benefits that are fundamentally provided by biodiversity. But the reasons to pause and consider the value of maintaining our country’s biodiversity are broader than this.

Research suggests that natural environments have direct and positive impacts on human well-being, despite the highly-urbanised modern lifestyles that most of us live. Mental-health benefits from exercising in natural environments have been are greater than those gained by exercising in the synthetic environment of the gym. Mood and self-esteem benefits are even greater if water is present.
What is the concept of diversity?
The concept includes every species of bacteria, virus, plant, fungi, and animal, as well as the diversity of genetic material within each species. It also encompasses the diverse ecosystems the species make up and the ongoing evolutionary processes that keep them functioning and adapting.
Why are ecosystem services important?
They enable plants to grow and therefore to feed us, keep pest species and diseases in check and help protect against flooding and regulate the climate. Loss of species could compromise the ecosystem services we rely on. CSIRO. These benefits are known as ecosystem services.
