IELTS Task 2 Sample on The Cost of Biodiversity Loss

You should spend about 40 minutes on this task. Write at least 250 words.
" The Cost of Biodiversity Loss" Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Biodiversity—the variety of life on Earth—underpins human wellbeing. The United Nations notes that more than half of global gross domestic product (GDP) depends on nature. Over 1 billion people rely on forests for their livelihoods and the land and oceans absorb more than half of all carbon emissions. Yet nature is in crisis: up to one million species are threatened with extinction within decades. Wetlands, which absorb significant carbon, have declined by 85 %. Destruction of ecosystems like parts of the Amazon rainforest has even turned some forests from carbon sinks into carbon sources. Humans have altered more than 70 % of ice‑free land primarily for food production. Climate change compounds these pressures, forcing animals and plants to move to higher elevations and latitudes, and increasing the risk of climate‑driven extinctions.

The economic consequences of nature loss are staggering. A 2025 SDG Action article estimates that unsustainable practices in food, land and ocean use cost about US$12 trillion per year, exceeding their contributions to global GDP. Harmful subsidies that degrade nature amount to US$4–6 trillion annually. The World Economic Forum’s Global Risks Report 2025 lists nature loss alongside climate change among the top four risks over the next decade. If unchecked, the destruction of ecosystems could destabilize financial markets; one analysis cited by the WEF suggests that US$58 trillion—55 % of global market capitalization—is highly or moderately dependent on nature. Ecosystem services worth US$10.6 trillion a year are lost to land degradation, and heat stress could cost the global economy up to US$25 trillion by 2060.

Halting biodiversity loss requires transforming how societies value and manage natural capital. Protecting and restoring forests, peatlands and mangroves offers two‑thirds of the mitigation potential of nature‑based solutions. The UN explains that peatlands, though covering only 3 % of land, store twice as much carbon as all forests, and mangroves can sequester CO₂ at rates up to four times higher than terrestrial forests. Integrating nature‑related risks into financial decision‑making, reforming harmful subsidies and investing in restoration could unlock US$10 trillion in annual business opportunities and create 395 million jobs by 2030. A nature‑positive economy—one that increases levels of nature over time—would not only stabilize the climate but also ensure long‑term economic and social resilience.

    While it is true that certain advancements- be it in technology, medicine, agriculture, transportation or any forms nation-building- don't free. Everyone has to sacrifice something in one form or another. This essay evaluates the Cost of Biodiversity Loss. Almost in every city of this world, people are expanding. What I mean is that, trees are being cut, rivers are block, and entire forests are being cleared to make room for condominiums, shopping centers, airports, and harbors. Something has to built, so something has to be removed. And what's even more sad is that mountains are being mined for minerals that are needed to make our smartphones. It's not just the mere fact of uprooting something that causes great damage to nature. It also disrupts habitats for animals indigenous to the area. Fishes and marine creatures suffer and die during oil excavations. Birds go extinct because of deforestation. And we have wiped out entire species all in the name going further. This is the sad reality of progress. On the other hand, we need to build data center, artificial intelligence headquarters, and clear areas to experiment on our newest inventions. The world is ever expanding. Humans are pushing the limits of science, technology, medicine every single day. We need these things to ensure the survival and adaptability of our species. Certain sacrifices have to be made. I feel like these points are the faces of the each side of a coin. One cannot deny that progress demands sacrifice but it shouldn't be at the expense of other living creatures or the destruction of our habitat. Maybe there is a way forward from this, a balance of well-meaning decisions that can guarantee our survival and progress and as well as maintaining the Earth- the only place we ever know.

    The loss of biodiversity has become a major concern because it can have serious economic, environmental, and social consequences. When plant and animal species disappear, ecosystems become less stable and less capable of providing essential services such as clean water, fertile soil, and pollination. As a result, agricultural productivity may decline, leading to food shortages and higher prices. In addition, many medicines are derived from natural resources, so the extinction of species could reduce opportunities for future medical discoveries. For example, the destruction of forests and wetlands has contributed to the decline of many species and increased the risk of natural disasters in some regions. From my own experience, I have noticed that fewer birds and insects can be seen in rural areas than in the past, which suggests that local ecosystems are gradually changing. Furthermore, biodiversity loss can negatively affect tourism, especially in countries that rely on their natural landscapes and wildlife attractions. Therefore, governments and individuals should take effective measures to protect endangered species and preserve natural habitats. By doing so, future generations will be able to enjoy a healthier and more sustainable environment.

    **The Cost of Biodiversity Loss** Biodiversity loss has become a serious problem in the modern world. It means the reduction of different types of plants, animals, and ecosystems. This loss brings many negative effects on nature and human life. One major cost is the imbalance of ecosystems. Every species has a role in nature. For example, bees help in pollination. If bees disappear, many crops will not grow properly. As a result, food production will decrease, and people may face food shortages. Another important issue is the impact on human health. Many medicines come from plants and animals. If these species become extinct, we may lose important medical resources. For instance, some cancer medicines are made from rare plants found in forests. Economic loss is also a big problem. Many people depend on forests, fisheries, and agriculture for their income. When biodiversity decreases, these sectors suffer. For example, overfishing reduces fish populations, which affects fishermen’s livelihoods. In my own experience, I have seen fewer birds and insects in my area compared to the past. This shows that biodiversity loss is real and visible. In conclusion, biodiversity loss has serious environmental, health, and economic costs. Therefore, we must protect nature to ensure a better future.
